Although dependence and independence are properties of sets of elements, we also apply these terms to the elements themselves. For example, the elements in an independent set are called independent elements.虽然相关和无关是元素集的属性，我们也适用于这些元素本身。

例如，在一个独立设定的元素被称为独立元素。

If s is finite set, the foregoing definition agrees with that given in Chapter 8 for the space n V . However, the present definition is not restricted to finite sets.如果S 是有限集，同意上述定义与第8章中给出的空间n V ，然而，目前的定义不局限于有限集。

If a subset T of a set S is dependent, then S itself is dependent. This is logically equivalent to the statement that every subset of an independent set is independent.如果集合S 的子集T 是相关的，然后S 本身是相关的，这在逻辑上相当于每一个独立设置的子集是独立的语句。

If one element in S is a scalar multiple of another, then S is dependent. 如果S 中的一个元素是另一个集中的多个标量的，则S 是相关的。

If S ∈0,then S is dependent. 若S ∈0，则 S 是相关的。

2.4 整数、有理数与实数4－A Integers and rational numbersThere exist certain subsets of R which are distinguished because they have special properties not shared by all real numbers. In this section we shall discuss such subsets, the integers and the rational numbers.有一些R 的子集很著名，因为他们具有实数所不具备的特殊性质。

在本节我们将讨论这样的子集，整数集和有理数集。

To introduce the positive integers we begin with the number 1, whose existence is guaranteed by Axiom 4. The number 1+1 is denoted by 2, the number 2+1 by 3, and so on. The numbers 1,2,3,…, obtained in this way by repeated addition of 1 are all positive, and they are called the positive integers.我们从数字 1 开始介绍正整数，公理 4 保证了 1 的存在性。

1+1 用2 表示，2+1 用3 表示，以此类推，由 1 重复累加的方式得到的数字 1,2,3，…都是正的，它们被叫做正整数。

Strictly speaking, this description of the positive integers is not entirely complete because we have not explained in detail what we mean by the expressions “and so on”, or “repeated addition of 1”.严格地说，这种关于正整数的描述是不完整的，因为我们没有详细解释“等等”或者“1的重复累加”的含义。

