小径分岔的花园集 理解

小径分岔的花园集理解英文回答:The garden of the forked paths is a short story written by Argentine writer Jorge Luis Borges. It was first published in 1941 and is considered one of Borges' most famous and influential works. The story revolves around a Chinese spy named Ts'ui Pên wh o creates a labyrinthine garden with multiple paths that branch off in different directions.The garden is described as a complex and intricate place, with paths that twist and turn, leading to various destinations. Each path represents a different possible outcome or future, creating a sense of uncertainty and ambiguity. The concept of the garden serves as a metaphor for the choices and decisions we make in life, and the idea that every choice we make leads us down a different path.The protagonist of the story, Yu Tsun, is a descendantof Ts'ui Pên and is tasked with delivering a secret message to his German handlers during World War I. As he navigates the garden, he realizes that the paths are not just physical but also symbolic, representing the different possibilities and outcomes of his mission. He comes to understand that the garden is a manifestation of Ts'uiPên's philosophy, which emphasizes the interconnectedness of all things and the idea that time is not linear but rather a network of possibilities.Ultimately, the story explores themes of determinism, free will, and the nature of time. It raises questions about the choices we make and the paths we take in life, and whether or not we have control over our own destinies. It challenges traditional notions of cause and effect, suggesting that multiple outcomes can exist simultaneously and that our actions can have far-reaching consequences.In conclusion, the garden of the forked paths is a rich and thought-provoking story that delves into philosophical and metaphysical concepts. It invites readers to contemplate the nature of choice, time, and theinterconnectedness of all things.中文回答:《分岔的花园》是阿根廷作家豪尔赫·路易斯·博尔赫斯创作的一篇短篇小说。

