pull ;excerpt ;neutralize ;tickle ;这英语用谐音怎么读?
普而;一可四儿普特;妞吹赖子;踢口儿2023-07-19 15:05:244
pull ;excerpt ;neutralize ;tickle ; 这英语用谐音怎么读?
1、pull 音标 [pu028al] ,谐音:扑o(扑噢)。这个单词和中文“扑”的读音比较接近,因为后面还有一个“l”的发言,接近拼音的o,所以我认为谐音“扑o”是相对接近的。2、excerpt音标 [u02c8eksu025cu02d0pt],谐音:艾克色扑特/艾克色pt。如果是谐音成中文,我觉得这几个是比较接近的,但是用中文谐音的话,有些该短的地方可能会有拖音。P、t后面没有元音,完全用“扑特”谐音过来,读的时候可能会长一点,如果要更加接近原来的英文读音,这种没有元音的,完全可以用原字母,我认为比较接近的谐音是“艾克色pt”3、neutralize 音标 [u02c8njuu02d0tru0259lau026az] :谐音“纽彻莱斯”,英文和中文有些音比较接近,可能因为国内外语言习惯不同,在一些辅音上面还是有些出入的,这个谐音不算很接近,但是是我能想到最接近的谐音。在读“彻”和“斯”时,舌尖在上颚位置就可以,太往后过于清澈,接近中文而偏离英文读音 了。4、tickle 音标[u02c8tu026akl] ,谐音:“梯口”,读中文的时候我们会把“梯”的音读的长一点,要想接近这个单词的英文音,在念谐音时,念得短一点。2023-07-19 15:05:393

有关胃药active ingredient
更新1: 咁即系 Citric acid只系for俾返个胃少少acidic?? 但点解可以刚刚会的分量neutralize stomach acidic while 又唔会neutralize到citric acid的acidic? 系咪现多选用carbonate的胃药 虽然胃气涨? 但因为冇其他如肚泻的副产品?? thanks 胃药个active ingredient其实应该系magnseium hydroxide又或者aluminium hydroxide... 大多数胃药都离唔开呢两种 因为胃药系要中和胃部既酸性...所以个active ingredient一定系alkaline既野...但有d胃药会加solid acid 咁系唔好俾d alkaline中和晒所有acid d solid acid可以补充番失去左既acid 令个胃舒服d咁姐.......随左citric acid 仲会加左starch 不过呢d唔系active ingredient..... 有d胃药既ingredient系 magnesium carbonate会出好多gas 如果胃药既ingredient系carbonate 食左之后会有胃气 令胃部唔舒服 co2系by-product黎既 MgCO3 + 2HCl出MgCl2 CO2 同H2O NaHCO3 + HCl出NaCl CO2 同H2O 含有hydroxide e.g magnesium hydroxide会有轻泻作用 但aluminium hydroxide就会令人便秘..... 要搞清楚一点就系active ingredient意思系指"有效成分" 通常用化学物质占一粒药丸几多个percentage黎定 所以胃药既active ingredient只系指carbonate/hydroxide 唔系一d中和唔到胃酸既chemical e.g citric acid/starch 2006-11-21 16:39:01 补充: citric acid虽然系weak acid 但你够唔够胆话citric acid 个pH值唔低????无错citric acid系weak acid 咁只系代表佢杀唔到菌 唔代表佢唔系acidic woo 2006-11-21 16:41:44 补充: Na2CO3系碱性Na2CO3 HCl出NaHCO3NaHCO3再同HClreact出NaCl CO2 同H2O 2006-11-24 11:35:59 补充: 1. 又或者我咁讲 d alkaline溶左落水之后有d会同ca react左先 咁会冇咁多alkaline同胃酸react 你又可能会问: 咁alkaline个份量唔好俾咁多 咁咪唔使用到ca law.其实系唔同人有唔同既胃酸concentration 我地要照顾一d胃酸分泌冇咁多人ga ma 有d人一粒pill都多得济 咁ca都会帮到手.如果胃酸太多 中和之后都应该回复到正常水平 如果有ca仲未react晒 咁咪当vitamin c 咁黎吸收law ca对人体无害 唔须要border个ca有咩用 2006-11-24 11:36:12 补充: 2. 我谂上面答左你.但其实药厂系唔会将alkaline个concentration较到刚好react晒所有acid ga3. yes..你想胃气涨抑或便秘??答案好明显但因为冇其他如肚泻的副产品??carbonate唔会引起便秘或肚泻 NaCl同MgCl都系salt 会被吸收 你睇番条equation 但放出CO2系副产品定系特登? 放出CO2系副产品 因为胃药 要有alkaline for neutralize 胃酸 but as you know the tablet of the 胃药 is a hard solid and the total surface area is paratively *** all if the tablet can be broken into very tiny pieces the total surface area is very large and this can make the reaction of nuetralization much faster........ and if the tablet contact water the gasing effect of citric acid and sodium hydrogen carbonate can make this happen....... By the way citric acid is a weak acid(pare with your stomach fluid) it cannot enhanced the acidity in this case.......2023-07-19 15:08:421

为何有酸雨没有碱雨?
