In the case of a resistor, the voltage-current relationship is given by Ohm’s law, which states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance. 就电阻来说, 电压—电流的关系由欧姆定律决定。欧姆定律指出:电阻两端的 电压等于电阻上流过的电流乘以电阻值。 2]It may be that the inductor voltage rather than the current is the variable of interest in the circuit. 或许在电路中,人们感兴趣的变量是电感电压而不是电感电流。 Viewed in this light, it will be found that the analysis of three-phase circuits is little more difficult than that of single-phase circuits. 这样看来,三相电路的分析比单相电路的分析难不了多少。 At unity power factor, the power in a single-phase circuit is zero twice each cycle. 在功率因数为 1时,单相电路里的功率值每个周波有两次为零。 It should be noted that if the polarity of point Awith respect to N ( is assumed for the positive half-cycle, then when used in the same phasor diagram should be drawn opposite to, or 180? out of phase with, . 应该注意,如果把 A 点相对于 N 的极性(定为正半周,那么在用于同一相量图中时就应该画得同相反,即相位差为 180?

(完整版)医学专业英语翻译及答案
Chapter 1 Passage 1 Human Body In this passage you will learn: 1. Classification of organ systems 2. Structure and function of each organ system 3. Associated medical terms To understand the human body it is necessary to understand how its parts are put together and how they function. The study of the body's structure is called anatomy; the study of the body's function is known as physiology. Other studies of human body include biology, cytology, embryology, histology, endocrinology, hematology, immunology, psychology etc. 了解人体各部分的组成及其功能，对于认识人体是必需的。研究人体结构的科学叫解剖学；研究人体功能的科学叫生理学。其他研究人体的科学包括生物学、细胞学、胚胎学、组织学、内分泌学、血液学、遗传学、免疫学、心理学等等。 Anatomists find it useful to divide the human body into ten systems, that is, the skeletal system, the muscular system, the circulatory system, the respiratory system, the digestive system, the urinary system, the endocrine system, the nervous system, the reproductive system and the skin. The principal parts of each of these systems are described in this article. 解剖学家发现把整个人体分成骨骼、肌肉、循环、呼吸、消化、泌尿、内分泌、神经、生殖系统以及感觉器官的做法是很有帮助的。本文描绘并阐述了各系统的主要部分。 The skeletal system is made of bones, joints between bones, and cartilage. Its function is to provide support and protection for the soft tissues and the organs of the body and to provide points of attachment for the muscles that move the body. There are 206 bones in the human skeleton. They have various shapes - long, short, cube - shaped, flat, and irregular. Many of the long bones have an interior space that is filled with bone marrow, where blood cells are made. 骨骼系统由骨、关节以及软骨组成。它对软组织及人体器官起到支持和保护作用，并牵动骨胳肌，引起各种运动。人体有206根骨头。骨形态不一，有长的、短、立方的、扁的及不规则的。许多长骨里有一个内层间隙，里面充填着骨髓，这即是血细胞的制造场所。 A joint is where bones are joined together. The connection can be so close that no movement is possible, as is the case in the skull. Other kinds of joints permit movement: either back and forth in one plane - as with the hinge joint of the elbow - or movement around a single axis - as with the pivot joint that permits the head to rotate. A wide range of movement is possible when the ball - shaped end of one bone fits into a socket at the end of another bone, as they do in the shoulder and hip joints. 关节把骨与骨连接起来。颅骨不能运动，是由于骨与骨之间的连接太紧密。但其它的关节可允许活动，如一个平面上的前后屈伸运动，如肘关节；或是绕轴心旋转运动，如枢轴点允许头部转动。如果一根骨的球形末端插入另一根骨的臼槽里，大辐度的运动（如肩关节、髋关节）即成为可能。 Cartilage is a more flexible material than bone. It serves as a protective, cushioning layer where bones come together. It also connects the ribs to the breastbone and provides a structural base for the nose and the external ear. An infant's skeleton is made of cartilage that is gradually replaced by bone as the infant grows into an adult. 软骨是一种比一般骨更具韧性的物质。它是骨连结的保护、缓冲层。它把肋骨与胸骨连结起来，也是鼻腔与内耳的结构基础。一个婴儿的骨骼就是由软骨组成，然后不断生长、