Ramsey模型的基本思想:国民收入()Y F K AL=。

所以经济增长决定于资本存量K、人,口L和劳动有效性A的增长。

在Solow和Ramsey增长模型中,人口L和劳动有效性A的增长率外生给定。

因此,必须研究经济增长与资本存量增长之间的关系。

资本存量的变化源于投资,投资形成于储蓄,所以,储蓄率影响资本存量的变化并进而影响经济增长。

在Solow模型中,储蓄率为外生变量。

但是在Ramsey模型中为内生变量,我们必须分析决定储蓄率的机制。

国民产出(收入)分为消费和储蓄两部分。

所以,分析储蓄必须分析消费。

家庭的消费行为是在生命周期收入约束下使其效用最大。

Happiness is far more than a strong body, a magnificent villa or an around-the-world tour; it is something we need from our heart. However, we can investigate happiness through scientific methods.AWhen we are asked the question Where can we find happiness , it is a puzzle difficult to answer accurately. We can find happiness right in our own home, in our workplace, in school, in the company of our friends, etc. It is up to us to find the ways and means to achieve that happiness each of us seek and long for. However, it is essential to recognize that there is no one absolute way to achieve happiness. People may have different ideaswith regard to the ways of achieving happiness. The following five classifications are perceived by many people as sources of happiness: family and friends, wealth, position, educational achievement and fame.BTo give it a comprehensive definition, happiness is a mental state of well-being characterized by positive or pleasant emotions ranging from contentment to intense joy. A variety of biological, psychological, religious, and philosophical approaches have striven to define happiness and identify its sources. Various research groups, including Positive Psychology, endeavor to apply the scientific method to answer questions about what happiness is, and how we might attain it. While philosophers and religious thinkers often define happiness in terms of living a good life, or flourishing, rather than simply as an emotion. Happiness in this sense was used to translate the Greek Eudaimonia, and is still used in virtue ethics.CWhile the level of physical healthiness is the biggest determinant of happiness, comparison of financial success with others of the same age group is the second largest source of happiness and unhappiness. Financially richer people tend to be happier than poorer people, according to sociological researcher Glenn Firebaugh of Pennsylvania State University. Their research is focused on whether the income effect on happiness results largely from the things money can buy (absolute income effect) or from comparing one s income to the income of others (relative income effect). They present their research in a session paper, tided Relative Income and Happiness: Arc Americans on a Hedonk Treadmill? Firebaugh argues that, in evaluating their own incomes, individuals compare themselves to their peers of the same age. Therefore, a persons reported level of happiness dependson how his or her income compares to others in the same age group. Using comparison groups on the basis of age, the researchers find evidence of both relative and absolute effects, but relative income is more important than absolute income in determining the happiness of individuals in the United States. This may result in a self-indulgent treadmill, because incomes in the United States rise over most of the adult lifespan. They always dissatisfy with the salary. For e_ample, the survey indicates that the students studied in Harvard University e_pect to earn much more money than their classmates rather than care about the e_act amount of the salary.DWe have long been aware that elements from various perspectives of We could contribute to realizing happiness. The Minnesota Study of Twins Reared Apart (MISTRA) has recently conducted a research project, choosing _0 pairs of reared-apart twins as subjects to test their perception of happiness. In an early report of results it was found that, on most measurable psychological traits, the level of welfare between the twins in a set felt is varied instead of being the same or similar. Thus environmental factors may not be the only factor that affects the feeling of happiness significantly. In another investigation, among persons of European ancestry, for psychological features that can be measured, heritability range from about 25 percent to 80 percent. Or, to put it more concretely, from one-fourth to four-fifths of the variation from person to person in such features as IQ, creativity and happiness, is associated with genetic differences between those persons. That indicates that genetic difference may also affect the happiness. Furthermore, neurobiological evidence shows that left and right frontal lobes play different roles in the emotion (MC) (M). Happiness is a type of emotion, a positive one. From the e_periments, happiness and the left prefrontal lobe are combinedtogether. The more active it is, the more positive emotion you sense.EAt the outset of new millennium, a global research had a result that the people living in the modern world were even unhappier. With crises being on the rise these days, finding happiness can be a bit challenging. Despite of all the stresses associated with life, we still do our best to be happy — because being happy is the only way to keep us afloat. Happiness is considered a very important therapy, both physically and mentally. With it, we are inspired to accomplish whatever goals we want to achieve. It s a strong drive that keeps us going and helps us live our life every single day.FThere are many ways to be happy. Spend time with individuals who are dear to you. There is nothing more joyful than to be with the people you love. During the weekends, try to schedule a fun trip for you and your partner, or one for your whole family. Just go somewhere else for a change and enjoy the change of scenery. Do something nice for others. Helping others is a very honorable way to find happiness. If your schedule is too tight for volunteer work, you can just donate a small sum of money or some old clothes or toys to charity. When you eat out, try to be a good tipper to the waiters or the valet who safely parked your car. All these simple things will not only make you happy, but other people as well. Start and end your day with a smile. Smiling is a very powerful gesture. There s no need for words to describe how pleasant it is. If you have a lousy day, smile your way out of the office. When people smile back at you, it will uplift your mood and make you feel better. Spending some time with your friends. A close circle of friends is one of the most important sources of happiness.Questions 1-5The reading Passage has si_ paragraphs A-FChoose the correct heading for paragraphs A-E from the list of headings below.Write the appropriate number, i-i_. in bo_es 1-5 on your answer sheet.