数学专业英语－Differential CalculusHistorical IntroductionNewton and Leibniz,quite independently of one another,were largely responsible for developing the ideas of integral calculus to the point where hitherto insur mountable problems could be solved by more or less routine methods.The succ essful accomplishments of these men were primarily due to the fact that they were able to fuse together the integral calculus with the second main branch o f calculus,differential calculus.The central idea of differential calculus is the notion of derivative.Like the inte gral,the derivative originated from a problem in geometry—the problem of find ing the tangent line at a point of a curve.Unlile the integral,however,the deriva tive evolved very late in the history of mathematics.The concept was not form ulated until early in the 17th century when the French mathematician Pierre de Fermat,attempted to determine the maxima and minima of certain special func tions.Fermat’s idea,basically very simple,can be understood if we refer to a curve a nd assume that at each of its points this curve has a definite direction that ca n be described by a tangent line.Fermat noticed that at certain points where th e curve has a maximum or minimum,the tangent line must be horizontal.Thus t he problem of locating such extreme values is seen to depend on the solution of another problem,that of locating the horizontal tangents.This raises the more general question of determining the direction of the tange nt line at an arbitrary point of the curve.It was the attempt to solve this gener al problem that led Fermat to discover some of the rudimentary ideas underlyi ng the notion of derivative.At first sight there seems to be no connection whatever between the problem of finding the area of a region lying under a curve and the problem of findin g the tangent line at a point of a curve.The first person to realize that these t wo seemingly remote ideas are,in fact, rather intimately related appears to have been Newton’s teacher,Isaac Barrow(1630-1677).However,Newton and Leibniz were the first to understand the real importance of this relation and they explo ited it to the fullest,thus inaugurating an unprecedented era in the development of mathematics.Although the derivative was originally formulated to study the problem of tang ents,it was soon found that it also provides a way to calculate velocity and,mo re generally,the rate of change of a function.In the next section we shall consi der a special problem involving the calculation of a velocity.The solution of this problem contains all the essential fcatures of the derivative concept and may help to motivate the general definition of derivative which is given below.A Problem Involving VelocitySuppose a projectile is fired straight up from the ground with initial velocity o f 144 feet persecond.Neglect friction,and assume the projectile is influenced onl y by gravity so that it moves up and back along a straight line.Let f(t) denote the height in feet that the projectile attains t seconds after firing.If the force of gravity were not acting on it,the projectile would continue to move upward with a constant velocity,traveling a distance of 144 feet every second,and at ti me t we woule have f(t)=144 t.In actual practice,gravity causes the projectile t o slow down until its velocity decreases to zero and then it drops back to eart h.Physical experiments suggest that as the projectile is aloft,its height f(t) is gi ven by the formula(1)f(t)=144t –16 t2The term –16t2is due to the influence of gravity.Note that f(t)=0 when t=0 a nd when t=9.This means that the projectile returns to earth after 9 seconds and it is to be understood that formula (1) is valid only for 0<t<9.The problem we wish to consider is this:To determine the velocity of the proj ectile at each instant of its motion.Before we can understand this problem,we must decide on what is meant by the velocity at each instant.To do this,we int roduce first the notion of average velocity during a time interval,say from time t to time t+h.This is defined to be the quotient.Change in distance during time interval =f(t+h)-f(t)/hThis quotient,called a difference quotient,is a number which may be calculated whenever both t and t+h are in the interval[0,9].The number h may be positiv e or negative,but not zero.We shall keep t fixed and see what happens to the difference quotient as we take values of h with smaller and smaller absolute v alue.The limit process by which v(t) is obtained from the difference quotient is wri tten symbolically as follows:V(t)=lim(h→0)[f(t+h)-f(t)]/hThe equation is used to define velocity not only for this particular example bu t,more generally,for any particle moving along a straight line,provided the position function f is such that the differerce quotient tends to a definite limit as h approaches zero.The example describe in the foregoing section points the way to the introducti on of the concept of derivative.We begin with a function f defined at least on some open interval(a,b) on the x axis.Then we choose a fixed point in this in terval and introduce the difference quotient[f(x+h)-f(x)]/hwhere the number h,which may be positive or negative(but not zero),is such th at x+h also lies in(a,b).The numerator of this quotient measures the change in the function when x changes from x to x+h.The quotient itself is referred to a s the average rate of change of f in the interval joining x to x+h.Now we let h approach zero and see what happens to this quotient.If the quot ient.If the quotient approaches some definite values as a limit(which implies th at the limit is the same whether h approaches zero through positive values or through negative values),then this limit is called the derivative of f at x and is denoted by the symbol f’(x) (read as “f prime of x”).Thus the formal defi nition of f’(x) may be stated as follows:Definition of derivative.The derivative f’(x)is defined by the equationf’(x)=lim(h→o)[f(x+h)-f(x)]/hprovided the limit exists.The number f’(x) is also called the rate of change of f at x.In general,the limit process which produces f’(x) from f(x) gives a way of ob taining a new function f’from a given function f.This process is called differ entiation,and f’is called the first derivative of f.If f’,in turn,is defined on an interval,we can try to compute its first derivative,denoted by f’’,and is calle d the second derivative of f.Similarly,the nth derivative of f denoted by f^(n),is defined to be the first derivative of f^(n-1).We make the convention that f^(0) =f,that is,the zeroth derivative is the function itself.Vocabularydifferential calculus微积分differentiable可微的intergral calculus

Depending on whether you decide to reinvest(monthly,quarterly,yearly),you will receive only the initial investment,or that plus the interest you have earned after n=1,2,3,…periods of time(see Figure 18)B n=B n-1+rB0=B0(1+m)B n=B n-1(1+r)=B0(1+r)nThe relationship ΔB n /B n-1 =( B n- B n-1 ) /B n-1 =r characterizes the yield of your investment.Usually,the rate of interest,or the “yield”on the investment,r 100%,is stated for a year.we can divide this time period into m smaller periods and calculate the yield (monthly ,quarterly ,semiannually,etc.)at the end of each period,according to the stated annual rate.More frequent compounding leads to an increase in the investro’s capital;the amount B n(m)is given byB n(m)=B0(1+r/m)mn (2)If we subdivide the year into more and more periods,so that m approaches infinity ,then Bn(m)approaches B0en.In other words,the “limiting”amount of money in the bank account islim B n(m)=B0e n(3)Thhis implies that the relative yield of sunch an investment is constant and equals the interest rate r.The three methods of calculating interest discussed above are called simple ,compound ,and continuous .Formulas (1),(2)and (3)provide ways to calculate the amount in the investor’s bank account and clearly show the dependence of the value of money on time.On the other hand,we have the bank’s interest rate R,s that if we invest the amount (1-R)B1,at time 1 ,say after one year,we will receive the amount B1.This is equivalent to the issuance of a bond with a nominal value B1(to be paid to the bond holder at the end of this year),but now the bond sells for a lower price(decreased by the amount of the lending rate R over one period ,that is m=1).So today’s price is determined by the formula(1-R)B1,which is equal to the discounted price B1/(1+r) .Therefore,we can view the bank account as a coupon-free bond in the sense of a risk-free asset of the financial market.The lack of ,or very small,changes in interest rates characterize the stability of financial and economic systems ,for which the corresponding bank acccount serves as the basic non-risky asset.Reality shows that such suggestions present limits in The idealization of mathematical models for financial markets.译文：依赖于你是否决定再投资（平稳的，按季度的，一年一次的），你将仅仅收到最初的投资，否则就会加上n=1,2,3…个时期后你所赚的利息。

