A recent study of important inventions made since the turn of the century reveals that more than half were the product of individual invent-ors working alone, independent of organized industrial research. While industrial laboratories contributed such important products as nylon and transistors, independent inventors developed air conditioning, the automatic transmission, the jet engine, the helicopterminsulin, and streptomycin. Still other inventions, such as stainless steel, television, silicons, and plexiglass were developed through the combined efforts of individuals and laboratory teams.Despite these findings, we are urged to support monopoly power on the grounds that such power creates an environment supportive of innovation. We are told that the independent inventor, along with the small firm, cannot afford to undertake the important research needed to improve our standard of living while protecting our diminishing resources; that only the prodigious assets of the giant corporation or conglomerate can afford the kind of expenditures that can produce the technological advances vital to economic progress. But when we examine expenditures for research, we find that of the more than $ 35 billion spent each year in this country, almost two-thirds is spent by the federal government. More than half of this government expenditure is funneled into military research and product development, accounting for the enormous increase in spending in such industries as nuclear energy, aircraft, missiles, and electronics. There are those who consider it questionable that these defense-linked research projects will account for an improvement in the standard of living or, alternately, do much to protect our diminishing resources. Recent history has demonstrated that we may have to alter our longstanding conception of the process actuated by competition. The price variable, once perceived as the dominant aspect of the competitive process is now subordinate to the competition of the new product, the new business structure, and the new technology. While it can be assumed that in a highly competitive industry not dominated by a single corporation, investment in innovation--a risky and expensive budget item--might meet resistance from management and stockholders who might be more concerned with cost-cutting, efficient organization, and large advertising budgets, it would be an egregious error to assume that the monopolistic producer should be equated with bountiful expenditures for research. Large-scale enterprises tend to operate more comfortably in stable and secure circumstances, and their managerial bureaucracies tend to promote the status quo and resist the threat implicit in change. Furthermore, the firm with a small share of the market will aggressively pursue new techniques and different products, since with little vested interest in capital equipment or plant it is not deterred from in-vestment in innovation. In some cases, where inter-industrycompetition is reduced or even entirely eliminated, the industrial giants may seek to avoid capital loss resulting from obsolescence by deliberately obstructing technological progress.The conglomerates are not, however, completely exempt from strong competitive pressures; there are instances in which they, too, must compete, as against another industrial Goliath, and then their weapons may include large expenditures for innovation.16. According to the passage, important inventions of the twentieth century ________.A. are not necessarily produced as a result of governmental support for military weapons research and development.B. came primarily from the huge laboratories of monopoly industries.C. were produced at least as frequently by independent inventors as by research teams.D. have greater impact on smaller firms than on conglomerates.17. It is the author"s belief, as expressed or implied in the passage, that________.A. monopoly power creates an environment supportive of innovation.B. governmental protection for military research will do much to protect our dwindling resources.C. industrial giants, with their managerial bureaucracies, respond more quickly to technological change.D. firms with a small share of the market will aggressively pursue innovations because they are not locked into old capital equipment.18. Management and stockholders might be deeply concerned with cost cutting rather than innovation if _______.A. their company is faced with strong competition in a field not dominated by one of the industrial giants.B. they are very stable and secure and hold a monopoly position in their industry.C. they are part of the military-industrial complex and are the recipients of federal funds for product development.D. they have produced some of the important inventions of this century.19. Which of the following statements is neither expressed nor implied in the passage?A. Important inventions have been produced, in the past, by individuals as well as by corporate teams.B. The federal government"s research funds are funneled into pure research as well as military research.C. The development of the automatic transmission is not credited to organized industrial research.D. Industrial giants may deliberately suppress innovations to avoid capital loss resulting from obsolescence.20. The author"s purpose in this passage is to____.A. advocate an increase in governmental support of organized industrial research.B. point out a common misconception about the relationship between the extent of industrial research and the growth of monopolistic power in industry.C. describe the inadequacies of small firms in dealing with the important matter of research and innovation.D. show that America"s strength depends upon individual ingenuity and resourcefulness.III Translation from English into Chinese (20%)Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a deep ocean of anguish, reaching to the verge of despair.I have sought love, first, because it brings ecstasy---ecstasy so great that I would often have sacrificed all the rest of life for a few hours of this joy. I have sought it, next, because it relieves loneliness that terrible loneliness in which one shivering consciousness looks over the rim of the world into the cold unfathomable lifeless abyss. I have sought it, finally, because in the union of love I have seen, in a mystic miniature, the prefiguring vision of the heaven that saints and poets have imagined. This is what I sought, and though it might seem too good for human life, this is what at last I have found.With equal passion I have sought knowledge. I have wished to understand the hearts of men. I have wished to know why the stars shine. A little of this, but not much, I have achieved.Love and knowledge, so far as they were possible, led upward reward the heavens(这句话似乎不完整). But always pity brought me back to earth. Echoes of cries of pain reverberated in my heart. Children in famine, victims tortured by oppressors, helpless old people a haled burden to their sons, and the whole world of loneliness, poverty, and pain make a mockery of what human life should be. I long to alleviate the evil, but I cannot, and I too suffer.This has been my life. I have found it worth living, and I would gladly live it again if the chance were offered to me.有三种简单却强烈的情感支配着我的生活,它们分别是:对爱的渴望,对知识的探求,以及对人类的苦难不可抑制的怜悯。