碱系唔会有气体 所以唔会系空气中停留而造成碱雨. 碱基系一些金属离子 如NaOH 一定是ionic bond 吸力好强 所以排成一个正 负离子既大阵 即系成千上万既离子排成一个立方体 而唔只一正一负两个离子咁存在. 咁大个阵一定唔会系气体 而系固体. 而你列举既CO2 CO NO2等系covalent bond CO2 就只系一个C同两个O 系唔会黏到其他既CO2 3只野[而唔系成千上万]拖住仲可以自由系空中飞来飞去:系气体. 不过记住 形成酸雨的气体本身系covalent 即系唔系酸性既 只系溶解系水度 产生左H+离子 至有一滴滴酸性的水. 相反 碱基本身已有OH- 已算得是碱性了. 参考: F.5 CHEMISTRY 酸雨正式的名称应为酸性沈降,是人为污染,NO3-及 SO2-4 为主要的致酸物质,其硫氧化物与氮氧化物转化而来。 其他致酸物质:Na+、Cl-、Mg2+、NO3、Ca2+、K+、NH4+。 但人类不会排放致碱物质,所以没有碱雨。 参考: *** 因为天空中没有碱性的气体,所以碱唔可以dissolve in the rain,如果有嘅话应该有碱雨=.= 因为空气中冇碱 就算有 都会比carbon dioxide neutralize 左 变做普通的雨2023-07-19 15:10:051

materialstudio算离子怎么设置
1、首先用MS的话,先画一个NA原子,然后设置一个正电荷就成了,再然后在Modules—AmorphousCell—Calculation中选中画好的NA,设置个数就行了。2、其次用VMD的话,可以把水盒子载入VMD,然后EXtensions—modeling—AddIons,在对话框里点中OnlyneutralizesystemwihNaCL,自动就能添加足够个数的钠离子,使体系中和。3、最后使用packmol的话,直接在输入文件中写NA的个数即可。2023-07-19 15:10:551
哪位大仙可以告诉我等当量点(equivalence point)到底是什么!!!急!!!
滴定反应需要灵敏的指示剂来指示反应的完成。指示剂在反应完成时,会迅速变成另一种颜色,这样实验者就可以根据指示剂的变色来确定反应的终止。这两个变化通常不是同时完成的,反应定量完成时的状态叫计量点(stoichiometric point)或当量点(equivalence point),指示剂变色时的状态叫滴定终点(end point)。然而通过选用恰当的指示剂可以将指示剂带来的误差(称作终点误差,end point error)降到允许范围之内。2023-07-19 15:11:162

1.If you want to spark a heated debate at a dinner party, bringup the topic of geneticallyModifiedfoods. For many people, the concept of genetically altered, high-tech cropproduction raises all kinds of environmental, health, safety and ethicalquestions. Particularly in countries with long agrarian traditions -- and vocalgreen lobbies -- the idea seems against nature. 如果你想在某次晚宴上挑起一场激烈的争论,那就提出转基因食品的话题吧。对许多人来说,高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。特别是在有悠久的农业生产传统和主张环保的游说集团的国家里,转基因食品的主意似乎有悖自然。2. Infact, genetically modified foods are already very much a part of our lives. Athird of the corn and more than half the soybeans and cotton grown in the USlast year were the product of biotechnology, according to the Department ofAgriculture. More than 65 million acres of genetically modified crops will beplanted in the US this year. The genetic is out of the bottle. 事实上,转基因食品已经成为我们生活重要的一部分。根据农业部的统计,美国去年所种植玉米的1/3,大豆和棉花的一半以上都是生物技术的产物。今年,美国将种植6500多万英亩的转基因作物。基因妖怪已经从瓶子里跑出来了。3.Yet there are clearly some very real issues that need to beresolved. Like any new product entering the food chain, genetically modifiedfoods must be subjected to rigorous testing. In wealthy countries, the debateabout biotech is tempered by the fact that we have a rich array of foods tochoose from -- and a supply that far exceeds our needs. In developing countriesdesperate to feed fast-growing and underfed populations; the issue is simplerand much more urgent: Do the benefits of biotech outweigh the risks?但是,显然还有一些非常现实的问题需要解决。就像任何一种要进入食物链的新食品一样,转基因食品必须经过严格的检验。在富裕的国家里,由于有大量丰富的食品可供选择,而且供应远远超过需求,所以关于生物技术的争论相对缓和一些。在迫切想要养活其迅速增长而又吃不饱的人口的发展中国家,问题比较简单,也更加紧迫:生物技术的好处是否大于风险呢?4.The statistics on population growth and hunger are disturbing.Last year the world"s population reached 6 billion. And by 2050, the UNestimates, it will probably near 9 billion. Almost all that growth will occurin developing countries. At the same time, the world"s available cultivableland per person is declining. Arable land has declined steadily since 1960 andwill decease byhalf over the next 50 years, according to the InternationalService for the Acquisition of Agri-Biotech Applications (ISAAA).关于人口增长和饥饿的统计数字读来令人感到不安。去年,世界人口达到了60亿。联合国预测,到2D0年,这个数字很可能将接近90亿,而增加的人口几乎都来自发展中国家。与此同时,世界人均耕地正在减少。国际农业生物工程应用技术采购管理局(ISAAA)称,自1960年以来,耕地面积一直持续下降,并将在今后50年减少一半。5The UN estimates that nearly 800 million people around theworld are undernourished. The effects are devastating. About 400 million womenof childbearing age are iron deficient, which means their babies are exposed tovarious birth defects. As many as 100 million childrensuffer from vitamin A deficiency, a leading cause of blindness.Tens of millions of people suffer from other major ailments and nutritionaldeficiencies caused by lack of food.联合国估计,世界上有近8亿人口营养不良。它产生的效应是破坏性的。大约有4亿的育龄妇女体内缺铁,也就是说,她们的婴儿将可能有各种天生的缺陷。数量多达1亿的儿童缺乏维生素A,这是导致失明的主要原因。还有数千万的人患有因食物匮乏而导致的其他严重疾病和营养不良症。