Summary (总结题)正向的选择:Lascaux Cave PaintingsIn Southwest France in the 1940’s, playing children discovered Lascaux Grotto, a series of narrow cave chambers that contain huge prehistoric paintings of animals. Many of these beasts are as large as 16 feet (almost 5 meters). Some follow each other in solemn parades, but others swirl about, sideways and upside down. The animals are bulls, wild horses, reindeer, bison, and mammoths outlined with charcoal and painted mostly in reds, yellow, and browns. Scientific analysis reveals that the colors were derived from ocher and other iron oxides ground into a fine powder. Methods of applying color varied: some colors were brushed or smeared on rock surfaces and others were blown or sprayed. It is possible that tubes made from animal bones were used for spraying because hollow bones, some stained with pigment, have been found nearby.One of the most puzzling aspects of the paintings is their location. Other rock paintings—for example, those of Bushmen in South Africa—are either located near cave entrances or completely in the open. Cave paintings in France and Spain, however, are in recesses and caverns far removed from original cave entrances. This means that artists were forced to work in cramped spaces and without sources of natural light. It also implies that whoever made them did not want them to be easily found. Since cave dwellers normally lived close to entrances, there must have been some reason why so many generations of Lascaux cave dwellers hid their art.Scholars offer three related but different opinions about the mysterious origin and significance of these paintings. One opinion is that the paintings were a record of seasonal migrations made by herds. Because some paintings were made directly over others, obliterating them, it is probable that a painting’s value ended with the migration it pictured. Unfortunately, this explanation fails to explain the hidden locations, unless the migrations were celebrated with secret ceremonies.Another opinion is that the paintings were directly related to hunting and were an essential part of a special preparation ceremony. This opinion holds that the pictures and whatever ceremony they accompanied were an ancient method of psychologically motivating hunters. It is conceivable that before going hunting the hunters would draw or study pictures of animals and imagine a successful hunt. Considerable support exists for this opinion because several animals in the pictures are wounded by arrows and spears. This opinion als o attempts to solve the overpainting by explaining that an animal’s picture had no further use after the hunt.A third opinion takes psychological motivation much further into the realm of tribal ceremonies and mystery: the belief that certain animals assumed mythical significance as ancient ancestors or protectors of a given tribe or clan. Two types of images substantiate this theory: the strange, indecipherable geometric shapes that appear near some animals, and the few drawings of men. Wherever men appear they are crudely drawn and their bodies are elongated and rigid. Some men are in a prone position and some have bird or animal heads.Advocates for this opinion point to reports from people who have experienced a trance state, a highly suggestive state of low consciousness between waking and sleeping. Uniformly, these people experienced weightlessness and the sensation that their bodies were being stretched lengthwise. Advocates also point to people who believe that the forces of nature are inhabited by spirits, particularly shamans* who believe that an animal’s spirit and energy is transferred to them while in a trance. One Lascaux narrative picture, which shows a man with a birdlike head and a wounded animal, would seem to lend credence to this third opinion, but there is still much that remains unexplained. For example, where is the proof that the man in the picture is a shaman? He could as easily be a hunter wearing a headmask. Many tribal hunters, including some Native Americans, camouflaged themselves by wearing animal heads and hides.Perhaps so much time has passed that there will never be satisfactory answers to the cave images, but their mystique only adds to their importance. Certainly a great art exists, and by its existence reveals that ancient human beings were not without intelligence, skill, and sensitivity.13.

金字塔的数学名词解释英文

金字塔的数学名词解释英文

金字塔的数学名词解释英文The Explanation of Mathematical Terms in English Regarding the PyramidIntroductionThe pyramid, with its majestic and iconic structure, has captured the fascination of humankind for centuries. Not only is it a symbol of ancient civilizations, but it also embodies a sophisticated understanding of mathematics. In this article, we will explore and decode various mathematical terms related to the pyramid in English.The BaseThe base of a pyramid refers to the bottom polygon upon which the whole structure rests. In mathematical terms, it is often referred to as the "base polygon." The base can take different shapes depending on the type of pyramid. For example, a square pyramid has a base in the shape of a square, while a triangular pyramid has a base in the shape of a triangle.The ApexThe apex of a pyramid is the pointy top where all the edges converge. In mathematical terms, it is sometimes referred to as the "vertex" or "tip" of the pyramid. The apex is a critical point because it determines the height of the pyramid.HeightThe height of a pyramid is the perpendicular distance from the apex to the base. In mathematical terms, it can also be called the "altitude." The height can be calculated using various methods, depending on the type of pyramid. For example, in a triangular pyramid, the height can be found by extending a perpendicular line from the apex to the base.Slant HeightThe slant height of a pyramid is the distance from any point on the base to a point on an inclined face, following the surface of the pyramid. In mathematical terms, it is also known as the "generatrix." The slant height is a crucial measurement in determining the lateral area and surface area of the pyramid.Lateral AreaThe lateral area of a pyramid represents the total surface area excluding the base. In mathematical terms, it is the sum of the areas of all the faces, excluding the base. Calculating the lateral area involves finding the area of each face and summing them up. The lateral area is an important value when studying the geometry and volume of the pyramid.Surface AreaThe surface area of a pyramid includes both the base and the lateral area. It represents the total area taken up by the pyramid's faces. In mathematical terms, it is the sum of the lateral area and the area of the base.VolumeThe volume of a pyramid refers to the amount of space enclosed by the pyramid. In mathematical terms, it is calculated by multiplying the area of the base with the height and dividing the result by 3. The volume of a pyramid is often expressed in cubic units and is used to estimate the amount of material needed to construct or fill a pyramid.SimilaritySimilarity is a mathematical concept used to describe the relationship between two objects that have the same shape but possibly different sizes. In the case of pyramids, if the corresponding angles and proportions of the faces are equal, the pyramids are considered similar. Similarity plays a crucial role in various geometric calculations and theories associated with pyramids.ConclusionThe mathematical understanding of the pyramid goes beyond its awe-inspiring structure and ancient symbolism. By exploring and decoding the various mathematical terms related to the pyramid in English, we gain a deeper appreciation for the intricate calculations and measurements involved in studying pyramids. From the base and apex to the height and volume, these terms provide the framework for understanding the mathematical complexities behind these magnificent structures.。