财务管理专业英语 句子及单词翻译
Financial management is an integrated decision-making process concerned with acquiring, financing, and managing assets to accomplish some overall goal within a business entity. 财务管理是为了实现一个公司总体目标而进行的涉及到获取、融资和资产管理的综合决策过程。 Decisions involving a firm’s short-term assets and liabilities refer to working capital management. 决断涉及一个公司的短期的资产和负债提到营运资金管理 The firm’s long-term financing decisions concern the right-hand side of the balance sheet. 该公司的长期融资决断股份资产负债表的右边。 This is an important decision as the legal structure affects the financial risk faced by the owners of the company. 这是一个重要的决定作为法律结构影响金融风险面对附近的的业主的公司。 The board includes some members of top management(executive directors), but should also include individuals from outside the company(non-executive directors). 董事会包括有些隶属于高层管理人员(执行董事)，但将也包括个体从外公司(非执行董事)。 Maximization of shareholder wealth focuses only on stockholders whereas maximization of firm value encompasses all financial claimholders including common stockholders, debt holders, and preferred stockholders. 股东财富最大化只集中于股东，而企业价值最大化包含所有的财务债券持有者，包括普通股股东，债权人和优先股股东。 Given these assumptions，shareholders’ wealth maximization is consistent with the best interests of stakeholders and society in the long run。 根据这些假设，从长期来看，股东财富最大化与利益相关者和社会的最好利润是相一致的。 No competing measure that can provide as comprehensive a measure of a firm’s standi ng. Given these assumptions, shareholders’ wealth maximization is consistent with the best interests of stakeholders and society in the long run. 没有竞争措施，能提供由于全面的一个措施的一个公司的站。给这些臆说，股东'财富最大化一贯不比任何人差项目干系人项目利益相关者的利益，社会从长远说来。 In reality, managers may ignore the interests of shareholders, and choose instead to make investment and financing decisions that benefit themselves. 在现实中，经理可能忽视股东的利益，而是选择利于自身的投资和融资决策。 Financial statements are probably the important source of information from which these various stakeholders(other than management) can assess a firm’s financial health. 财务报表可能是最重要的信息来源，除管理者以外的各种利益相关者可以利用这些报表来评估一个公司的财务状况。 The stockholders’ equity section lists preferred stock, common stock and capital surplus and accumulated retained earnings. 股东权益列示有优先股，普通股，资本盈余和累积留存收益。 The assets, which are the “things” the company owns, are listed in the order of decreasing liquidity, or length of time it typically takes to convert them to cash at fair market values, beginning with the firm’s current assets. 资产，也就是公司拥有的东西，是按照流动性递减的顺序或将它们转换为公允市场价值所需要的时间来排列的，通常从流动资产开始。The market value of a firm’s equity is equal to the number of shares of common stock outstanding times the price per share, while the amoun t reported on the firm’s balance sheet is basically the cumulative amount the firm raised when issuing common stock and any reinvested net income(retained earnings). 公司权益的市场价值等于其发行在外的普通股份数乘以每股价格，而资产负债表上的总额则主要是公司在发行普通股以及分配任何再投资净收益（留存收益）时累积的数额。 When compared to accelerated methods, straight-line depreciation has lower depreciation expense in the early years of asset life, which tends to a higher tax expense but higher net income. 与加速折旧法相比,直线折旧法在资产使用年限的早期折旧费用较低，这也会趋向于较高的税金费用和较高的净收入。 The statement of cash flows consists of three sections:(1)operating cash flows,(2)investing cash flows, and(3)financing cash flows. Activities in each area that bring in cash represent sources of cash while activities that involve spending cash are uses of cash. 该声明现金流量表包含三个部分:(1)经营现金流,(2)投资的现金流,(3)融资现金流。