6How can biotech help? Biotechnologists have developedgenetically modified rice that isfortified with beta-carotene -- which the body converts intovitamin A -- and additional iron, and they are working on other kinds ofnutritionally improved crops. Biotech can also improvefarming productivity in places where food shortages are causedby crop damage attribution to pests, drought, poor soil and crop viruses,bacteria or fungi.生物技术对此能做些什么呢?生物技术专家已经培育出了含有β—胡萝卜素(身体可将之转化为维生素A)和更多铁元素的转基因水稻,目前正在研究培育其他一些增进营养成分的农作物。生物技术还可以帮助提高因虫害、干旱、土壤贫瘠和作物病毒、细菌或真菌导致作物减产而出现食物匮乏的地区的农业生产率。7Damage caused by pests is incredible. The European corn borer,for example, destroys 40 million tons of the world"s corn crop annually, about7% of the total. Incorporatingpest-resistant genes into seeds can help restore the balance. Intrials of pest-resistant cotton in Africa, yields have increased significantly.So far, fears that genetically modified,pest-resistant crops might kill good insects as well as badappear unfounded.虫害带来的损失令人难以置信。例如,欧洲玉米螟每年毁掉4000万吨玉米,占世界玉米总产量的7%。把抗虫害的基因植入种子可以帮助避免这一损失。在非洲进行的抗虫害棉花试验中,棉花的产量已大幅度提高。有人担心,抗虫害的转基因作物不仅将害虫杀死,而且有可能连益虫也一起杀死,但到目前为止,这种担心似乎没有根据。8Viruses often cause massive failure in staple crops indeveloping countries. Two years age, Africa lost more than half its cassavacrop -- a key source of calories -- to the mosaic virus. Genetically modified,virus-resistant crops can reduce that damage, as can drought-tolerant seeds inregions where water shortages limit the amount of land under cultivation.Biotech can also help solve the problem of soil that contains excess aluminum,which can damage roots and cause many staple-crop failures. A gene that helpsneutralize aluminum toxicity in rice has been identified.病毒常常在发展中国家造成主要粮食作物的大面积歉收。两年前,花叶病毒使非洲损失了超过一半的木薯,而这种作物是当地人的主要食物。转基因的抗病毒作物可以减少这种损失,就像抗干旱种子在可耕地面积因缺水而受到限制的地区起到的作用一样。含铝过高的土壤会损伤作物的根系并使许多主要作物歉收,对于这种问题生物技术也能帮助解决。目前,研究人员已经识别出一种有助于中和水稻里铝的毒性的基因。9Many scientists believe biotech could raise overall cropproductivity in developing countries as much as 25% and help prevent the lossof those crops after they are harvested.许多科学家认为,生物技术能够把发展中国家的农业总产量提高25%,并且帮助防止作物收割后遭受损失。10Yet for all that promise, biotech is far from being the wholeanswer. In developing countries, lost crops are only one cause of hunger.Poverty plays the largest role. Today more than 1 billion people around theglobe live on less than " 1 aday. Making genetically modified crops available will not reduce hunger iffarmers cannot afford to grow them or if the local population cannot afford tobuy the food those farmers produce.尽管具有这么多潜力,生物技术还远远不能解决全部问题。在发展中国家,作物歉收只是造成饥饿的一个原因。贫穷才是罪魁祸首。今天,全世界有超过10亿人口每天靠不到1美元维持生计。如果农民没钱种植转基因作物或当地人买不起农民种出的粮食,培育转基因作物就无法减少饥饿。11Nor can biotech overcome the challenge of distributing food indeveloping countries. Taken as a whole, the world produces enough food to feedeveryone -- but much of it is simply in the wrong place. Especially incountries with undeveloped transport infrastructures, geographyrestricts foodavailability as dramatically as genetics promises to improve it.此外,生物技术也无法克服在发展中国家分配粮食的难题。从整体上看,世界生产的粮食足够养活所有人,但大部分粮食却不是在需要的地方。尤其在运输基础设施落后的国家,地理条件对食物供给的限制正如遗传学为食物供给带来的希望一样大。12Biotech has its own "distribution" problems.Private-sector biotech companies in the rich countries carry out much of theleading-edge research on genetically modified crops. Their products are oftentoo costly for poor farmers in the developing world, and many of those productswon"t even reach the regions where they are most needed. Biotech firms have astrong financial incentive to target rich markets first in order to help themrapidly recoup the high costs of product development. But some of thesecompanies are responding to needs of poor countries. A London-based company,for example, has announced that it will share with developing countriestechnology needed to produce vitamin-enriched "golden rice".生物技术也面临自身的“分配”问题。许多转基因作物方面的尖端研究都是富国的私营生物技术公司进行的。对发展中国家的穷苦农民来说,这些公司的产品通常显得过于昂贵,而且这些产品中的大部分甚至无法到达最需要的地区。强大的经济刺激促使生物技术公司把富裕国家的市场作为第一目标,以便能够尽快回收产品开发的高额成本。不过,有些公司已开始对贫穷国家的需要做出反应。例如,一家总部在伦敦的公司已经宣布,它愿意和发展中国家一起分享生产维生素增强型的“金水稻”所需的技术。