混合性策略。在一些冲突中，任何规律性的行为都会被对手发觉并利用。因而，通过采取混合性策略来迷惑对手就显的非常重要。我们可以从体育运动中找到一些典型的例子，比如足球运动中的特定情况下选择跑位还是传球，网球比赛中选择击打近网球还是底线球，博弈论都为提高洞察力和掌握混合性策略恰当的火候提供了参考。
战略性行动。博弈者可以通过运用威吓和许诺来改变其他对手对其行动的预测，从而诱使他们采取对其有利的行为或改变他们对己不利的行为。为了取得成功，威吓和许诺必须是可信的。这往往会导致出现一些问题，原因就在于当需要采取以上策略时，通常实施威吓和许诺而获益往往会付出较大的代价。博弈论研究几种提高可信度的方法，一个基本的原则就是威吓和许诺要在符合博弈者利益的前提下减少自身未来行动的自由度。通过这样的方式，博弈者可以避免自己违背承诺，或者避免产生对对手冒犯的纵容。

科技英语阅读课后参考答案-Unit1,3
科技英语阅读课后参考答案-Unit1,3Unit 1 MathematicsPart I EST Reading Reading 1Warm-up Questions: Work in pairs and discuss the following questions. 1. Who is Bertrand Russell? Bertrand Arthur William Russell (b.1872 – d.1970) was a British philosopher, logician, essayist and social critic best known for his work in mathematical logic and analytic philosophy. His most influential contributions include his defense of logicism (the view that mathematics is in some important sense reducible to logic), his refining of the predicate calculus introduced by Gottlob Frege (which still forms the basis of most contemporary logic), his defense of neutral monism (the view that the world consists of just one type of substance that is neither exclusively mental nor exclusively physical), and his theories of definite descriptions and logical atomism. Russell is generally recognized as one of the founders of modern analytic philosophy, and is regularly credited with being one of the most important logicians of the twentieth century. 2. What is Russell’s Paradox? Russell discovered the paradox that bears his name in 1901, while working on his Principles of Mathematics (1903). The paradox arises in connection with the set of all sets that are not members of themselves. Such a set, if it exists, will be a member of itself if and only if it is not a member of itself. The paradox is significant since, using classical logic, all sentences are entailed by a contradiction. Russell's discovery thus prompted a large amount of work in logic, set theory, and the philosophy and foundations of mathematics. 3. What effect did Russell’s Paradox have on Gottlob Fregg’s system? At first Frege observed that the consequences of Russell’s paradox are not immediately clear. For example, “Is it always permissible to speak of the extension of a concept, of a class? And if not, how do we recognize the exceptional cases? Can we always infer from the extension of one concept’s coinciding with that of a second, that every object which falls under the first concept also falls under the second? Because of these kinds of worries, Frege eventually felt forced to abandon many of his views. 4. What is Russell’s response to the paradox? Russell's own response to the paradox came with the development of his theory of types in 1903. It was clear to Russell that some restrictions needed to be placed upon the original comprehension (or abstraction) axiom of naive set theory, the axiom that formalizes the intuition that any coherent condition may be used to determine a set (or class). Russell's basic idea was that reference to sets such as the set of all sets that are not members of themselves could be avoided by arranging all sentences into a hierarchy, beginning with sentences about individuals at the lowest level, sentences about sets of individuals at the next lowest level,1sentences about sets of sets of individuals at the next lowest level, and so on Using a vicious circle principle similar to that adopted by the mathematician Henri Poincaré, and his own so-called "no class" theory of classes, Russell was able to explain why the unrestricted comprehension axiom fails: propositional functions, such as the function "x is a set," may not be applied to themselves since self-application would involve a vicious circle. On Russell's view, all objects for which a given condition (or predicate) holds must be at the same level or of the same "type." 5. Have you ever heard of Zermelo-Fraenkel set theory.? Can you give an account of it? Contradictions like Russell’s paradox arose from what was later called the unrestricted comprehension principle: the assumption that, for any property p, there is a set that contains all and only those sets that have p. In Zermelo’s system, the comprehension principle is eliminated in favour of several much more restrictive axioms: a. Axiom of extensionality. If two sets have the same members, then they are identical. b. Axiom of elementary sets. There exists a set with no members: the null, or empty, set. For any two objects a and b, there exists a set (unit set) having as its only member a, as well as a set having as its only members a and b. c. Axiom of separation. For any well-formed property p and any set S, there is a set, S1, containing all and only the members of S that have this property. That is, already existing sets can be partitioned or separated into parts by well-formed properties. d. Power-set axiom. If S is a set, then there exists a set, S1, that contains all and only the subsets of S. e. Union axiom. If S is a set (of sets), then there is a set containing all and only the membersof the sets contained in S. f. Axiom of choice. If S is a nonempty set containing sets no two of which have common members, then there exists a set that contains exactly one member from each member of S. g. Axiom of infinity. There exists at least one set that contains an infinite number of members. With the exception of (b), all these axioms allow new sets to be constructed from already-constructed sets by carefully constrained operations; the method embodies what has come to be known as the “iterative” conception of a set. /doc/a90df7ed551810a6f524860e.html/entries/russell/ Section C Post-reading TaskReading Comprehension1. Directions: Work on your own and fill in the blanks with the main idea. Part 1 (Para. 1): Brief introduction to Russell’s paradox Part 2 (Paras. 2-5): The effect of Russell’s paradox on Gottlob Frege’s system.2Para. 2: Russell’s paradox dealt a heavy blow to Frege’s attempts to develop a foundation for all of mathematics using symbolic logic. Para. 3: An illustration of Russell’s paradox in terms of sets Para. 4: Contradiction found in the set. Para. 5: Frege noticed the devastating effect of Russell’s paradox on his system and inability to solve it.

