11. lecture - Define and measure
数学专业英语 第2章课后答案
2.12.比:ratio 比例:proportion 利率:interest rate 速率:speed 除:divide 除法:division 商:quotient 同类量:like quantity 项:term 线段:line segment 角:angle 长度:length 宽:width高度:height 维数:dimension 单位:unit 分数:fraction 百分数:percentage3.(1)一条线段和一个角的比没有意义,他们不是相同类型的量.(2)比较式通过说明一个量是另一个量的多少倍做出的,并且这两个量必须依据相同的单位.(5)为了解一个方程,我们必须移项,直到未知项独自处在方程的一边,这样就可以使它等于另一边的某量.4.(1)Measuring the length of a desk, is actually comparing the length of the desk to that of a ruler.(3)Ratio is different from the measurement, it has no units. The ratio of the length and the width of the same book does not vary when the measurement unit changes.(5)60 percent of students in a school are female students, which mean that 60 students out of every 100 students are female students.2.22.初等几何:elementary geometry 三角学:trigonometry 余弦定理:Law of cosines 勾股定理/毕达哥拉斯定理:Gou-Gu theorem/Pythagoras theorem 角:angle 锐角:acute angle 直角:right angle 同终边的角:conterminal angles 仰角:angle of elevation 俯角:angle of depression 全等:congruence 夹角:included angle 三角形:triangle 三角函数:trigonometric function直角边:leg 斜边:hypotenuse 对边:opposite side 临边:adjacent side 始边:initial side 解三角形:solve a triangle 互相依赖:mutually dependent 表示成:be denoted as 定义为:be defined as3.(1)Trigonometric function of the acute angle shows the mutually dependent relations between each sides and acute angle of the right triangle.(3)If two sides and the included angle of an oblique triangle areknown, then the unknown sides and angles can be found by using the law of cosines.(5)Knowing the length of two sides and the measure of the included angle can determine the shape and size of the triangle. In other words, the two triangles made by these data are congruent.4.(1)如果一个角的顶点在一个笛卡尔坐标系的原点并且它的始边沿着x轴正方向，这个角被称为处于标准位置.(3)仰角和俯角是以一条以水平线为参考位置来测量的,如果正被观测的物体在观测者的上方,那么由水平线和视线所形成的角叫做仰角.如果正被观测的物体在观测者的下方,那么由水平线和视线所形成的的角叫做俯角.(5)如果我们知道一个三角形的两条边的长度和对着其中一条边的角度,我们如何解这个三角形呢?这个问题有一点困难来回答,因为所给的信息可能确定两个三角形,一个三角形或者一个也确定不了.2.32.素数:prime 合数:composite 质因数:prime factor/prime divisor 公倍数:common multiple 正素因子: positive prime divisor 除法算式:division equation 最大公因数:greatest common divisor(G.C.D) 最小公倍数: lowest common multiple(L.C.M) 整除:divide by 整除性:divisibility 过程:process 证明:proof 分类:classification 剩余:remainder辗转相除法:Euclidean algorithm 有限集:finite set 无限的:infinitely 可数的countable 终止:terminate 与矛盾:contrary to3.(1)We need to study by which integers an integer is divisible, that is , what factor it has. Specially, it is sometime required that an integer is expressed as the product of its prime factors.(3)The number 1 is neither a prime nor a composite number;A composite number in addition to being divisible by 1 and itself, can also be divisible by some prime number.(5)The number of the primes bounded above by any given finite integer N can be found by using the method of the sieve Eratosthenes.4.(1)数论中一个重要的问题是哥德巴赫猜想,它是关于偶数作为两个奇素数和的表示.(3)一个数,形如2p-1的素数被称为梅森素数.求出5个这样的数.(5)任意给定的整数m和素数p,p的仅有的正因子是p和1,因此仅有的可能的p和m的正公因子是p和1.因此,我们有结论:如果p是一个素数,m是任意整数,那么p整除m,要么(p,m)=1.2.42.集:set 子集:subset 真子集:proper subset 全集:universe 补集:complement 抽象集:abstract set 并集:union 交集:intersection 元素:element/member 组成:comprise/constitute包含:contain 术语:terminology 概念:concept 上有界:bounded above 上界:upper bound 最小的上界:least upper bound 完备性公理:completeness axiom3.(1)Set theory has become one of the common theoretical foundation and the important tools in many branches of mathematics.(3)Set S itself is the improper subset of S; if set T is a subset of S but not S, then T is called a proper subset of S.(5)The subset T of set S can often be denoted by {x}, that is, T consists of those elements x for which P(x) holds.(7)This example makes the following question become clear, that is, why may two straight lines in the space neither intersect nor parallel.4.(1)设N是所有自然数的集合,如果S是所有偶数的集合,那么它在N中的补集是所有奇数的集合.(3)一个非空集合S称为由上界的,如果存在一个数c具有属性:x<=c对于所有S中的x.这样一个数字c被称为S的上界.(5)从任意两个对象x和y，我们可以形成序列（x，y），它被称为一个有序对，除非x=y，否则它当然不同于（y，x）.如果S和T是任意集合，我们用S*T表示所有有序对（x,y),其中x术语S，y属于T.在R.笛卡尔展示了如何通过实轴和它自己的笛卡尔积来描述平面的点之后，集合S*T被称为S和T的笛卡尔积.2.52.竖直线:vertical line 水平线:horizontal line 数对:pairs of numbers 有序对:ordered pairs 纵坐标:ordinate 横坐标:abscissas 一一对应:one-to-one 对应点:corresponding points圆锥曲线:conic sections 非空图形:non vacuous graph 直立圆锥:right circular cone 定值角:constant angle 母线:generating line 双曲线:hyperbola 抛物线:parabola 椭圆:ellipse退化的:degenerate 非退化的:nondegenerate任意的:arbitrarily 相容的:consistent 在几何上:geometrically 二次方程:quadratic equation 判别式:discriminant 行列式:determinant3.(1)In the planar rectangular coordinate system, one can set up aone-to-one correspondence between points and ordered pairs of numbers and also a one-to-one correspondence between conic sections and quadratic equation.(3)The symbol can be used to denote the set of ordered pairs（x，y）such that the ordinate is equal to the cube of the abscissa.（5）According to the values of the discriminate，the non-degenerate graph of Equation （iii） maybe known to be a parabola， a hyperbolaor an ellipse.4.（1）在例1，我们既用了图形，也用了代数的代入法解一个方程组（其中一个方程式二次的，另一个是线性的）。