13More and more biotech research is being carried out indeveloping countries. But to increase the impact of genetic research on thefood production of those countries, there is a need for better collaborationbetween government agencies -- both local and in developed countries -- andprivate biotech firms. The ISAAA, for example, is successfully partnering withthe USAgency for International Development, local researches andprivate biotech companies to find and deliver biotech solutions for farmers indeveloping countries.发展中国家正在进行越来越多的生物技术研究。但是,为扩大遗传学研究对这些国家的粮食生产的影响,政府各部门(包括当地政府部门和发达国家的政府部门)与私营生物技术公司之间需要更好的合作。例如,国际农业生物工程应用技术采购管理局目前正与美国国际发展署、当地的研究人员以及私营的生物技术公司进行成功的合作,以帮助发展中国家的农民寻求生物技术方面的解决办法。14Will "Frankenfoods" feed the world? Biotech is not apanacea, but it does promise to transformagriculture in many developingcountries. If that promise is not fulfilled, the real losers will be theirpeople, who could suffer for years to come.“弗兰肯食品”能养活世界吗?生物技术虽不是万灵药,但它确实有希望改造许多发展中国家的农业。如果这种希望不能实现,真正的受害者将是这些国家的人民,他们可能会在未来的岁月里遭受苦难。~快采纳我~2023-07-19 15:11:501

找一篇有关阿司匹林的英语短文
Aspirin"s history is a lengthy one, from its discovery in the fifth century BC, to its use as a bartering tool in World War I, to its newly discovered benefits and uses.A person could get a headache thinking about all of the detours aspirin has taken on the road to becoming today"s common, inexpensive, cure-all medication. Aspirin"s roots are deep, and reach back to Hippocrates himself, the Greek father of modern medicine, who held the recipe for a pain reliever and fever reducer made from the bark and leaves of the willow tree. The key the Greek father of modern medicine held from sometime between 460 and 377 BC, was buried with him, and was not rediscovered until 1758 by an English clergyman.Scientists, now aware of the pain relieving properties of willow bark, struggled to strip it down to the exact ingredient responsible for its powers, and finally did so in the 1820s. They narrowed their search to salicin, an early form of the family of drugs named salicylates, of which aspirin is a member.Severe stomach upset from the salicylic acid extracted willow bark posed a problem for scientists. They attempted to remedy this side effect by combining the acid with sodium to neutralize the acid, but it failed to reduce the belly aching. A French chemist, Charles Frederic Gerhardt put an end to the dilemma in 1853, by adding acetyl chloride to the sodium salicylate mixture. He published the results of his findings, but did not pursue his creation past this point, even though it upset the stomach less than the currently available compound. Mr. Gerhardt saw no future in the time-consuming preparation of his recipe, which he felt did not improve much upon the original medicine. His decision left people grabbing their guts, and stomaching the old standby, sodium salicylate.Salvation came in 1897, in the person of an eager, young Felix Hoffman, who sought, and found, a drug to help relieve the painful symptoms of his father"s arthritis. This driven chemist, an employee of the Bayer Company, found and dusted off Gerhardt"s old publication, mixed a batch of the recipe, and discovered that it actually worked.Hoffman used his connection with his employer to pitch his idea, and Bayer reluctantly agreed to produce the medicine they named Aspirin. They invented the name Aspirin by combining the initials A from acetyl chloride, the SPIR from the plant they extracted the salicylic acid from, Spirae ulmaria, and the IN, because it was the common ending for medications at that time. Bayer launched Aspirin in powder form and as a tablet in 1915. Aspirin was an instant success.Aspirin"s success ended up costing the Bayer Company a great deal of money, when the U.S., England, France, and Russia forced it to surrender the trademark to them, as part of Germany"s war reparations at the close of World War I. Bayer gave up the trademark in 1919, as part of the Treaty of Versailles, which explains why the aspirin, stripped of its trademark, is now written in the lower case.Today, aspirin holds the title of being the most widely used drug, one that is no longer solely used as a pain reliever and as a fever reducer. Physicians have shown aspirin to be effective in combating arthritis pain, in reducing the risk of heart disease, of death following a heart attack, of cancer. It is doubtful that aspirin will ever again be lost to the annals of history.2023-07-19 15:13:421