2007博士学位研究生入学考试试题-综合解释答案

2007博士学位研究生入学考试试题-综合解释答案

标准答案(要点)一、1、由于含氢指数低,天然气层中天然气对快中子的减速能力低于骨架,导致中子测井结果明显低于实际的孔隙度的一种物理现象。

2、传统的声速测井往往采用阈值检测法来判断首波的到达。

如果地层对声波的衰减太大,以至于使首波的幅度小于所设置的阈值,则不能检测到首波,而只能检测到后续波,这会使所测量的声波旅行时间变大,这种现象叫“周波跳跃”。

周波跳跃一般都发生在远波,使时差t 变大。

周波跳跃现象的产生导致时间测量误差为首波的若干个周期。

3、淡水泥浆滤液侵入条件下,含高矿化度地层水轻质油气层中的油气相对渗透率大于水相相对渗透率,导致在侵入带前缘形成的以原生高矿化度地层水相对富集的环带。

4、核磁测井三种横向弛豫机制之一。

发生在岩石孔隙中固体与流体界面。

表面弛豫取决于岩石孔隙表面弛豫率和孔隙比表面。

5、在给定的地区地质条件下,为了完成预定的勘探、开发或工程任务而选用的一套经济实用的综合测井方法。

岩性、物性、流体性质。

6、饱和多相流体孔隙介质中一相流体有效渗透率与绝对(空气)渗透率的比值。

二、1、根据岩石物理体积模型,采用反演理论进行解释的一种方法。

以经过环境校正后的测井值(向量)为基础,根据适当的解释模型和测井响应方程,计算理论测井值(向量),并与实际测井值(向量)对比,按非线性加权最小二乘原理建立目标函数,用最优化方法不断调整未知储层参数,使目标函数达到极小值(能结合公式叙述最佳)。

2、是油藏描述和多井评价中的一项技术。

选择有系统连续取心、测试和较全测井系列等资料齐全的井,建立可以应用于整个油藏(田)其他井的测井解释模型、参数。

3、测井资料综合分析的一种直观图形手段。

如中子—密度测井重叠图可以直观反映地层岩性类型以及孔隙度高低;视地层水电阻率曲线与深探测电阻率曲线可以帮助判断储层流体性质等。

三、1、低电阻率油气层指与同等物性、岩性和水性的水层,电阻增大率小于2-3的油气层,主要类型有:具有高—极高地层水矿化度的低电阻率油气层,引起这类油气层呈低电阻率的原因是矿化度极高的地层水在孔隙中形成密布的导电网络,使油气层电阻率明显降低;微孔隙发育的低电阻率油气层,这类油气层低电阻率的原因是岩石的颗粒较细(细粉砂和粘土矿物),导致地层中微孔隙十分发育,微孔隙和渗流孔隙并存,再加上地层水矿化度的影响,其电阻率值可能极低;富含泥质的低电阻率油气层,这类地层往往是淡水泥质砂岩地层,这时泥质的附加导电性表现十分突出,成为引起电阻率下降的原因;粒间孔隙与裂缝并存引起的低电阻率油气层,由于裂缝发育,在钻井过程中有相当的泥浆滤液侵入,驱赶并代替了裂缝中的油气,而使油气层的电阻率明显下降; 表面和骨架导电引起的低电阻率油气层 2、(1)岩石体积模型方法的基本要点是:按物理性质的差别,将岩石分成几个组成部分,而且岩石的总体积等于各部分体积之和;根据测井方法的物理意义,表达出宏观物理量与测量的物理量(单位物理量)的表达式;对表达式简化得到体积模型方程。