Part 4 (Para. 9): Correspondence between Russell and Frege on the paradox 2. Directions: Work in pairs and discuss the following questions. 1) What is the basic idea of Russell’s paradox? 2) How to explain Russell’s paradox in terms of sets? 3) Can you explain the contradiction found in the sets related to Russell’s paradox 4) Is Russell’s own response to the paradox workable? 5) Do you know Zermelo-Fraenkel set theory? (open) 3. Directions: Read the following passage carefully and fill in the blanks with the words you’ve learned in the text. Russell's own response to the paradox came with the development of his theory of types in 1903. It was clear to Russell that some restrictions needed to be placed upon the original comprehension (or abstraction) axiom of naive set theory, the axiom that formalizes the intuition that any coherent condition may be used to determine a set (or class). Russell's basic idea was that reference to sets such as the set of all sets that are not members of themselves could be avoided by arranging all sentences into a hierarchy, beginning with sentences about individuals at the lowest level, sentences about sets of individuals at the next lowest level, sentences about sets of sets of individuals at the next lowest level, and so on. Using a vicious circle principle similar to that adopted by the mathematician Henri Poincaré, and his own so-called "no class" theory of classes, Russell was able to explain why the unrestricted comprehension axiom fails: propositional functions, such as the function "x is a set," may not be applied to themselves since self-application would involve a vicious circle. On Russell's view, all objects for which a given condition (or predicate) holds must be at the same level or of the same "type."Vocabulary and Structure31.

Use each word once. discover— (suffix) logic— (suffix) correspond—(suffix) describe—(suffix) contradict— (suffix) symbol—(suffix) form—(suffix) develop—(suffix) able—(prefix) equal—(suffix)1) The math may not have been new, but Duchin enjoyed the process of_________, and she got to work collaboratively with half a dozen other math whizzes.( discovery) 2) Packages can be sealed and can contain personal _________if it relates to the contents of the package.( correspondence) 3) New research indicates that the brain region may prefer_________ notation to other numeric representations .( symbolic) 4) To do this, an ideal model based on the _________ paradigm was constructed and then compared with a neutral model reflecting the further education system as it existed before the Act took effect.( equality) 5) Is this not in flagrant _________to Einstein's rule that signals do not travel faster than the velocity of light?( contradiction) 6) Sequential organization has the major advantage that the records are stored in a _________ order, presumably that sequence to which the records are normally required for printing and for soft copy reports.( logical) 7) The mathematical _________ of a zero-sum two-person game is not difficult to construct, and determining the optimal strategies and the value of the game is computationally straightforward.( description) 8) The proof we now know required the_________ unknown in Fermat's time.( development) of an entire field of mathematics that was9) Williams adds that many courses in geometry, “the one high school class that demands _________ reasoning,” have already been “gutted” and are no longer proof-based.( formal) 10) The concept of total aircraft ownership will become increasingly important should the traditional trade structure be _________to cover the expanse of technologies economically.( unable) 2. Directions: Complete the sentences with the words given in the brackets. Change the form if necessary. 1) The key to unraveling such apparent paradoxes is to characterize the initial set of possibilities ("initial" meaning before you receive any extra information) and then to eliminate possibilities based on that extra information. (base) 42) Indeed, this separation of meaning is reflected by the definition of "weak" in the OALD, with a distinct sense reserved for its use when pertaining to that of solutions (definition) 3) The resulting radical pollution control programme outlined by Nixon, calling for a 90 per cent reduction in vehicle emissions by 1980, not only led to him being credited (albeit briefly) as policy initiator of an environmental clean-up but also provided him with the chance to deal a blow to one of his most important opponents in the 1972 elections, Edmund Muskie (blow) 4) Singapore's continuing investments in education and training has brought a tenfold increase in our pool of Information Technology professionals and the Singapore worker has been consistently rated by BERI as the world's best in terms of technical skills, attitude and productivity. (term) 5) In this work he was led to topology, a still new kind of mathematics related to geometry, and to the study of shapes (compact manifolds) of all