关于an apple a day keeps the doctor away的作文
It"s one of the most recognizable expressions around: "An apple a day keeps the doctor away." But besides the fact that it rhymes, which makes it fun to say and easy to recall, does it really have any value? Could the common apple honestly help a person to maintain perfect health?The first printed mention of this saying can be found in the February 1866 issue of the publication "Notes and Queries." The publication printed the proverb like this: "Eat an apple on going to bed, and you"ll keep the doctor from earning his bread." Nearly 150 years later, variations of this adage are still quoted. It"s unlikely that the saying would have maintained such popularity if there wasn"t some truth to it, right? With that in mind, let"s consider some of the apple"s components and their effect on our health:*Pectin -- Pectin is a form of soluble fiber than lowers both blood pressure and glucose levels. It can also lower the levels of LDL, or "bad" cholesterol in the body. Pectin, like other forms of fiber, helps maintain the health of the digestive system. Apples are an excellent source of pectin.*Boron -- A nutrient found in abundance in apples, boron supports strong bones and a healthy brain.*Quercetin -- A flavonoid, this nutrient shows promise for reducing the risk of various cancers, including cancers in the lungs and breast. It may also reduce free radical damage. Free radicals develop when atoms in the body"s cells have unpaired electrons, which can lead to damage to different parts of the cell, including DNA. Quercetin may neutralize free radical damage, which has been implicated in a variety of age-related health problems, including Alzheimer"s disease.*Vitamin C -- Vitamin C boosts immunity, which helps maintain overall health.*Phytonutrients -- Apples are rich in a variety of phytonutrients, including vitamins A and E and beta carotene. These compounds fight damage from free radicals and can have a profound affect on health, including reducing the risk of heart disease, diabetes and asthma.Apples also act as a toothbrush, cleaning teeth and killing bacteria in the mouth, which may reduce the risk of tooth decay. They"re also low in calorie density, one of the trademarks of a healthy food. When a food is low in calorie density you can eat good size portions of the food for relatively few calories. In addition, apples are affordable and readily available.With all of this information, it"s easy to see that, yes, an apple has its health benefits. But does eating an apple every day mean you"ll never get sick? And is an apple really healthier than other fruits?2023-07-19 15:13:521

写作思路:要直接简化任务语言。在叙述中,我们要把直接叙述变成间接叙述,尽可能简化人物语言。这样,即使情节连贯,又使语句“简练”。In the winter holiday.I read a book.It is very wonderful.Its name is "The monkeys paw".The book tells about the Whites and a paws story.Mr.Whites friend gave him a small and dirty paw.He said "It can makes your dreams come true.But youll feel unhappy."Mr.White wanted ?3000.And after some days,he got ?3000,but his son deid.The end is Mr.White and his wife were very sad.I think“The monkeys paw”is very useful.Because it tells us some important things.Such as "get something for nothing." is impossible.We must do every things by ourselves.And we must know learn by doing.When I was 10 years old.I was not good at math.And I had tried to find many escape solutions.But no one is good for me.My mother tolds me,"learn by doing",and I did some test questions.Now,my math is ok.I think my story likes "The monkeys paw".And in the new future,I will do every things by my self and do not rely on my father and mother.I know I am the best.What a nice story!“The monkeys paw”is perfect,and I will learn more and more in it.译文:在寒假里。我读了一本书。它非常棒。它的名字是“猴子的爪子”。这本书讲述了白人和爪子的故事。怀特先生的朋友给了他一只又小又脏的爪子。他说:“它能让你的梦想成真。但你会感到不快乐。”怀特先生想要3000英镑。几天后,他得到了3000英镑,但他的儿子戴德。结局是怀特先生和他的妻子非常伤心。我认为“猴爪”是非常有用的。因为它告诉我们一些重要的事情。比如“免费得到一些东西”。这是不可能的。我们必须自己做每件事。我们必须知道在实践中学习。当我10岁的时候,我不擅长数学。我试图找到很多逃避的方法。但是没有人对我有好处。我妈妈告诉我“边做边学”,我做了一些测试题。现在,我的数学还不错。我想我的故事就像“猴子爪”。在新的未来,我会自己做每件事,不依赖父母。我知道我是最好的。多好的故事啊!”“猴爪”很完美,我会在里面学到更多。2023-07-19 15:15:172

历史是个ydvj艺术绘画吗56?