(OK if the comp’s D not too high (+ can assume their D/V is stable))
3. Use the comps’ βA to estimate the project’s βA (e.g., as average). 4. Use estimated βA to calculate the all-equity cost of capital kA
How we get there:
Get D/V from comps, business plan, checklist, etc.

Cost of debt capital: kD
What we want: Expected return for creditors if project were a stand-alone with leverage ratio D/(D+E) estimated above. Imperfect approach to what we want: kD close the interest rate charged to project as stand-alone (unless debt is very risky). How we get there:
is reported as cash outflow but is not one Add (1-t)*Dep however, depreciation does imply a cash inflow of t*Dep. Altogether + Dep

2.Purchasing Power Parity (PPP)
•
Purchasing Power Parity states that an exchange rate between two countries should equal the ratio of the price level in one country to the price level in the other country.
%△XR
%△Pus %△Puk
For example: suppose inflation rate is 10% in the U.S. ,5% in the U.K. The R($/￡) increases 5% in the long-run.
3.Purchasing Power Parity In The Short Run And The Long Run
Big Mac index ,Jan 22nd 2009
• Helpfully, a UBS report published this week offers a handy guide to how long it takes a worker on the average net wage to earn the price of a Big Mac in 73 cities. Fast-food junkies are best off in Chicago, Toronto and Tokyo, where it takes a mere 12 minutes at work to afford a Big Mac. By contrast, employees must toil for over two hours to earn enough for a burger fix in Mexico City, Jakarta and Nairobi.

研究生英语-多维教程熟谙(正文翻译+课后练习参考答案)
Unit1 从能力到责任当代的大学生对他们在社会中所扮演的角色的认识模糊不清。
他们致力于寻求在他们看来似乎是最现实的东西：追求安全保障，追逐物质财富的积累。
年轻人努力想使自己成人成才、有所作为，但他们对未来的认识还是很模糊的。
处于像他们这样前程未定的年龄阶段，他们该信仰什么?大学生一直在寻找真我的所在，寻找生活的意义。
一如芸芸众生的我们，他们也陷入了两难的境地。
一方面，他们崇尚奉献于人的理想主义，而另一方面，他们又经不住自身利益的诱惑，陷入利己主义的世界里欲罢不能。
最终而言，大学教育素质的衡量取决于毕业生是否愿意为他们所处的社会和赖以生存的城市作出贡献。
尼布尔曾经写道：“一个人只有意识到对社会所负有的责任，他才能够认识到自身的潜力。
一个人如果一味地以自我为中心，他将会失去自我。
”本科教育必须对这种带有理想主义色彩的观念进行自我深省，使学生超越以自我为中心的观念，以诚相待，服务社会。
在这一个竞争激烈＼残酷的社会，人们期望大学生能报以正直、文明，，甚至富有同情心的人格品质去与人竞争，这是否已是一种奢望?人们期望大学的人文教育会有助于培养学生的人际交往能力，如今是否仍然适合?毫无疑问，大学生应该履行公民的义务。
美国的教育必须立刻采取行动，使教育理所当然地承担起弥合公共政策与公众的理解程度之间的极具危险性且在日益加深的沟壑这一职责。
那些要求人们积极思考政府的议程并提供富于创意的意见的信息似乎越来越让我们感到事不关己。
所以很多人认为想通过公众的参与来解决复杂的公共问题已不再可能行得通。
设想，怎么可能让一些非专业人士去讨论必然带来相应后果的政府决策的问题，而他们甚至连语言的使用都存在困难?核能的使用应该扩大还是削弱?水资源能保证充足的供应吗?怎样控制军备竞赛?大气污染的安全标准是多少?甚至连人类的起源与灭绝这样近乎玄乎的问题也会被列入政治议事日程。
类似的一头雾水的感觉，公众曾经尝试过。
当他们试图弄懂有关“星球大战”的辩论的问题时，那些关于“威慑”与“反威慑”等高科技的专业术语，曾让公众一筹莫展。