法国数学家拉格朗日著作《解析函数论》英文名

法国数学家拉格朗日著作《解析函数论》英文名Analytic Function Theory by French Mathematician LagrangeAnalytic Function Theory is a seminal work in the field of mathematics authored by the renowned French mathematician Joseph-Louis Lagrange. This groundbreaking book laid the foundation for the modern study of complex analysis and has been influential in shaping the development of many areas of mathematics.Published in 1797, Analytic Function Theory is considered one of the most important works in the history of mathematics. In this book, Lagrange presents a comprehensive and systematic treatment of the theory of analytic functions, which are functions that can be expanded in a power series in a complex variable.One of the key contributions of Analytic Function Theory is Lagrange's development of the concept of a complex analytic function. He introduced the idea of a function that is differentiable in the complex sense, meaning that it satisfies the Cauchy-Riemann equations. This laid the groundwork for the development of the theory of holomorphic functions, which has become a central topic in modern mathematics.Lagrange also made important contributions to the theory of series and integral calculus in Analytic Function Theory. He introduced the concept of a Laurent series, which is a generalization of the Taylor series that can be used to represent functions with poles and branch points. Lagrange's work on integration theory also laid the foundation for the development of the theory of complex integration, which has applications in areas such as physics and engineering.In addition to his mathematical contributions, Lagrange's writing style in Analytic Function Theory is noted for its clarity and precision. His rigorous approach to mathematics and his ability to present complex ideas in a clear and concise manner have made Analytic Function Theory a classic text that is still widely studied and referenced today.Overall, Analytic Function Theory is a landmark work in the history of mathematics that has had a lasting impact on the field. Lagrange's insights and discoveries in this book have shaped the way mathematicians approach the study of complex analysis, and his influence can be seen in a wide range of mathematical disciplines.。