我们对史前绘画的了解是从出土的彩陶及遍布全国的岩画遗存中得来的,而今天的我们有理由相信,这些作品的创作大多出于宗教和巫术的目的,并不是出于审美和欣赏的需要。绘画的萌芽石器时代是中国绘画的萌芽时期,伴随着石器制作方法的改进,原始的工艺美术有了发展。但在若干年以前,我们所掌握的中国绘画的实例还只是那些描画在陶瓷器皿上的新石器时代的纹饰。但,在中国的许多省份发现了岩画,使得史学家们将中国绘画艺术的起源推前至旧石器时代。在这些众多的发现中,也包括了许多描绘人的图像,有些堪称宏幅巨制。内蒙古阴山岩画就是最早的岩画之一。在那里,我们的先人们在长达一万年左右的时间内创作了许多这类图像,这些互相连接的图像把整个山体连变成了一条东西长达300公里的画廊。据推测,是宗教或巫术的感召促使先人们不辞辛劳地创作了这些图像。类似的图像还可以在苏北的连云港孔望山将军崖岩画遗址中见到。新石器时代的绘画艺术探讨新石器时代的绘画,我们仍然要把目光投向那些地处边远地区的神秘岩画。在云南沧源发现的岩画反映了人类的活动,包括狩猎、舞蹈、祭祀和战争。岩画的构图更趋于复杂,所表现的内容也由单个的物体发展为互相关联的具有动感的人。它们的存在使我们看到了中国绘画发展的一个重要时期。当然,这个时期的“艺术家”们在绘制岩画的时候并没有任何的边界的限制,岩面也并没有作任何的处理,它们的创作是无拘无束的。这一切的改变源自于陶器和木结构建筑的出现,具有创造力和想象力的艺术家们马上就发现这些材料是绝好的作画之处,于是,缤纷的色彩和丰富的纹样出现在这些器物上。以质朴明快、绚丽多彩为特色的仰韶文化与马家窑文化的彩陶图案,是我国先民的杰出创造。此外,大汶口文化、红山文化、河姆渡文化等,也有一定数量的彩陶。仰韶类型的彩陶以在西安出土的半坡陶盆《人面鱼纹盆》最具特色,也最耐人寻味,关于这种图案具体的含意一直在猜测之中。庙底沟类型的彩陶的图像中最引人注目的是绘制于陶缸上的《鹳鸟石斧图》,出土于河南临汝闫村。该图以写实手法所描绘的鸟、鱼及斧据说代表了鹳氏族兼并鱼氏族的历史事件。先秦绘画在整个“先秦”时代中,春秋以前属于奴隶制社会,战国以后则进入了封建社会。伴随着社会分工的扩大,各种手工业得到了极大的发展,出现了所谓的“青铜文明”。统治阶级的需要带动了美术各门类的发展,绘画当然也不例外,有了长足的发展。但是,我们今天能够见到的先秦绘画遗迹少之又少,造成这种现象的原因被推测为大部分的绘画都绘制在了易于腐烂的木质或者布帛上面。在商代的多处墓葬中发现了残存的彩绘布帛,在商代王室的墓葬中更是发现了很多的木质品上的漆画残留。可见,用漆作为颜料绘制器物在当时已很广泛了,常用的黑、红两种基本色的并置形成了强烈的对比。据说,那时的漆绘制品经常是与铮亮的青铜器以及白色的陶器摆在一起的,极富观赏性。在殷墟也曾发现过建筑壁画的残块,以红、黑两色在白灰墙皮上绘出的卷曲对称的图案,颇有装饰趣味。西周、春秋、战国时期都有庙堂壁画创作的情况被记载下来,楚国屈原著名作品的《天问》就是在观看了楚先王庙堂的壁画后有感而作的。 幸运的是,在长沙的楚墓中先后出土了两幅战国时期的带有旌幡性质的帛画,它们都属于公元前3世纪的作品。两画描绘的都是墓主的肖像,一幅为妇人,其上方绘有飞腾的龙凤;另一幅则是一位有身份的男子,驾驭着一条巨龙或龙舟。墨线勾勒的侧面肖像及伴有象征意义的动物是两画的相同之处,所不同的是《人物御龙图》所表现出来的画家技巧要熟练了许多。秦汉绘画秦汉时期是中国民族艺术风格确立与发展的极为重要的时期。公元前221年,秦始皇统一中国后在政治、文化、经济领域的一系列改革使得社会产生了巨大的变化。为了宣扬功业,显示王权而进行的艺术活动,在事实上促进了绘画的发展。西汉统治者也同样重视可以为其政治宣传和道德说教服务的绘画,在西汉的武帝、昭帝、宣帝时期,绘画变成了褒奖功臣的有效方式,宫殿壁画建树非凡。东汉的皇帝们同样为了巩固天下,宣扬“天人感应”论及“符瑞”说,祥瑞图像及标榜忠、孝、节、义的历史故事成为画家的普遍创作题材。汉代厚葬习俗,使得我们今天可以从陆续发现的壁画墓、画像石及画像砖墓中见到当时绘画的遗迹。秦汉时代艺术以其深沉雄大的气魄,在中国美术史上放射着夺目的光彩。绘画艺术秦汉时代的绘画艺术,大致包括宫殿寺观壁画、墓室壁画、帛画等门类。2023-07-19 15:09:171