Differential CalculusNewton and Leibniz,quite independently of one another,were largely responsible for developing the ideas of integral calculus to the point where hitherto insurmountable problems could be solved by more or less routine methods.The successful accomplishments of these men were primarily due to the fact that they were able to fuse together the integral calculus with the second main branch of calculus,differential calculus.In this article, we give su ﬃcient conditions for controllability of some partial neutral functional di ﬀerential equations with inﬁnite delay. We suppose that the linear part is not necessarily densely deﬁned but satisﬁes the resolvent estimates of the Hille -Yosida theorem. The results are obtained using the integrated semigroups theory. An application is given to illustrate our abstract result. Key words Controllability; integrated semigroup; integral solution; inﬁnity delay1 IntroductionIn this article, we establish a result about controllability to the following class of partial neutral functional di ﬀerential equations with inﬁnite delay:0,),()(0≥⎪⎩⎪⎨⎧∈=++=∂∂t x xt t F t Cu ADxt Dxt tβφ (1) where the state variable (.)x takes values in a Banach space ).,(E and the control (.)u is given in []0),,,0(2>T U T L ,the Banach space of admissible control functions with U a Banach space.

Many authors extended the controllability concept to inﬁnite dimensional systems in Banach space with unbounded operators. Up to now, there are a lot of works on this topic, see, for example, [4, 7, 10, 21]. There are many systems that can be written as abstract neutral evolution equations with inﬁnite delay to study [23]. In recent years, the theory of neutral functional di ﬀerential equations with inﬁnite delay in inﬁnitedimension was deve loped and it is still a ﬁeld of research (see, for instance, [2, 9, 14, 15] and the references therein). Meanwhile, the controllability problem of such systems was also discussed by many mathematicians, see, for example, [5, 8]. The objective of this article is to discuss the controllability for Eq. (1), where the linear part is supposed to be non-densely deﬁned but satisﬁes the resolvent estimates of the Hille-Yosida theorem. We shall assume conditions that assure global existence and give the su ﬃcient conditions for controllability of some partial neutral functional di ﬀerential equations with inﬁnite delay. The results are obtained using the integrated semigroups theory and Banach ﬁxed point theorem. Besides, we make use of the notion of integral solution and we do not use the analytic semigroups theory.Treating equations with inﬁnite delay such as Eq. (1), we need to introduce the phase space B. To avoid repetitions and understand the interesting properties of the phase space, suppose that ).,(B B is a (semi)normed abstract linear space of functions mapping (−∞, 0] into E, and satisﬁes the following fundamental axioms that were ﬁrst introduced in [13] and widely discussedin [16].(A)There exist a positive constant H and functions K(.), M(.):++ℜ→ℜ,with K continuous and M locally bounded, such that, for any ℜ∈σand 0>a ,if x : (−∞, σ + a] → E, B x ∈σ and (.)x is continuous on [σ, σ+a], then, for every t in [σ, σ+a], the following conditions hold:(i) B xt ∈, (ii) Bt x H t x ≤)(,which is equivalent toB H ϕϕ≤)0(or every B ∈ϕ(iii) Bσσσσx t M s x t K xtts B)()(sup )(-+-≤≤≤(A) For the function (.)x in (A), t → xt is a B -valued continuous function for t in [σ, σ + a].

We consider the following deﬁnition.We say that a function x := x(., ϕ) : (−∞, T ) → E, 0 < T ≤ +∞, is an integral solution of Eq.