Reading Comprehension (50%)Direction: For each of the following passages there are five questions or unfinished is followed by five statements. For each of them there are four choices, choose the best one to answer the question or complete the statement.Passage 1In managing information resources, the medium may be the key to an effective system. The medium is a vehicle, a tool, or a container for holding information; the information itself is the thing of value.There popular categories of information media are paper, film, and electronic system. The media choice must not be viewed as a choice among these three, however, it must be viewed as an opportunity to select from a multitude of media possibilities in combinations, that build effective systems. In many instances the person responsible for information-resource management is not the person who determines the medium in which information will be created. In such a case, the manager of a firm's information resources faces a challenge in making a significant contribution to the organization's objectives.For effective management of information resources, media conversion may be necessary. examples include keying or scanning paper documents to convert them to electronic media. Other processes convert electronic media from one format to another. For example, disk files created on one system may not be compatible with another system. Various hardware and software combinations can be used to convert files to formats that equipment will accept. For information generated within organizations, this necessity of making systems compatible may be eliminated by cooperative planning. However, very little control can be exercised over the media used to generate information that comes to your organization from the outside.The medium for information may be selected to satisfy. a need that excite when information is created and communicated. For example, a paper record may be created because of its portability and because no special equipment is necessary for later references to that information; electronic transmission may be selected because it is the fastest means of communicating information. A firm may use electronic mail because a network already exists for on-line computercommunication. The additional application may cost less than postage to mail paper memos.21. Which of the following can best sum up the passage?A. Media Selection in Managing Information Resources.B. The Importance and Necessity of Media ConversionC. Three Categories of Information Media.D. Various Means of Communicating Information22. The first paragraph aims telling the reader ______.A. the importance of information resources managementB. the relationship between the medium and informationC. the great variety of media for holding informationD. the numerous resources of information23. According to the author, ______.A. paper is the best storage deviceB. people have three choices in selecting information mediaC. it is better to let the person responsible for information-resource management determine the mediumD. the manager should build an effective system by selecting a good combination of different media24. For effective management of information resources, the manager should ______.A. convert all paper documents to electronic mediaB. make media conversion when necessaryC. control the media used to generate information both inside and outside his organizationD. use one format in processing information25. The main idea of the last paragraph is ______.A. paper record is the most convenient medium for later referenceB. electronic mail costs less than postage to mail paper memosC. different media for information may be selected for different purposesD. by using different media, a firm can create various in formation for its objectives Passage 2"digital, digital, digital" continues to grow in volume worldwide. Digital ofchantThecameras, digital video camcorders, video CD players, DVD, cellular phones, and a host of computer peripherals are moving the trend along at a breathtaking rate. For the average person, it may seem like a remote and puzzling phenomenon meant only for the technologically adept.Virtually every aspect of our lives could be affected by the digital revolution. Here is a hypothetical scenario to show the possibilities: A real estate agent in Seattle uses a digital still camera to take some pictures of a house she's trying to sell., She transfers them to her computer, digitally retouches and enhances them, and posts them on her company's Internet Web site. In Singapore, a buyer sees the pictures and asks via electronic mail for more information. The agent replies via e-mail and attaches the text and a digital video clip to her message. Later the buyer flies to Seattle, inspects the property, and seals the deal.One of the biggest marketing surprises of the current age is the digital still camera. Once prohibitively expensive, these cameras have radically dropped in price while gaining in resolutionand other features. Although they often resemble traditional cameras, they don't use film. Instead, they store images on either a small removable memory card or on the memory chip inside the camera.The beauty of digital photography is that while you'll spend relatively more for a digital camera, you'll