电气工程及其自动化专业英语 考试题型：选择10*2 单词翻译10*2 短句翻译5*4 长句翻译4*10 Exercise All the simple circuit elements that will be 在下面进行的工作中我们要研究的简单电路元件,可以根据流过元件的电流与元件两端的电压的关系进行分类。例如，如果元件两端的电压正比于流过元件的电流，即u＝ki，我们就把元件称为电阻器。其他的类型的简单电路元件的端电压正比于电流对时间的导数或正比于电流关于时间的积分。还有一些元件的电压完全独立于电流或电流完全独立于电压，这些是独立源。此外，我们还要定义一些特殊类型的电源，这些电源的电压或电流取决于电路中其他的电流或电压，这样的电源将被称为非独立源或受控源。 It must be emphasized that the linear 必须强调的是线性电阻器是一个理想的电路元件；它是物理元件的数学模型。我们可以很容易地买到或制造电阻器，但很快我们发现这种物理元件只有当电流、电压或者功率处于特定范围时其电压——电流之比才是恒定的，并且这个比值也取决于温度以及其它环境因素。我们通常应当把线性电阻器仅仅称为电阻器。只有当需要强调元件性质的时候才使用更长的形式称呼它。而对于任何非线性电阻器我们应当始终这么称呼它，非线性电阻器不应当必然地被视为不需要的元件。 If a circuit has two or more independent 如果一个电路有两个或多个独立源，求出具体变量值（电流或电压）的一种方法是使用节点分析法或网孔分析法。另一种方法是求出每个独立源对变量的作用然后把它们进行叠加。而这种方法被称为叠加法。叠加法原理表明线性电路某个元件两端的电压（或流过元件的电流）等于每个独立源单独作用时该元件两端的电压（或流过元件的电流）的代数和。 The ratio of the phase voltage to the 相电压与相电流之比等于电路的阻抗，符号为字母Z，阻抗是一个具有量纲为欧姆的复数量。阻抗不是一个相量，因此不能通过把它乘以e jωt,并取其实部把它转换成时域形式。但是，我们把电感器看作是通过其电感量L表现为时域形式而通过其阻抗jωL表现为频域形式，电容在时域里为电容量C而在频域里为1/jωc，阻抗是某种程度 上的频域变量而非时域变量。 Both wye and delta source connections 无论是星型连接的电源还是三角形连接的电源都有重要的实际应用意义。星型连接的电源用于长距离电力传输，此时电阻损耗(I2R)将达到最小。这是由于星型连接的线电压是三角形连接的线电压的√3倍，于是,对于相同的功率来说，三角型连接的线电流是星形连接的线电流的√3倍。三角形连接的电源使用在根据三相电源而需要的三个单相电路中。这种从三相到单相的转变用在住宅布线中因为家用照明和设备使用单相电源。三相电源用在需要大功率的工业布线中。在某些应用场合，无论负载是星形连接还是三角形连接并不重要。

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。

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? One problem with electronic devices corresponding to the generalized amplifiers is that the gains, AU or AI, depend upon internal properties of the two-port system. 对应于像广义放大器这样的电子装置,一个问题就是增益 AU 或者 AI ,它们取决于两输入端系统的内部特性。