协定塔勒简述曩l_≥l中期钱跨;值),但铸币的纯度和外观不变.法兰克大行政区在1754年9月3日接受巴伐利亚的克莱采体系,士瓦本大区于1755年7月19日接受,萨尔茨堡于同年9月20日接受,七年战争后传播到德意志其他邦国的,正是这个改变后的协定形式.这是实物塔勒(Speziestaler)的情况,即实际铸造出来的流通硬币.在当时还有一种结算塔勒(Rechnungstaler)系统,或称为记帐塔勒,和实物塔勒相对应,即不实际铸造,而只是在商业或财务上用来记帐的,有相对固定汇率的虚拟货币单位.根据硬币协定1结算塔勒等于90奥地利克莱采,或者108巴伐利亚克莱采,因此1实物塔勒=4/3结算塔勒,l0塔勒纯度:13—1/3结算塔勒纯度.而奥地利的结算古尔登遵守硬币协定,价值60奥地利克莱采,巴伐利亚引人了所谓的"莱茵古尔登"作为自己的结算古尔登单位,也价值60巴伐利亚克莱采,即1科隆马克纯银铸造20枚古尔登:1440克莱采=24莱茵古尔登,因此为区别于最初的协定币制,巴伐利亚修改后的协定币制又被称为24古尔登纯度(表2).表2巴伐利亚修改后的硬币协定主辅币汇率和最初的硬币协定汇率对比实物货币结算货币塔勒古尔登塔勒古尔登一24占尔登纯度(巴伐利亚等)144LKr.72LKLlO8LK60LKr.20古尔登纯度(奥地利等)l2OKr.60Kr.90Kr.60Kr.此处K表示24古尔登纯度克莱采,Kr.表示2O古尔登纯度克莱采. 一24古尔登纯度对应的结算古尔登为"莱茵古尔登".协定硬币的外观和铸造情况为区别于旧制塔勒,许多协定塔勒上有标志性的文字,XEINEFEINEMARK,即"十枚含一马克纯银",文字写法各邦国略有出入,比如以德文ZEHN(十)代替罗马数字x,"马克"拼写成MARCK,或者缩写成x.E.F.M.等等.l/2协定塔勒类推为XXEINEFEINEMARK(二十枚含一马克纯银).或者ADNORMAMCONVENTIONIS,即拉丁文"根据协定标准",1塔勒和1/2塔勒文字一样,各邦国间也有缩写等变异.此两种文字也有同时出现在一枚硬币上的,也有做成边铭的,形式多种多样.由于硬币协定中并没有统一硬币铭文的规定,所以并非所有的协定塔勒上都有XEINEFEINEMARK或者ADNORMAMCONV.ENTIONIS字样.包括作为其发端的巴伐利亚,初期铸造的大量协定塔勒,币面上也没有区别予旧制塔勒的标志,而是按照传统,一面为君王肖像,一面是纹章或圣母像(插二图3).关于硬币图案,仅在硬币协定第九条中涉及对30克莱采币的统一图案规定:"……为了更好地区别于早先的选侯的和其他地方的价值较低的半古尔登,这些半古尔登上普遍有各自皇帝或国王的至高无上的尊贵的头像,且应在硬币上有斜的正方形图案……".即各邦国铸造的30克莱采,正反面应该各有一个正菱形方框.这原本是奥地利的传统:最早在1694年就铸造了有正菱形框图的1/4 塔勒(30克莱采)硬币,在协定塔勒之前的1740年代,有这种图案的30克莱采币亦在奥地利大量铸造.作为当时经济实力较强的邦国,奥地利希望自己的这一传统传播到其他邦国.但实际除奥地利自己外遵守者寥寥无几.更有甚者,巴伐利亚,符腾堡,伯兰登堡一安斯巴赫,纽伦堡等几个邦国自60年代末开始,陆续把这种框图用在了20协定克莱采币上.根据硬币协定,30克莱采的成色比20克莱采的高,但用肉眼难以分辨,而在中蓐曳带--..直径大小上又和20克莱采币相差无几,所以这样在日常流通中常出现30和20克莱采两种硬币混淆的情况(插二图4).一些不法商贩开始改刻20克莱采币为30克莱采,有的甚至把20克莱采的"2"字划乱,冒充30克莱采使用.由于各邦国铸造的协定硬币是可以相互通用,因此奥地利深受其害,终于宣布这种有框图的20克莱采在奥地利境内为非法, 禁止流通.而巴伐利亚等邦国采取的办法则相反,不再铸造(或者根本就从未铸造过)30克莱采币,让小面值的20克莱采币继续流通.表3是巴伐利亚的两个主要铸币厂:慕尼黑铸币厂于1765年和安贝格铸币厂于1763/64年的5种协定硬币的铸造量.以此为例可以窥见当时几种协定硬币的实际铸造情况.1塔勒主币的铸造量最大,20和10克莱采其次,其数量虽然比1塔勒币少得多,但根据当时的购买力,这两种最低面值的协定硬币却是南德意志地区H常生活中的主要流通货币.1/2塔勒币除奥地利外在多数邦国历来铸造得不多.30克莱采币由于前述的原因,只在1754和1756年铸造了很少一点.其他邦国30克莱采产量也很低.只有奥地利有菱形框图的产量较大.表3巴伐利亚两个铸币厂公布的几种协定硬币的铸造量慕尼黑铸币厂(1765)安贝格铸币厂(1763/64)1塔勒l550ooo3584551/2塔勒225023030克莱采20和1O克莱采6918O37347协定塔勒中的贸易币及玛丽亚一特蕾莎塔勒在协定塔勒家族中,比较特殊的是以协定纯度铸造的贸易币.18世纪以来,地中海东部各国对中南欧诸国贸易往来逐渐增多,对塔勒一类的大型银币的需求日趋旺盛.历史上由于奥地利和奥斯曼帝国长达百余年的战争,许多l7,l8世纪的奥地利塔勒作为战利品流人东方,因此在奥斯曼和东方诸国,奥地利塔勒有着良好的民众接受基础.1741 年奥地利首次铸造有玛丽亚一特蕾莎头像的塔勒硬币,因其女性形象更加具有亲和力,而在黎凡特地区(这里指地中海东部诸国,包括叙利亚,黎巴嫩等在内的自希腊到埃及的地区)大受欢迎,50年代以后协定塔勒开始有边铭,更有利于防止银币被剪边,因此玛丽亚一特蕾莎塔勒逐渐成为黎凡特地区的主要贸易货币之一.1765年,玛丽亚一特蕾莎的丈夫,德意志帝国皇帝弗朗茨一世突然去世.同年奥地利开始铸造玛丽亚一特蕾莎披寡妇面纱形象的塔勒.习惯了原先女王形象的黎凡特地区商人们最初拒绝接受这种新头像的塔勒.不得已之下,奥地利决定在辖下的京茨堡(Gtinzburg)铸币厂铸造一种没有女王头像的塔勒硬币,币面只有经典的协定塔勒文字AD NORMAMCONVENT.这种无头像的塔勒和有寡妇头像的塔勒同时铸造和投放黎凡特市场. 时间改变一切,到1767年人们已逐渐习惯和接受了有寡妇头像的塔勒硬币,而京茨堡的无头像塔勒一直在市场上吃不开,因此只在1766和1767两年生产了少量(插三图5). 1780年玛丽亚一特蕾莎去世后,由于其塔勒在贸易中极受欢迎,奥地利继续使用1780年的模具在维也纳和京茨堡两个铸币厂生产用于贸易的塔勒.1805年京茨堡并入巴伐利亚后剩下维也纳单独生产,此后此塔勒在世界各地广泛铸造和流通至20世纪.鉴于铸造贸易银币的利润,其他邦国也曾铸造自己的贸易协定塔勒.如巴伐利亚也。