(4)Using Theorem 7 in [1], we obtain the following result.Theorem 1 Assume that (H1), (H2), and (H3) hold. Let ϕ ∈ B such that D ϕ ∈ D(A). Then, there exists a unique integral solution x(., ϕ) of Eq. (1), deﬁned on (−∞,+∞) .Deﬁnition 2 Under the above conditions, Eq. (1) is said to be controllable on the interval J = [0, δ], δ > 0, if for every initial function ϕ ∈ B with D ϕ ∈ D(A) and for any e1 ∈ D(A), there exists a control u ∈ L2(J,U), such that the solution x(.) of Eq.

Its history began in the 17th century when Newton, Leibniz, and the Bernoullis solved some simple differential equation arising from problems in geometry and mechanics. There early discoveries, beginning about 1690, gradually led to the development of a lot of “special tricks” for solving certain special kinds of differential equations. Although these special tricks are applicable in mechanics and geometry, so their study is of practical importance.微分方程牛顿和莱布尼茨，完全相互独立，主要负责开发积分学思想的地步，迄今无法解决的问题可以解决更多或更少的常规方法。

点没有长度，宽度和厚度，但是标记了一个位置。我们熟悉铅笔尖，针尖这样的表达。我们可以用一个小圆点来表示一个点，在它旁边用打印体大写字母来命名，如图2-2-1中的点A。
The line is named by labeling two points on it with capital letters or one small letter near it. The straight line extends infinitely far in two directions and has no ends. The part of the line between two points on the line is termed a line segment.
我们都熟悉直线，但是很难定义直线。可能可以用移动一支铅笔或者钢笔横穿一张纸留下的痕迹来描述直线。
直线可以被看做是一维的，即只有长度。尽管我们画一条直线的时候会赋予它宽度和厚度，但是当考虑直线的时候，只考虑痕迹的长度。
A point has no length, no width, and no thickness, but marks a position. We are familiar with such expressions as pencil point and needle point. We represent a point by a small dot and name it by a capital letter printed beside it, as “point A” in Fig. 2-2-1.
有三种线：直线，折线和曲线。曲线是指其中没有任何部分是直的。折线是由连起来的直线段构成，如图2-2-3中的ABCDE.

7A在日常使用的英文单词"序列"和' '系列"是同义词，和他们用来建议一系列的事情或按某种顺序排列的事件。

在数学中，这句话有特别技术的意义。

"序列"一词被受雇如在共同使用这一术语，传达的理念的一套东西排列顺序，但"系列"一词用于稍有不同的意义。

概念在本节中，将讨论序列和系列将定义第11 节。

如果为每个正整数n 有关联的真实或复数a，那时有序的集据说是定义一个无限的序列。

这里最重要的是每个成员集的已标记的整数，使我们可以发言的第一届、第二个任期，以及，一般的第n 个词。

每个学期了继任者，因此，没有任何"最后"一词。

如果我们给一些规则或第n 个词描述的公式，可以构造序列的最常见的例子。

因此，例如，公式= 1 定义的序列的第五个任期是1.有时两个或多个公式可受雇作为，例如，a=1.the 第一次在这种情况下被1 的一些术语。

另一种常见方法定义一系列是一套的说明解释了如何在一个给定的开始后进行的。

因此，我们可能= 1。

此特定的规则被称为递归公式，它定义了著名的序列，其条款被称为斐波那契数。

第一次的几个术语are1。

最重要的事情是序列的序列的这样f(n) 的每个n=1.In 事实的第n 个燕鸥是序列的序列的正整数上定义一些函数 f 的任何序列，这可能是序列的序列的最方便的方法，国家技术定义。