dimensions. (lead) 6) If there is no allowable string which spans the whole graph, then we can search in the same way as described above, but wherever the required path does not exist in the tree, check if that position in the tree is flagged for end-of-word (way) 7) During the past century, steps forward in physics have often come in the form of newly found particles; in engineering, more complex devices; in astronomy, farther planets and stars; in biology, rarer genes; and in chemistry, more useful materials and medications. (form) 8) A second reason for measurements is the more theoretical, put by Love as " the discovery of numerical relations between the quantities that can be measured to serve as a basis for the inductive determination of the form of the intrinsic energy function. " (serve) 9) Thus the optimum conditions for coastal terrace development would seem to be areas with small tidal ranges. Finally, tidal range is an important factor in the generation of tidal currents which may locally become of geomorphological importance (become) 10) The original double entrance doors to the booking hall had been replaced by an utterly incongruous picture window as had adjacent booking hall and waiting room windows. (replace) 3. Directions: Reorder the disordered parts of a sentence to make a complete sentence. 1) A simpleway to describe topology is as a 'rubber sheet geometry' — topologists study those properties of shapes that remain the same when the shapes are stretched or compressed. 2) Since the mid-1990s scientists have floated the idea that representations of numeric quantities, whether expressed as digits or as written words, are codified by the parietal cortex, a higher-processing region in the brain located just above the forehead. 3) As activity was monitored, located just above the forehead ,researchers noted changes under the assumption that the brain reduces activity as it becomes accustomed to a stimulus and then reactivates when a novel stimulus is presented. 4) That has not stopped physicists from devising new algorithms for the devices, which can calculate a lot faster than ordinary computers—in fact, exponentially faster, in quite a literal5sense. 5) Such a device would be made of metamaterial, a thicket of metal rings or other shapes that bends light in funny ways. 4. Directions: Change the following sentences into nominalized ones. 1) The passage of night could be marked by the appearance of 18 of these stars. 2) The full proof of Fermat's Last Theorem is contained in these two papers. 3) The concept of fixed-length hours, however, did not originate until the Hellenistic period. 4) There is a probability that my first sock is red because only one of the remaining three socks is red. 5) The importance of accurate data in quantitative modeling is central to using Bayes's theorem to calculate the probability of the existence of God.Discourse Understanding1. C. A "3 percent margin of error" means that there is a 95 percent chance that the survey result will be within 3 percent of the population value.2. E. How is it that a survey of only 1,000 people can reach this level of accuracy?3. G. The margin of error depends inversely on the square root of the sample size.4. A. The margin of error is a mathematical abstraction, and there are a number of reasons why actual errors in surveys are larger.5. F. Finally, the 3 percent margin of error is an understatement because opinions change.Reading 2 (/doc/a90df7ed551810a6f524860e.html/article.cfm?id=mandelbrot-set-1990-hor gan) Section A Pre-reading TaskWarm-up Questions /doc/a90df7ed551810a6f524860e.html/article.cfm?id=mandelbrot-set-1990 1. Who discovered the Mandelbrot set? This is not a trick question, not easy to answer. Many people including Mandelbrot have laid claim to the discovery. 2. Why was the set named after Benoit B. Mandelbrot? The set is named after Benoit B. Mandelbrot, a mathematician at the IBM Thomas J. Watson Research Center because he coined the term fractal to describe phenomena (such as coastlines, snowflakes, mountains and trees) whose patterns repeat themselves at smaller and smaller scales. 3. Why has there been so much controversy about who discovered the Mandelbrot set?6Mandelbrot claims that he and he alone discovered the Mandelbrot set, but there are other mathematicians who have challenged his claim. 