1五数指哪五个数?(1)最小值(又称为:Min,0%);(2)第1四分位数(又称为:下四分位数,Q1,25%Percentile,FirstQuartile,LowerQuartile);意思指有25%的数小于等于第1四分位数。

(3)中位数(又称为:Q2,50%Percentile,SecondQuartile,Median);--中间位置的数(4)第3四分位数(又称为:上四分位数,Q3,75%Percentile,ThirdQuartile,UpperQuartile);(5)最大值(又称为:Max,100%)2箱须图(BoxWhiskerPlot)又称箱形图,箱线图(BoxPlot)是展示五数概括的图形。

图1和图2、图3都是箱须图或箱形图,或箱线图。

箱子(Box),指Q1和Q3组成的像箱子一样的部分。

线,指中间的中位数这根线。

须,Whisker指两头的须,#001分布中心是中位数注:一组数字的分布中心看什么值取决于数据分布,如果是对称分布,平均值=中间位置的数。

如果是非对称分布(skewed),平均值<>中间位置的数。

这时候主要看中位数来表示该组数字的分布中心。

#002幅度描述幅度的则是Q1和Q3的距离(IQR),显示出中间部分数据的分散情况。

(Q3-Q1)/2来描述分布的幅度而箱线图的两端(最大值和最小值)则显示出整组数据的分散情况。

3分位数(Quantile),中位数(Median),四分位数(Quartile),异常值(Outliers)(1)分位数(Quantile):把一组按照升序排列的数据分割成n个等份区间并产生n-1个等分点后每个等分点所对应的数据。