在每个地区活动带来现金来源的现金而代表活动涉及到花钱是使用现金 Financing activities include new debt issuances, debt repayments or retirements, stock sales and repurchases, and cash dividend payments. 筹资活动,包括发行新债券，偿还债务，股票销售和回购，以及现金股利支付。 Not surprisingly, Enron’s executives had realized some $750 million in salaries, bonuses and profits from stock options in the 12 months before the company went bankrupt. 毫不奇怪, 公司破产前的十二个月里，安然的高管们实现了7.5亿美金的工资、奖金和股票期权利润。First, financial ratios are not standardized. A perusal of the many financial textbooks and other sources that are available will often show differences in how to calculate some ratios. 首先,财务比率不规范。一个参考的许多金融教科书及来源,可将经常表现出差异如何计算一些率。 Liquidity ratios indicate a firm’s ability to pay its obligations in the short run. 流动性比率表明公司的支付能力在短期内它的义务。 Excessively high current ratios, however, may indicate a firm may have too much of its long-term investor-supplied capital invested in short-term low-earning current assets. 当前的比率过高,然而,可能表明,一个公司可能有太多的长期 investor-supplied资本投资于短期low-earning流动资产 In an inflationary environment, firms that use last-in, first-out(LIFO)inventory valuation will likely have lower current ratios than firms that use first-in, first-out(FIFO). 在一个通货膨胀的环境下,企业选择使用后进先出法对存货计价的公 司比采用先进先出法的公司有一个低的流动比率。 The cash ratio is too conservative to accurately reflect a firm’s liquidity position because it assumes that firms can fund their current liabilities with only cash and marketable securities. 流动比率太稳健不能正确反映一个公司的流动性状况，因为在这一比率假定公司仅仅用现金和有价证券就可以偿还流动负债。 Debt management ratios characterize a firm in terms of the relative mix of debt and equity financing and provide measures of the long-term debt paying ability of the firm. 描述一个公司债务管理比率从相对的混合的债务和股权融资的措施, 提供长期偿债能力的公司。 Total capital includes all non-current liabilities plus equity, and thus excludes short-term debt. 资本总额包括所有非流动负债加上股本,从而排除短期贷款。 Net profit margins vary widely by the type of industry. 有着很大的不同,其净利润为典型的产业。 Note that earnings before interest and taxes, rather than net income, Is used in the numerator because interest is paid with pre-tax dollars, and the firm’s ability to pay current interest is not affected by taxes. 注意,分子中用的是息税前利润而不是净收入，这是因为利息是税前支付的，公司支付现金利息的能力不受税收的影响。 Managers should analyze the tradeoff between any increased sales from a more lenient credit policy and the associated costs of longer collection periods and more uncollected receivables to determine whether changing the firm’s credit sales policy could increase shareholder’s we alth. 管理者应该分析权衡增加的销售从一个更为宽松的信贷政策和相关费用较长的周期和更多的应收账款收集来决定是否改变公司的信用销售的政策可能会增加股东的财富。 If the receivables collection period exceeds a firm’s credit terms this may indicate that a firm is ineffective in collecting its credit sales or is granting credit to marginal customers. 如果应收账款采集时间超过公司的信用条款这也许说明了企业信用销售收集它无效或给予客户信用边缘。 A low, declining ratio may suggest the firm has continued to build up inventory in the face of weakening demand or may be carrying and reporting outdated or obsolete inventory that could only be sold at reduced prices, if at all. 一个低税率、下降率可能显示这个公司已经持续不断地加强库存面对需求不断减弱或可能携带和报告过期或过时的库存,只能减价出售。Thus, the operating profit margin, which indicates the operating profit generated per dollar of net sales, measures t he firm’s operating profitability before financing costs. 因此,经营利润,预示着美元营业利润产生的净销售额,公司的经营利润措施在融资成本。 If the firm’s fixed assets are old and have been depreciated to a low book value, and the assets have not lost their productive ability, the low figure in the denominator will inflate ROA. 如果公司固定资产比较旧,分母的减少会是ROA折旧到低的账面价值，但是资产并没有失去生产能力。 