到网上查啊~这是wikipedia的解释:
The equivalence point, or stoichiometric point, of a chemical reaction is when a titrant is added and is stoichiometrically equal to the number of moles of substance (known as analyte) present in the sample: the smallest amount of titrant that is sufficient to fully neutralize or react with the analyte.
酸碱中和时(尤其是滴定实验时),酸的氢离子摩尔数等于碱的氢氧离子摩尔数,正好中和形成盐和水的溶液,此时称为当量点。
酸碱滴定中三个重要的点:
当量点:酸的当量数=碱的当量数(二者正好完全反应)
终点:指示剂变色的点.
中和点:酸碱滴定过程中,容易恰成中性的点. 即pH=7
注意:(当量点才是恰好完全反应的点)
当量点不一定等于终点.
当量点不一定等于中性.

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。

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

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

10篇书虫读后感要初中水平英文的
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

AGP,PCI,ISA是什么意思?它们的完整英文是什么?
其工作频率为8MHz左右,为16位插槽,最大传输率16MB/sec,可插接显卡,声卡,网卡已及所谓的多功能接口卡等扩展插卡。其缺点是CPU资源占用太高,数据传输带宽太小,是已经被淘汰的插槽接口。目前还能在许多老主板上看到ISA插槽,现在新出品的主板上已经几乎看不到ISA插槽的身影了,但也有例外,某些品牌的845E主板甚至875P主板上都还带有ISA插槽,估计是为了满足某些特殊用户的需求。 PCI插槽是基于PCI局部总线(Pedpherd Component Interconnect,周边元件扩展接口)的扩展插槽,其颜色一般为乳白色,位于主板上AGP插槽的下方,ISA插槽的上方。其位宽为32位或64位,工作频率为33MHz,最大数据传输率为133MB/sec(32位)和266MB/sec(64位)。可插接显卡、声卡、网卡、内置Modem、内置ADSL Modem、USB2.0卡、IEEE1394卡、IDE接口卡、RAID卡、电视卡、视频采集卡以及其它种类繁多的扩展卡。PCI插槽是主板的主要扩展插槽,通过插接不同的扩展卡可以获得目前电脑能实现的几乎所有外接功能。 AGP是Accelerated Graphics Port(图形加速端口)的缩写,是显示卡的专用扩展插槽,它是在PCI图形接口的基础上发展而来的。AGP规范是英特尔公司解决电脑处理(主要是显示)3D图形能力差的问题而出台的。AGP并不是一种总线,而是一种接口方式。随着3D游戏做得越来越复杂,使用了大量的3D特效和纹理,使原来传输速率为133MB/sec的PCI总线越来越不堪重负,籍此原因Intel才推出了拥有高带宽的AGP接口。这是一种与PCI总线迥然不同的图形接口,它完全独立于PCI总线之外,直接把显卡与主板控制芯片联在一起,使得3D图形数据省略了越过PCI总线的过程,从而很好地解决了低带宽PCI接口造成的系统瓶颈问题。可以说,AGP代替PCI成为新的图形端口是技术发展的必然。2023-07-19 15:11:181

老外说的hack是什么意思?
hack严意来说是hacks,也就是精通计算机的各种技术,能够发现漏洞和改良漏洞的技术人员。可如今的黑客,分很多类型,有的专攻违法犯罪的,有的专攻安全的。有点能够从自己精通的地方实现创造出利于我们现在生活的东西,而有的会试图入侵服务器,系统,行业,获取不正当的利益。相关介绍:黑客是一个中文词语,皆源自英文hacker,随着灰鸽子的出现,灰鸽子成为了很多假借黑客名义控制他人电脑的黑客技术,于是出现了“骇客”与"黑客"分家。2012年电影频道节目中心出品的电影《骇客(Hacker) 》也已经开始使用骇客一词,显示出中文使用习惯的趋同。实际上,黑客(或骇客)与英文原文Hacker、Cracker等含义不能够达到完全对译,这是中英文语言词汇各自发展中形成的差异。Hacker一词,最初曾指热心于计算机技术、水平高超的电脑高手,尤其是程序设计人员,逐渐区分为白帽、灰帽、黑帽等,其中黑帽(black hat)实际就是cracker。在媒体报道中,黑客一词常指那些软件骇客(software cracker),而与黑客(黑帽子)相对的则是白帽子。2023-07-19 15:11:031