按照升序排列称作第一至第n-1的n分位数。

(注:如果等分点在其左右两个数据的中间,那么该等分点所对应的数就是其左右两数的平均数)分成四等份,每份1/4,称之为四分位数Quartile。

兰伯奥斯古模型表达式

兰伯奥斯古模型表达式

兰伯奥斯古模型表达式兰伯奥斯古模型,又称为兰伯奥斯古方程,是经济学中用来描述产出与就业水平之间关系的经济模型。

它的表达式为Y = C + I + G + (X - M),其中Y表示国民收入或产出,C表示消费支出,I表示投资支出,G表示政府支出,X表示出口,M表示进口。

在兰伯奥斯古模型中,国民收入或产出的计算是基于四个主要的支出项:消费支出、投资支出、政府支出和净出口。

消费支出是指个人在消费商品和服务上的支出,投资支出是指企业在购买资本物品上的支出,政府支出是指政府在公共项目和服务上的支出,而净出口是指出口减去进口的差额。

这个模型的核心思想是,国民收入或产出的水平取决于上述四个支出项的总和。

当消费支出、投资支出、政府支出或净出口中的任何一个发生变化时,国民收入或产出也会相应地发生变化。

例如,当消费支出增加时,国民收入或产出也会增加,反之亦然。

兰伯奥斯古模型的表达式中,消费支出占据了很重要的位置。

消费支出可以通过多种方式来计算,其中一种常用的方法是基于消费函数。

消费函数描述了消费支出与国民收入之间的关系,通常采用线性函数的形式,表达式为C = c + mY,其中c表示固定消费支出,m表示边际消费倾向。

除了消费支出,投资支出也是决定国民收入或产出水平的重要因素。

投资支出受到多种因素的影响,如利率、预期收益率和政府政策等。

当投资支出增加时,国民收入或产出也会增加,因为更多的投资意味着更多的经济活动和就业机会。

政府支出是由政府决定和控制的。

政府支出可以用于基础设施建设、教育、医疗保健等公共项目和服务,以促进经济增长和就业机会的增加。

当政府支出增加时,国民收入或产出也会增加,因为政府支出会刺激经济活动和需求。

最后一个支出项是净出口,即出口减去进口的差额。

净出口受到国际贸易条件和汇率等因素的影响。

当净出口增加时,国民收入或产出也会增加,因为更多的出口意味着更多的外汇收入和经济增长。

总的来说,兰伯奥斯古模型提供了一种理解经济增长和就业水平的框架。

旺策尔三等分角结论译文

旺策尔三等分角结论译文【最新版】目录1.引言:古希腊三大几何难题的背景和智者学派2.旺策尔的证明方法3.三等分角的概念和证明过程4.结论:三等分角不可能用尺规作图5.总结:几何难题对数学和哲学的影响正文1.引言:古希腊三大几何难题的背景和智者学派古希腊三大几何难题是指化圆为方、倍立方和三等分角。

这些难题最早由古希腊的智者学派提出,这个学派以诡辩著称,其代表人物包括希比阿斯、安提丰和普罗泰格拉等。

在当时,几何学非常流行,哲学家和数学家常常将几何学应用于他们的研究和思考中。

2.旺策尔的证明方法旺策尔(Wantzel)是一位德国数学家,他在 19 世纪中叶对这三大几何难题进行了深入研究。

他通过严密的数学证明,得出了三等分角不可能用尺规作图的结论。

3.三等分角的概念和证明过程三等分角,即把一个角分成三个相等的部分。

旺策尔在证明过程中,首先假设存在一个角 A,可以被分成三个相等的部分,即∠B=∠C=∠D。

然后,他通过一系列几何变换和数学推理,证明了在这种情况下,必然存在一个正方形,其面积等于已知圆的面积。

但这与另一个著名的几何定理——化圆为方定理相矛盾。

因此,旺策尔得出结论:三等分角不可能用尺规作图。

4.结论:三等分角不可能用尺规作图根据旺策尔的证明,古希腊三大几何难题中的三等分角问题被证明不可能用尺规作图解决。

这一结论对数学界产生了深远的影响,也让人们更加认识到几何学和数学的严谨性和挑战性。

5.总结:几何难题对数学和哲学的影响古希腊三大几何难题不仅推动了几何学的发展,还对哲学和数学产生了深远的影响。

这些难题促使数学家们不断探索和创新,推动了数学的发展。

雅思阅读段落信息搭配题之联想法

雅思阅读段落信息搭配题之联想法

雅思阅读段落信息搭配题之联想法段落信息搭配题是雅思阅读中综合难度最高的一种题型,也让很多考生头疼不已,经过深入研究,老师在本篇给广大考生介绍一下如何运用联想法来进行解题。

一、抽象变具体段落信息搭配题的题干信息大多包含比较抽象、概括的名词,因此定位词很不明显,在原文中也不显眼。

但是这些抽象名词也往往是原文具体化名词的改写词,即题目信息是原文的概括化,这种情况我们称为抽象名词具体化。

这需要我们看到抽象名词时进行联想,把它具体化。

以下有一些高频的抽象名词具体化的例子:(1)Cost/Finance/Funds等表金钱的抽象名词——对应原文金钱数字符号考生在看到题干中含有Cost/Finance/Funds等表金钱的抽象名词,联想到一定是和金钱数字有关,应该先去扫读原文中带有金钱符号的数字,而带有金钱符号的数字往往是非常好找的。