Naturally, the more property a person owns, the more he has to lose. Similarly, the more family responsibility a person has, the greater the impact if he of she dies or becomes physically disabled. Having insurance can reduce one’s concern about the possibility of suffering a loss of property or a disabling accident. Yet, is it wise to spend money on insurance even though a claim may never be made? Is keeping a spare tire in the car a wasted investment, even if the tire is never needed? The sense of security to the car driver may make the expense of the extra tire worthwhile. While financial compensation cannot make up for certain losses, it may compensate for other losses.

量子物理课堂习题
量子物理课堂习题Lecture 1: 旧量子论1.求氘原子Hα线n=2到n=3的波数2.Ce的逸出功是1.9eV, 求阈值频率和波长3.对于氢原子、一次电离的氦离子He+和两次电离的锂粒子Li++,分别计算它们的：a)第一、第二波尔轨道半径及电子在这些轨道上的速度b)电子在基态的结合能c)第一激发态退激到基态所放光子的波长Lecture 2：波粒二象性不确定性原理=a（n＝1，2，…, a 为弦长）。
按照“定态即驻波”的说1.已知琴弦振动的驻波条件为nλ2法，束缚在长宽高分别为a，b，c 的三维势箱中的粒子(质量为m)的定态能量取值是多少？2.一原子的激发态发射波长为600nm 的光谱线，测得波长的精度为∆λ/λ=10−7,试问该原子态的寿命为多长？3.1，3—丁二烯分子长度a≈7Å，试用测不准关系估计其基电子态能级的大小（量级）Lecture 3: 波函数薛定谔方程1.下列哪些函数不是品优函数，说明理由：f(x)=x2,e−|x|,sin(x),e−x22.试写出下列体系的定态薛定谔方程：（a）He 原子（b）H2 分子3.写出一个被束缚在半径为a的圆周上运动的粒子的Schrödinger 方程，并求其解Lecture 4: 势箱模型1.（2.7）Consider a particle with quantum number n moving in a one-dimensional box of lengthl.(a) Determine the probability of finding the particle in the left quarter of the box.(b)For what value of n is this probability a maximum?(c) What is the limit of this probability for n→∞?(d) What principle is illustrated in (c)?2.（2.17）A crude treatment of the pi electrons of a conjugated molecule regards theseelectrons as moving in the particle-in-a-box potential of Fig. 2.1, where the box length issomewhat more than the length of the conjugated chain. The Pauli exclusion principle(Chapter 10) allows no more than two electrons to occupy each box level. (These two haveopposite spins.) For 1,3-butadiene, CH2 =CHCH=CH2, take the box length as 7.0 Å and usethis model to estimate the wavelength of light absorbed when a p electron is excited from thehighest-occupied to the lowest-vacant box level of the molecular electronic ground state. The experimental value is 217 nm.3.(2.18) For the particle in a one-dimensional box of length 1, we could have put the coordinateorigin at the center of the box. Find the wave functions and energy levels for this choice of origin.4.试用一维势箱模型(6个电子)计算如下分子的电子光谱最大吸收波长（第一吸收峰）。

The Kano model
Delighter
To test if a characteristic is basic, performance or delighter ask two questions 1. 2. How do you feel if the characteristic is absent ? How do you feel if the characteristic is present ?
The SIPOC is a useful framework to maintain the big picture perspective
Define – Voice of the customer (VOC)
Vital for every company
Solid starting point for making a VOC plan is to use the “Six serving men”.
Introduction to Define and measure
DMAIC and PDCA cycle
The DMAIC Wheel The PDCA cycle
DMAIC - Define
Define - Project charter
Define – The SIPOC diagram
Define – Voice of tion
• Proactive data – observation, interviews etc. • Reactive data – customer feedback, warranty claims etc.
“Once you embrace unpleasant news not as a negative but as evidence of a need of change, you aren’t defeated by it. You’re learning from it” (Bill Gates)
If 1 = bad, 2 = neutral, it is a basic If 1 = neutral, 2 = good, it is a delighter If the answer is “it depends”, it is a performance
Define – Voice of the customer (VOC)
“I knew six honest serving men, they taught me all I knew; their names are what and why and when, and where and how and who” Who What Why Where When How are the customers? do they want? do they want it? do they want it? do they want it? do they want it?

Exercise
Honda is preparing a Hybrid car. Read the article as a foundation for your understanding. Use Six serving men, the Kano model and CTQ tree to make your own analyse of Honda’s project. When doing the CTQ tree the need for Honda is to produce a hybrid car that customers want to buy – you must come up with drivers and ctq characteristics. If the article does not give you sufficient information then use your common sense. Do the exercise in groups of 2.
