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
学术英语理工类 text15 和 text 18 的课文翻译
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

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

有谁知道在IC封装中,不同的芯片为什么有着不同的封装形式?那些封装形式是怎么来的?
IC就是半导体元件产品的统称,包括: 1.集成电路(integratedcircuit,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. 一、世界集成电路产业结构的变化及其发展历程 自1958年美国德克萨斯仪器公司(TI)发明集成电路(IC)后,随着硅平面技术的发展,二十世纪六十年代先后发明了双极型和MOS型两种重要的集成电路,它标志着由电子管和晶体管制造电子整机的时代发生了量和质的飞跃,创造了一个前所未有的具有极强渗透力和旺盛生命力的新兴产业集成电路产业。 回顾集成电路的发展历程,我们可以看到,自发明集成电路至今40多年以来,"从电路集成到系统集成"这句话是对IC产品从小规模集成电路(SSI)到今天特大规模集成电路(ULSI)发展过程的最好总结,即整个集成电路产品的发展经历了从传统的板上系统(System-on-board)到片上系统(System-on-a-chip)的过程。在这历史过程中,世界IC产业为适应技术的发展和市场的需求,其产业结构经历了三次变革。 第一次变革:以加工制造为主导的IC产业发展的初级阶段。 70年代,集成电路的主流产品是微处理器、存储器以及标准通用逻辑电路。这一时期IC制造商(IDM)在IC市场中充当主要角色,IC设计只作为附属部门而存在。这时的IC设计和半导体工艺密切相关。IC设计主要以人工为主,CAD系统仅作为数据处理和图形编程之用。IC产业仅处在以生产为导向的初级阶段。 第二次变革:Foundry公司与IC设计公司的崛起。 80年代,集成电路的主流产品为微处理器(MPU)、微控制器(MCU)及专用IC(ASIC)。这时,无生产线的IC设计公司(Fabless)与标准工艺加工线(Foundry)相结合的方式开始成为集成电路产业发展的新模式。 随着微处理器和PC机的广泛应用和普及(特别是在通信、工业控制、消费电子等领域),IC产业已开始进入以客户为导向的阶段。一方面标准化功能的IC已难以满足整机客户对系统成本、可靠性等要求,同时整机客户则要求不断增加IC的集成度,提高保密性,减小芯片面积使系统的体积缩小,降低成本,提高产品的性能价格比,从而增强产品的竞争力,得到更多的市场份额和更丰厚的利润;另一方面,由于IC微细加工技术的进步,软件的硬件化已成为可能,为了改善系统的速度和简化程序,故各种硬件结构的ASIC如门阵列、可编程逻辑器件(包括FPGA)、标准单元、全定制电路等应运而生,其比例在整个IC销售额中1982年已占12%;其三是随着EDA工具(电子设计自动化工具)的发展,PCB设计方法引入IC设计之中,如库的概念、工艺模拟参数及其仿真概念等,设计开始进入抽象化阶段,使设计过程可以独立于生产工艺而存在。有远见的整机厂商和创业者包括风险投资基金(VC)看到ASIC的市场和发展前景,纷纷开始成立专业设计公司和IC设计部门,一种无生产线的集成电路设计公司(Fabless)或设计部门纷纷建立起来并得到迅速的发展。同时也带动了标准工艺加工线(Foundry)的崛起。全球第一个Foundry工厂是1987年成立的台湾积体电路公司,它的创始人张忠谋也被誉为"晶芯片加工之父"。 第三次变革:"四业分离"的IC产业 90年代,随着INTERNET的兴起,IC产业跨入以竞争为导向的高级阶段,国际竞争由原来的资源竞争、价格竞争转向人才知识竞争、密集资本竞争。以DRAM为中心来扩大设备投资的竞争方式已成为过去。如1990年,美国以Intel为代表,为抗争日本跃居世界半导体榜首之威胁,主动放弃DRAM市场,大搞CPU,对半导体工业作了重大结构调整,又重新夺回了世界半导体霸主地位。这使人们认识到,越来越庞大的集成电路产业体系并不有利于整个IC产业发展,"分"才能精,"整合"才成优势。于是,IC产业结构向高度专业化转化成为一种趋势,开始形成了设计业、制造业、封装业、测试业独立成行的局面(如下图所示),近年来,全球IC产业的发展越来越显示出这种结构的优势。如台湾IC业正是由于以中小企业为主,比较好地形成了高度分工的产业结构,故自1996年,受亚洲经济危机的波及,全球半导体产业出现生产过剩、效益下滑,而IC设计业却获得持续的增长。 特别是96、97、98年持续三年的DRAM的跌价、MPU的下滑,世界半导体工业的增长速度已远达不到从前17%的增长值,若再依靠高投入提升技术,追求大尺寸硅片、追求微细加工,从大生产中来降低成本,推动其增长,将难以为继。而IC设计企业更接近市场和了解市场,通过创新开发出高附加值的产品,直接推动着电子系统的更新换代;同时,在创新中获取利润,在快速、协调发展的基础上积累资本,带动半导体设备的更新和新的投入;IC设计业作为集成电路产业的"龙头",为整个集成电路产业的增长注入了新的动力和活力。 二、IC的分类 IC按功能可分为:数字IC、模拟IC、微波IC及其他IC,其中,数字IC是近年来应用最广、发展最快的IC品种。数字IC就是传递、加工、处理数字信号的IC,可分为通用数字IC和专用数字IC。 通用IC:是指那些用户多、使用领域广泛、标准型的电路,如存储器(DRAM)、微处理器(MPU)及微控制器(MCU)等,反映了数字IC的现状和水平。 专用IC(ASIC):是指为特定的用户、某种专门或特别的用途而设计的电路。 目前,集成电路产品有以下几种设计、生产、销售模式。 1.IC制造商(IDM)自行设计,由自己的生产线加工、封装,测试后的成品芯片自行销售。 2.IC设计公司(Fabless)与标准工艺加工线(Foundry)相结合的方式。设计公司将所设计芯片最终的物理版图交给Foundry加工制造,同样,封装测试也委托专业厂家完成,最后的成品芯片作为IC设计公司的产品而自行销售。打个比方,Fabless相当于作者和出版商,而Foundry相当于印刷厂,起到产业"龙头"作用的应该是前者。2023-07-19 15:12:521