例:剑七Test2 Passage2 第14题题目:ACost Involved in Purifying Domestic Water分析:看到关键词cost, 立马寻找全文是否有带有金钱符号的数字。

扫读过后发现文章D段和E段都有,而E段数字最多,所以从E段看起。

在E段第二行找到定位句:“£23m for the removal of the bug cryptosporidium from drinking water by water companies.”去除removal和purify改写,花费是£23m, 快速得出答案。

(2)Proportion/Rate/Percentage等表比例的抽象名词——对应原文带有百分比的数字考生们在看到题干中含有Proportion/Rate/Percentage等表示比例的抽象名词时,可以联想到跟百分比有关,直接先去找带有百分比的数字。

例:剑九Test2 Passage1 第6题题目:The Estimated Proportion of Children in New Zealand with Auditory Problems分析:看到关键词proportion, 直接寻找百分比数字,扫读全文,发现只有A 段有。

FranciosCusset unfolds his writing in the Academic Enclave in a way that tries to draw a trajectory of American higher education. This trajectory ultimately points to the intrinsic ambiguity that lies at the heart of American university system, the confusion of the real characteristic of American education: whether it is isolated from or closely tied to society?As any other discussions raised by social discourses, this question of American education has its dual character. Although Cusset does not live in America, he is critical enough to notice this duality, as revealed by what he points out “although [American university] is separated from civil society, the university nonetheless maintains a closer link with American political society”(38). With this thought-provoking insight from Cusset, I’m going to analyze the legitimacy of Cusset’s duality from a historical point of view.As it is already mentioned, Cusset points out that there is a duality in the role American university plays in the society. It seems that Cusset reveals the American university from the perspective of both “civil society” and “political society.” In order for us to understand the insight of Cusset, we have to mine into the concept of “political society” and “civil society.” The use of these two terms can be traced back to the political philosopher John Locke, who uses them synonymously. A political society, according to Locke, is a system that men voluntarily entered because of consent on social contract. Because of this consent by all, political society, to some extent, can be seen as the aggregate of all sectors in our society, such as government, business, etc. On the other hand, civil society is often understood as family and private sphere, which is considered the third sector and separated from businessand government. From this respect, it is appropriate to consider civil society as a subset of political society. If this is true, it seems that when Cusset concludes that American university is separated from the society, whi le being the “dramatic relay point” of political society, he has made a logical mistake. However, in order to understand correctly Cusset’s argument, we have to consider the historical background and Cusset’s quotation of Bill Readings.“Bill Readings notes in summarizing the arrival of this ‘posthistorical university’ without any referent-since here excellence itself is, in this logic, a notion with no content”(45). Cusset quotes this phrase by Bill Readings to demonstrate the utilitarian character of “posthistorical university,” which is referred to by Cusset as American university under “corporate culture”. Cusset points out, with Readings word, that American university has become the university of excellence. This university of excellence is so good at absorbing and integrating even what would have threatened its values that it has become nothing more than a machine operated by the market. In other words, university in general has transformed from a site to foster unified national culture into the industry of corporations. According to Cusset, this transformation can be summarized by “learn to earn.” This transformation is embedded in the historical background. The space race that has been given birth by the cold war with USSR, the federal funds for research between 1942 and 1945 all reinforce this transformation. Amongst all of these historical factors, the establishment of what Clyde Barrow calls “military-academic complex” is the one which brings the “civil society” into “political society.” Despite the fundsprovided to university by big corporations, which tends to extract American university out from the civil society and the goal of fostering an unified national culture, Roosevelt’s New Deal forces professors to declare loyalty to government. After WW2, the emphasis on nuclear physics has made the monopolistic role of government on technology increasingly imperative. Under this historical and social background, the political society has gradually breaks away from the civil society, integrating with the government and corporate culture. It seems that the Americna university’s involvement in the 19th century Big Projects such as gene pool mapping has build a close connection with the society, but by no means is this a connection to the formation of a public intellectual field represented by civil society. American university has been incorporated into the corporate culture to serve the interest of political society specifically. As a result, it isn’t unexpected for Cusset to conclude that “the social isol ation of the university was paradoxically reinforced, whereas the new economic and professional realism might have led one to expect the opposite. “Instead of logical contradiction, it is critical for Cusset to consider the American higher education system is both isolated and closely tied to society.。