Return on common equity(ROCE) focuses on just the return to common shareholders and is computed by removing the dividends to preferred shareholders from net income and dividing by the capital provided by common shareholders. 普通股权益报酬率仅仅关注普通股股东的报酬率，用净收入扣除优先股股利除以普通股股东提供的资本计算得到。 Dividend yield represents parts of a stock’s total return; another part of a st ock’s total return is price appreciation. 代表部分股息率的股票总回报;另一部分是一个股票的总回报价格上涨。 In fact, of all the concepts used in finance, none is more important than the time value of money, also called discounted cash flow(DCF) analysis. 事实上,财务上所有的概念中，货币时间价值是最重要的，也称作是折现调整现金流量折价分析。

Fashion,which is as old as time and as new as tomorrow,is one of the most powerful forces in our lives .It influences what we wear,the way we talk,the foods we eat,the way we live,how and where we travel,what we travel,what we look at,and what we listen to.Fashion is what lead us todiscard a product that is still useful but is no longer ―in‖.It is also what makes us sometimes wear more clothes than we may actually need,and sometimes less than is needed to product us from the ccold or the sun. 流行是这样一种事物，是我们抛弃了还可以使用，但不再时髦的产品。有时候使我们穿比我们真正穿的衣服多，有时候比我们穿抵御严寒酷暑的少。 If there is one absolute constant pertaining to fashion,it is the fact that it is always changing-sometimes rapidly,sometimes slowly,but it is never static or dormant.This element of change is recognized in the definitions of fashion itself cited earlier,by the use of such words as ―prevailing‖or ―a given period of time.‖To ignore the element of change is like looking at a still photograph in place of a motion picture.The still tells you what is happening here and now ;the motion picture shows you what came before and what may lie ahead. 如果存在着一种符合流行的绝对永恒，那就是流行是永远变化着的这一事实，（这种变化）时快时慢，但绝不会固定下来或呈休止状态。 “Fashion is a social phenomenon which reflects the same continuing change that rides through any given age .‖Change in fashion ,he emphasized,‘correspond with the subtle and often hidden network of forces that operate on society……’ “流行是一种社会现象，它反映了任何特定年代同样都要经历的持续变化。‖他强调说：“流行变迁与那些作用于社会的影响力量所具有的微妙，而又常常是暗藏着的系统是一致的。”It is only in restrospect that fashion changes seem marked or sudden .Autually ,they come about as a result of a series of gradual shifts from one season to the next.For example ,when women’s skirts began inching up from midcalf in the 1960s,this gradual shortening was not particularly noticeable at first .It was only when skirts moved thigh-high,in the form of minis and micro-minis ,that people took notice of the approaching extreme.Similarly,when men begin to abandon ultrannarrow ties and suit lapels in favor of more and more width,the changs are not noticed at first. 只有当追溯过去的时候，流行的变迁才显得特别引人注目或突然，实际上，这些变迁的发生是从一个季节到另一个季节的一系列逐渐变化的结果。例如，女裙的逐渐变短的时候并没有被注意到，。 ………………………………………………………… Color can be the basis for a whole group or line .It is the first element to which consumers respond .People relate personally to color,usually either selecting or rejecting a garment beccause of its ccolor appeal.Therefore,designers must cconsider their customers and provide colors that are both appealing and flattering. 色彩是整个款式系列中的基本要素，它是能够引起顾客回应的第一要素。人们把色彩和个人联系起来，他们往往根据颜色来选择或拒绝一件衣服，因此设计师必须考虑他们的顾客，并且提供出令他们喜爱和满意的色彩，消费群体。 In clothing,neutrals such as beige,tan,brown,white ,gray,and black are even more popular than the ccolors just mentioned.The reason is probably that they present a pleasing background for the wearer without completing for attention. Neutrals are part of every season‖s fashion picture ,as either a strong fashion statement or a way to round out a color story. 在服装中，中色调例如灰中色，深褐，褐色，白灰和黑色，甚至还有比刚刚提到的更多的