定义。

其域是所有积极integers1 的一组函数f 称为一个无限的序列。

函数值f(n) 调用序列的第n 个词。

通过按顺序，因此编写条款通常显示的功能（即，函数值的集合）的范围：f (2)。

为简便起见，{f(n)} 符号用于指示第n 个任期是f(n) 的序列。

由使用下标，很多时候表示，n 的依赖和我们写，或类似的而不是f (n0。

除非另外指定，否则所有的序列，在这一章中假定有真实的或复杂的条款。

7B我们担心在这里主要的问题在于决定是否条款f(n) 倾向于有限的n 无限增加。

1－A What is mathematics
Mathematics comes from man’s social practice, for example, industrial and agricultural production, commercial activities, military operations and scientific and technological researches. And in turn, mathematics serves the practice and plays a great role in all fields. No modern scientific and technological branches could be regularly developed without the application of mathematics. 数学来源于人类的社会实践，比如工农业生产，商业活动，军事行动和科学技术研究。反过来，数学服务于实践，并在各个领域中起着非常重要的作用。没有应用数学，任何一个现在的科技的分支都不能正常发展。From the early need of man came the concepts of numbers and forms. Then, geometry developed out of problems of measuring land , and trigonometry came from problems of surveying . To deal with some more complex practical problems, man established and then solved equation with unknown numbers ,thus algebra occurred. Before 17th century, man confined himself to the elementary mathematics, i.e. , geometry, trigonometry and algebra, in which only the constants are considered. 很早的时候，人类的需要产生了数和形式的概念，接着，测量土地的需要形成了几何，出于测量的需要产生了三角几何，为了处理更复杂的实际问题，人类建立和解决了带未知参数的方程，从而产生了代数学，17世纪前，人类局限于只考虑常数的初等数学，即几何，三角几何和代数。The rapid development of industry in 17th century promoted the progress of economics and technology and required dealing with variable quantities. The leap from constants to variable quantities brought about two new branches of mathematics----analytic geometry and calculus, which belong to the higher mathematics. Now there are many branches in higher mathematics, among which are mathematical analysis, higher algebra, differential equations, function theory and so on. 17世纪工业的快速发展推动了经济技术的进步，从而遇到需要处理变量的问题，从常数带变量的跳跃产生了两个新的数学分支-----解析几何和微积分，他们都属于高等数学，现在高等数学里面有很多分支，其中有数学分析，高等代数，微分方程，函数论等。Mathematicians study conceptions and propositions, Axioms, postulates, definitions and theorems are all propositions. Notations are a special and powerful tool of mathematics and are used to express conceptions and propositions very often. Formulas ,figures and charts are full of different symbols. Some of the best known symbols of mathematics are the Arabic numerals 1,2,3,4,5,6,7,8,9,0 and the signs of addition, subtraction , multiplication, division and equality. 数学家研究的是概念和命题，公理，公设，定义和定理都是命题。符号是数学中一个特殊而有用的工具，常用于表达概念和命题。公式，图表都是不同的符号……..The conclusions in mathematics are obtained mainly by logical deductions and computation. For a long period of the history of mathematics, the centric place of mathematics methods was occupied by the logical deductions. Now , since electronic computers are developed promptly and used widely, the role of computation becomes more and more important. In our times, computation is not only used to deal with a lot of information and data, but also to carry out some work that merely could be done earlier by logical deductions, for example, the proof of most of geometrical theorems. 数学结论主要由逻辑推理和计算得到，在数学发展历史的很长时间内，逻辑推理一直占据着数学方法的中心地位，现在，由于电子计算机的迅速发展和广泛使用，计算机的地位越来越重要，现在计算机不仅用于处理大量的信息和数据，还可以完成一些之前只能由逻辑推理来做的工作，例如，大多数几何定理的证明。 Biblioteka 1－B Equation