4. What did the challengers say about Mandelbrot’s claim of discovery? Two mathematicians said that they independently discovered and described the set at about the same time as Mandelbrot did. And another mathematician also asserted that his work on the set not only predated Mandelbrot's efforts but also helped to guide them 5. Why did some professors support Mandelbrot’s claim? Mandelbrot deserves to have the set named after him, because his efforts brought the set to the attention of both the public and of the pure-mathematics community.Section C Post-reading TaskReading and Understanding1. Choose the best summary of the passage. C A B D2. Complete the sentences based on the text. 1) The term Mandelbrot set is used to refer both to a general class of_________________ and to a particular instance of such a set. （fractal sets） 2) 2.In general, a Mandelbrot set marks the set of points in the _________________ such that the corresponding Julia set is connected and not computable. （complex plane） 3) "The" Mandelbrot set is the set obtained from the _________________ z_(n+1)==z_n︿2+c with z_0==c, where points in the complex plane for which the orbit of z_n tend to infinity are in the set. （quadratic recurrence equation） does not4) Setting z_0 equal to any point in the set that is not a _________________ gives the same result. （periodic point） 5) The Mandelbrot set was originally called a _________________ by Mandelbrot. J. Hubbard and A. Douady proved that the Mandelbrot set is connected（ molecule） /doc/a90df7ed551810a6f524860e.html/11901033_d.html Language in Use1. Match the Chinese in the left column with the English in the right column. 迭代函数 iterative function 优先权之争 priority battle 分形特征 fractal properties7有意义 make sense 以越来越⼩的规模重复同⼀模式 patterns repeat themselves at smaller and smaller scales 混沌理论chaos theory 季刊 a quarterly journal 数学界 the mathematics community 波纹线 crisp lines 会议公报 proceedings of a conference 2. Join the following short sentences into longer ones. e.g. a. A fractal is generally a rough or fragmented geometric shape . b. The shape can be subdivided in parts. c. each part is (at least approximately) a reduced-size copy of the whole, a property called d. each part has a property of self-similarity. e.g. A fractal is generally "a rough or fragmentedgeometric shape that can be subdivided in parts, each of which is (at least approximately) a reduced-size copy of the whole", a property called self-similarity. 1) In addition to coining the term "fractal" to describe objects and surfaces which are irregular at various dimensions of scale, he also introduced such concepts as "fractal dimensions" and the particular fractal known as the Mandelbrot set, frequently represented with the mathematical formula z → z2 + c. 2) It appeared that things were settling into a pleasant and fruitful routine, with his school lessons supplemented by long talks with his uncle about classical analysis, the iterative work of Pierre Fatou and the equally fascinating Julia Sets generated by Gaston Julia 3) Just as the youthful Mandelbrot had passed his college entrance exams by translating algebraic problems into geometrical problems, and solving them by intuitively deducing the "perfected" shape, he here realized there was something deeper, something mathematical, behind these strange patterns. 4) But the beauty in Mandelbrot's models was not that they generated a deceitful randomness, but that they could generate graphed data whose visual pattern accurately mimicked the visual patterns created by real phenomena。

科技英语课后答案
科技英语课后答案第一章科技英语阅读第一节科技英语主要特点I.1.The first three sentences in Passage One are all constructed with passive voicewhile the first three sentences in Passage Two are constructed with active voice. Therefore, the language in Passage One sounds more formal and objective than that of Passage Two.2.The words spoken by Sheila in Passage Two are informal. Examples: "There'sRavi at the home of that American doctor." (Contracted form); "A wonderful guy." (Incomplete sentence); "Ravi looks sweet, doesn 't he?" (Question tag).3.In the second paragraph of Passage One, "it" refers to "to use insecticideregularly, on a very large scale."4.In the second paragraph of Passage Two, "through" means "finish" or"complete."5.Passage One is written for academic purpose and Passage Two mainly forentertainment.II.Passage OneA blast of hot air is sent into the bottom of the furnace to make the coke burn fiercely. It is blown into the furnace through pipes. These pipes are installed around the circumference of the blast furnace eight feet above the bottom.While the coke is burning and iron is melting, gas is formed at the top of the chamber. This is led off from the top of the furnace to be used. It contains carbon monoxide, which is combustible. Part of this gas is used for making the air blast hot. It is led off into stoves.Passage TwoAll elements are composed of discrete units called atoms, which are the smallest particles that exhibit the characteristics of the element. Atoms are tiny units of matter composed of positively charged protons, negatively charged electrons, and electrically neutral neutrons. Protons and neutrons, which have approximately the same mass, are clustered in the nucleus in the center of the atom. Electrons, which are tiny in comparison to the other units, orbit the nucleus at high speed. Atoms that have an equal number of electrons and protons are electrically neutral. Those that have gained or lost electrons, and therefore are positively or negatively charged, are called ions.第二节科技、半科技英语专业术语I.1. D (自动驾驶仪)2. F (生物钟)3. I (热核的)4. G (地热的)5. B (微波)6. J (放射疗法)7.