save a lot on film processing costs, because there aren't any. You can also discard digital pictures and keep shooting. Better yet, you can use software to enhance or alter the image. In quality, the images consumer-level digital cameras produce do not compare to ones you'd get from a 35mm camera. For the most part, though, digital photos are meant to be viewed on a computer monitor, and so their resolution is more than acceptable. In a world where the speed at which you distribute information often means the difference between success and failure, and immediacy supersedes quality in importance, may people are finding a use for digital camera.26. From the first paragraph we know the average person thinks ____.A. the digital age is far awayB. digital is too complicated for himC. digital age is dreadfulD. both a and b27. In the second paragraph the writer used an example to show that _____.A. any real estate agent should use digital still cameraB. digital still camera should be used together with Internet WebC. digital age is gaining momentumD. house dealing can be made easier28. _____ could be the best summary of the last two paragraphs.A. Digital still camera and traditional cameraB. Pros and cons of digital still cameraC. Capturing the world digitallyD. The way to use digital still camera29. All the following are the advantages of digital still camera EXCEPT ______.A. no need of filmB. easy to carryC. the image can be changedD. high resolution30. Which of the following best summarizes the passage?A. New Digital Age of InteractivityB. Digital Still CameraC. One Application of ComputerD. Goodbye Analog, Hello DigitalPassage 3In the days immediately following hurricane Andrews deadly visit to South Florida, Allstate Insurance hastily dispatched more than 2,000 extra clang adjusters to the devastated area to assist the 200 stationed there. Many of the reserves rived in convoys of motor homes. Others flew in from as far away as Alaska and California. Since the storm had knocked out telephone lines, Allstate rushed to set up its own communications system. Allstate expects to pay out $1.2 billion to cover more than 121,000 damage claims as a result of Andrew.All told, U.S, property and casualty insurers have been hit with more than $8 billion in Andrew-related claims, making the hurricane the most costly single calamity to strike the industry since the San Francisco earthquake and fire in 1906 ( cost: $6 billion, after inflation). With claims continuing to pour in, Andrew threatens to take a painful toll on the already battered property-casualty insurance industry and its 100 million policy-holders. The final bill, analysts predict, is likely to top $10 billion. While most well-capitalized insurers are expected to weather the storm, less anchored firms are in danger of being blown away, leaving U.S. consumers stuck with the tab. Says Sean Mooney, senior researcher at the Insurance Information Institute: "It will take years before the industry digs itself out from the wreckage left by Andrew. Some (companies) will be buried by it?Hurricane Andrew is the latest in a string of mishaps to plague the American insurance industry this year. In April an over flowing Chicago River flooded the city's downtown district, costing insurers $300million in claims. A month later, Los Angles was rocked by the worst civilian riot in the U.S. since the Civil War. The insurance toll: $1 billion. Then came a series of major hailstorms in Texas. Florida and Kansas. They cost insurers a combined $700 million. And two weeks after Andrew, another lethal hurricane, Iniki, smashed into Hawaii, causing $ 1.4 billion in damages. In all, property and casualty insurers have paid out a record $13 billion in claims so far this year, far surpassing the previous high of $7.6 billion in 1989, the year of Hurricane Hugo and California's Bay Area earthquake. Just as in that year, when those catastrophes were followed by substantial increases in insurance premiums, insurers are already lobbying for rate relief.31. According to the passage. "Allstate Insurance"most likely refers to ____.A. one of the property and casualty insurers in the U.S.B. the only insurance company responsible for the damage claims by AndrewC. the insurance industry as a wholeD. the biggest insurance company in the U.S.32. As is stated in the second paragraph, the result of hurricane Andrew is likely to _______.A. lead to inflation throughout the U.S.B. make the largest insurers suffer the mostC. put the industry in South Florida out of actionD. cause insurers with insufficient funds to go bankrupt33. Using context clues, we may infer that "stuck with the tab"most probably means _____."caught in the hurricane"A."exposed to natural disasters"B."trapped in financial difficulties"C."extremely vulnerable to further damages"D.35. The main purpose of the passage is to _____.A. show the severe damages and heavy losses caused by Hurricane AndrewB. suggest that U.S. insurers are virtually unable to cover the damage claims any moreC. tell about the difficult situation faced by the insurers throughout the U.S.D. prove that disasters tend to cause ever worsening devastation as time goes on.Passage 4Steve Courtney wrote historical novels. Not, he was quick to explain, over colorful love stories