1-A：什么是数学数学来源于人类的社会实践，包括工农业的劳动，商业、军事和科学技术研究等活动。

反过来，数学服务于实践并在所有领域扮演一个重要的角色。

没有数学的应用，现代化科学和技术的分支都不能有规律的发展。

从早期人类的需求引出了数和形状。

然后，几何学因测量陆续的发展出来，三角学来自于勘探问题。

为了处理一些更复杂的实践问题，人们建立了方程，通过求解方程的未知数，从而代数学出现了。

17世纪之前，人们局限于初等数学，例如几何、三角和代数，那些只考虑常数。

17世纪工业的迅速发展促进了经济学和科技的发展，并且我们需要处理变量。

从常数到变量的跳跃带来了两个属于高等数学的新的数学分支，解析几何和微积分学。

现在，高等数学中有了许多分支，数学分析、高等代数、微分方程、函数论等。

数学家们研究概念和命题。

公理、公社、定义和定理都是命题。

符号是一种特别并且很重要的数学工具，它常用于表示概念和命题。

公式、图形和表格充满着不同的符号。

阿拉伯数字1,2,3,4,5,6,7,8,9,0和加”+”减”-”乘”*”除”/”等号”=”使我们最熟悉的数学符号。

主要通过逻辑推导和计算来获得数学结论。

在数学史的很长的时期内，逻辑推论一直占据数学方法的中心地位。

现在，自从电子计算机迅速发展和广泛应用，计算的角色越来越重要。

现在，计算不仅用来处理信息与数据，而且用来完成一些在以前只能靠逻辑推理来做的工作，例如证明大多数的几何定理。

1-B：等式等式是关于两个数或数的符号相等的一种陈述。

因此a(a-5)=a^2-5a和x-3=5是等式。

等式有两种，恒等式和条件等式。

算术和代数恒等式是等式。

这种等式的两端要么一样，要么经过执行指定的运算后变成一样。

因此12-2=2+8，(m-n)(m+n)=m^2-n^2是恒等式。

含有字母的恒等式对其中字母的任何一组数值都成立。

因此恒等式x(a+2)=ax+2x变成3(7+2)=21+6或27=27，比如当x=3和a=7。

学专业英语－How to Write Mathematics?How to Write Mathematics?------ Honesty is the Best PolicyThe purpose of using good mathematical language is, of course, to make the u nderstanding of the subject easy for the reader, and perhaps even pleasant. The style should be good not in the sense of flashy brilliance, but good in the se nse of perfect unobtrusiveness. The purpose is to smooth the reader’s wanted, not pedantry; understanding, not fuss.The emphasis in the preceding paragraph, while perhaps necessary, might see m to point in an undesirable direction, and I hasten to correct a possible misin terpretation. While avoiding pedantry and fuss, I do not want to avoid rigor an d precision; I believe that these aims are reconcilable. I do not mean to advise a young author to be very so slightly but very very cleverly dishonest and to gloss over difficulties. Sometimes, for instance, there may be no better way t o get a result than a cumbersome computation. In that case it is the author’s duty to carry it out, in public; the he can do to alleviate it is to extend his s ympathy to the reader by some phrase such as “unfortunately the only known proof is the following cumbersome computation.”Here is the sort of the thing I mean by less than complete honesty. At a certa in point, having proudly proved a proposition P, you feel moved to say: “Not e, however, that p does not imply q”, and then, thinking that you’ve done a good expository job, go happily on to other things. Your motives may be per fectly pure, but the reader may feel cheated just the same. If he knew all abo ut the subject, he wouldn’t be reading you; for him the nonimplication is, qui te likely, unsupported. Is it obvious? (Say so.) Will a counterexample be suppl ied later? (Promise it now.) Is it a standard present purposes irrelevant part of the literature? (Give a reference.) Or, horrible dictum, do you merely mean th at you have tried to derive q from p, you failed, and you don’t in fact know whether p implies q? (Confess immediately.) any event: take the reader into y our confidence.There is nothing wrong with often derided “obvious”and “easy to see”, b ut there are certain minimal rules to their use. Surely when you wrote that so mething was obvious, you thought it was. When, a month, or two months, or six months later, you picked up the manuscript and re-read it, did you still thi nk that something was obvious? (A few months’ripening always improves ma nuscripts.) When you explained it to a friend, or to a seminar, was the someth ing at issue accepted as obvious? (Or did someone question it and subside, mu ttering, when you reassured him? Did your assurance demonstration or intimidation?) the obvious answers to these rhetorical questions are among the rules th at should control the use of “obvious”. There is the most frequent source o f mathematical error: make that the “obvious”is true.It should go without saying that you are not setting out to hide facts from the reader: you are writing to uncover them. What I am saying now is that you should not hide the status of your statements and your attitude toward them eit her. Whenever you tell him something, tell him where it stands: this has been proved, that hasn’t, this will be proved, that won’t. Emphasize the importan t and minimize the trivial. The reason saying that they are obvious is to put t hem in proper perspecti e for the uninitiated. Even if your saying so makes an occasional reader angry at you, a good purpose is served by your telling him how you view the matter. But, of course, you must obey the rules. Don’t le t the reader down; he wants to believe in you. Pretentiousness, bluff, and conc ealment may not get caught out immediately, but most readers will soon sense that there is something wrong, and they will blame neither the facts nor them selves, but quite properly, the author. Complete honesty makes for greatest clar ity.---------Paul R.Haqlmosvocabularyflashy 一闪的 counter-example 反例unobtrusiveness 谦虚dictum 断言；格言forestall 阻止，先下手deride嘲弄anticipate 预见 subside沉静pedantry 迂腐；卖弄学问 mutter出怨言，喃喃自语fuss 小题大做 intimidation威下reconcilable 使一致的 rhetorical合符修辞学的gloss 掩饰 pretentiousness自命不凡alleviate 减轻，缓和bluff 欺骗implication 包含，含意concealment隐匿notes1. 本课文选自美国数学学会出版的小册子How to write mathematics 中Paul R.Halmos. 的文章第9节2.