请问IC和IT的区别是什么拜托各位大神
IC就是半导体元件产品的统称。包括:1.集成电路板(integrated circuit,缩写:IC); 2.二、三极管;3.特殊电子元件。 再广义些讲还涉及所有的电子元件,象电阻,电容,电路版/PCB版,等许多相关产品。 IT的英文是Information Technology,即信息产业的意思,较为广泛:目前IT业的划分方法有各式各样,其中以美国商业部的定义较为清楚和合理,它将国民经济的所有行业分成IT业和非IT生产业。其中IT业又进一步划分为IT生产业和IT使用业。IT生产业包括计算机硬件业、通信设备业、软件、计算机及通信服务业。至于IT使用业几乎涉及所有的行业,其中服务业使用IT的比例更大。由此可见,IT行业不仅仅指通信业,还包括硬件和软件业,不仅仅包括制造业,还包括相关的服务业,因此通信制造业只是IT业的组成部分,而不是IT业的全部。2023-07-19 15:09:211
ISA网卡跟PCI网卡有什么区别?
ISA接口的网卡有两种:8位ISA网卡和16位ISA网卡。8位ISA网卡目前已被淘汰,市场上常见的是16位ISA接口的10M网卡,它的惟一好处就是价格低廉,如比较有名的NE2000等,适合于一些如网吧等要求不高的场合使用。而VESA、EISA网卡速度虽然快,但价格较贵,市场很少见。目前市场上的主流网卡是PCI总线的网卡。PCI网卡的理论带宽为133M。PCI网卡又可分为10M PCI网卡和10/100M PCI自适应网卡两种类型。10M PCI网卡价格较便宜,被低端用户广泛采用;而10/100MPCI自适应网卡作为当今的主流产品,可根据需要自动识别连接网络设备的工作频率,自动工作于10M或100M的网络带宽下。PCI总线网卡的另一好处是比ISA网卡的系统资源占用率要低得多。USB接口网卡,主要是为了满足没有内置网卡的笔记本用户。它通过主板上的USB接口引出来的。http://act.it.sohu.com/book/chapter.php?id=368&volume=3&chapter=12023-07-19 15:09:041

黑客(hacker)是一个喜欢用智力通过创造性方法来挑战脑力极限的人,特别是他们所感兴趣的领域,例如电脑编程或电器工程。 黑客最早源自英文hacker,早期在美国的电脑界是带有褒义的。但在媒体报导中,黑客一词往往指那些“软件骇客”(softwarecracker)。 黑客一词,原指热心于计算机技术,水平高超的电脑专家,尤其是程序设计人员。 但到了今天,黑客一词已被用于泛指那些专门利用电脑网络搞破坏或恶作剧的家伙。对这些人的正确英文叫法是Cracker,有人翻译成“骇客”。 黑客和骇客根本的区别是:黑客们修补漏洞,而骇客们利用漏洞进行破坏。 也有人叫黑客做Hacker。 黑客一词一般有以下四种意义: 一个对(某领域内的)编程语言有足够了解,可以不经长时间思考就能创造出有用的软件的人。 一个恶意(一般是非法地)试图破解或破坏某个程序、系统及网络安全的人。这个意义常常对那些符合条件(1)的黑客造成严重困扰,他们建议媒体将这群人称为“骇客”(cracker)。有时这群人也被叫做“黑帽黑客”。 一个试图破解某系统或网络以提醒该系统所有者的系统安全漏洞。这群人往往被称做“白帽黑客”或“匿名客”(sneaker)或红客。许多这样的人是电脑安全公司的雇员,并在完全合法的情况下攻击某系统。2023-07-19 15:09:021

关于集成电路设计的流程详解