of the kind that made so much money for so many women writer, but novels set, andcorrectly set, in historical periods. Whatever difference he saw in his own books, his readers didnot seem to notice it, and his readers were nearly all women. He had studied at university, but hehad not been a particularly good student, and he had never afterwards let any academic knowledgehe had gained interfere with his writing.Helen, his wife, who did not have a very high opinion of her husband's ability as a novelist,had been careful to say when she married him that she was not historically minded.Above all, Helen was doubtful whether her relationship with Steve would work at all in thevillage of Stretton, to which they had just moved. It was Steve who had wanted to move to thecountry, and she had been glad of the change, in principle, whatever doubts she was now havingabout Stretton as a choice. But she wondered whether Steve would not, before very long, wantto live in London again, and what she would do if he did. The Stretton house was not a weekendcottage. They had moved into it and given up the London flat altogether, partly at least, she suspected, because that she Steve's idea of what a successful author ought to do. However, she thought he was not going to feel like a successful author half as much in Stretton ashe had in London. On the other had, she supposed he might just start dashing up to London forthe day to see his agent or have lunch with his publisher, leaving her behind in Stretton, andshe thought on the whole she would like that.36. What was Steve's attitude towards women who wrote love stories?A. He would have liked to earn as much money as they did.B. He was afraid of being compared unfavorably with themC. He did not think he could write about the same subjectsD. He had a low opinion of the kind of books they wrote37. What did Helen have to be careful to hide?A. Her lack of interest in historyB. Her low opinion of her husband's writingC. Her dislike of her husband's writingD. Her inability to husband's admirers.38. What were Helen's feelings about the move from London to Stretton?A. She wanted to remain in the countryB. She had been unwilling to leave LondonC. She thought it was time to return to undon39. Helen thought Steve might not be content in Stretton because ______.A. he would not be able to write so well in the countryB. he would not feel so important in StrettonC. his relationship with Helen was changingD. he would not be lonely without all his London friends40. The passage as a whole suggests that Steve's novels were _____.A. popular but unimportantB. serious works of literatureC. admired for their historical truthD. written with women readers in mindPassage 5The sixties have been misunderstood. It was not a radical decade, as the term radical is commonly used in connection with those years. It was not a decade of the left ascendant. Rampant, perhaps but not ascendant. Rather, the decade was radical radicalizing, which, subsequent decades have shown, is different. Politically, the sixties invigorated the right more than the left. But of course politics is not everything. In fact, three decades down the road, the nation's political discourse may be driven by conservatives, but they, although by many measures triumphant, seem aggrieved because politics seems peripheral to, and largely impotent against, cultural forces and institutions permeated with what conservatives consider the sixties sensibilities.Treating a decade as a discrete entity obviously makes the assumption that history during that decade had an obliging tidiness, opening with a decisive and tone-setting episode and closing with a suitably climatic event. History rarely accommodates that assumption. Such a treatment of a decade also makes the equally dubious assumption that the decade in question had a clearly dominant tone or profile. So the 1920s was the decade of jazz., flappers, the birth of the sports celebrity (Babe Ruth, Red Grange, Jack Dempsey), the Lost Generation, Sacco and Vanzetti and ...Warren Harding, Calvin Coolidge, and Herbert Hoover.Let us stipulate this, then: A decade, even one as intensely felt at the time and as hotly debated afterward as the sixties was and is, can come to seem, when recollected in tranquility, quite unlike the decade as it was felt at the time, and unlike the decade as it is portrayed by people with an emotional or political investment in portraying it a particular way.It is arguable that we should think of the sixties as beginning in November 1963 and ending in October 1973. That is, the years we connect with the tumultuousness associated with the phrase "the sixties" began with the assassination of a president and ended with the Yom Kippur War and the energy crisis. The assassination shattered (or at least many people say it did ) the nation's sunny postwar disposition; it supposedly "ended American innocence." It is unclear how innocent was this nation that had been made possible by Puritans, had been founded by such innocents as Benjamin Franklin, John Adams, and James Madison, had been born in the bloodshed of what actually was not only the American Revolution but also America's first civil war, had been preserved by the worst civil war the world had until then seen...you get the picture.