集成电路设计(英语:Integratedcircuitdesign),根据当前集成电路的集成规模,亦可称之为超大规模集成电路设计(VLSIdesign),是指以集成电路、超大规模集成电路为目标的设计流程。集成电路设计通常是以“模块”作为设计的单位的。例如,对于多位全加器来说,其次级模块是一位的加法器,而加法器又是由下一级的与门、非门模块构成,与、非门最终可以分解为更低抽象级的CMOS器件。下面就让我们进一步的了解集成电路设计的相关知识。集成电路设计介绍集成电路设计的流程一般先要进行软硬件划分,将设计基本分为两部分:芯片硬件设计和软件协同设计。芯片硬件设计包括:1.功能设计阶段。设计人员产品的应用场合,设定一些诸如功能、操作速度、接口规格、环境温度及消耗功率等规格,以做为将来电路设计时的依据。更可进一步规划软件模块及硬件模块该如何划分,哪些功能该整合于SOC内,哪些功能可以设计在电路板上。2.设计描述和行为级验证功能设计完成后,可以依据功能将SOC划分为若干功能模块,并决定实现这些功能将要使用的IP核。此阶段间接影响了SOC内部的架构及各模块间互动的讯号,及未来产品的可靠性。决定模块之后,可以用VHDL或Verilog等硬件描述语言实现各模块的设计。接着,利用VHDL或Verilog的电路仿真器,对设计进行功能验证(functionsimulation,或行为验证behavioralsimulation)。注意,这种功能仿真没有考虑电路实际的延迟,也无法获得精确的结果。3.逻辑综合确定设计描述正确后,可以使用逻辑综合工具(synthesizer)进行综合。综合过程中,需要选择适当的逻辑器件库(logiccelllibrary),作为合成逻辑电路时的参考依据。硬件语言设计描述文件的编写风格是决定综合工具执行效率的一个重要因素。事实上,综合工具支持的HDL语法均是有限的,一些过于抽象的语法只适于作为系统评估时的仿真模型,而不能被综合工具接受。逻辑综合得到门级网表。4.门级验证(Gate-LevelNetlistVerification)门级功能验证是寄存器传输级验证。主要的工作是要确认经综合后的电路是否符合功能需求,该工作一般利用门电路级验证工具完成。注意,此阶段仿真需要考虑门电路的延迟。5.布局和布线布局指将设计好的功能模块合理地安排在芯片上,规划好它们的位置。布线则指完成各模块之间互连的连线。注意,各模块之间的连线通常比较长,因此,产生的延迟会严重影响SOC的性能,尤其在0.25微米制程集成电路设计过程1.电路设计依据电路功能完成电路的设计。2.前仿真电路功能的仿真,包括功耗,电流,电压,温度,压摆幅,输入输出特性等参数的仿真。3.版图设计(Layout)依据所设计的电路画版图。一般使用Cadence软件。4.后仿真对所画的版图进行仿真,并与前仿真比较,若达不到要求需修改或重新设计版图。5.后续处理将版图文件生成GDSII文件交予Foundry流片。集成电路设计的辅助和自动化主条目:计算机辅助设计和电子设计自动化由于集成电路系统的复杂性,工程师往往需要借助电子设计自动化工具来进行计算机辅助设计。逻辑综合就是电子设计自动化在数字集成电路设计中最显著的体现。以往在设计小规模、中规模集成电路时,工程师设计数字集成电路需要根据逻辑功能,通过类似卡诺图这样的手工途径来优化逻辑函数,然后确定使用何种逻辑门来实现电路。而在当前超大规模集成电路,乃至更大的甚大规模集成电路的设计中,这样的工作方式不太现实。电子设计自动化工具使得工程师能够从复杂的门级设计转到功能设计,而底层的转换由自动工具完成,工程师只需要掌握如何设置这些工具工作策略的知识。硬件描述语言是集成电路设计自动化的重要基础。电子设计自动化发展十分迅速,现在已经成立了诸如设计自动化会议的一些学术论坛,定期讨论业界的发展。完成整个集成电路设计常常涉及多个电子设计自动化工具的运用。有些公司专门从事集成电路计算机辅助设计工具套件的开发和销售,例如Synopsys、Cadence、MentorGraphics、Agilent、Altium、Xilinx等。电子设计自动化工具的本身作为一种软件,背后依靠的是各种计算机算法。因此电子设计自动化工具的开发更加接近软件设计的范畴,其开发人员需要重点关注逻辑简化、布局布线等方面的算法实现,但是他们同样需要了解集成电路的硬件知识。编辑总结:2023-07-19 15:09:001
