Despite the fact that utility is not subject to precise quantification, it is still analytically useful to assume that utility can be represented by cardinal numbers.

尽管事实是效用不受精确数量的影响，从分析角度来讲，假如效用可以用基数来描述，这还是很有用的。

Utility value is the matter agent of environmental economics value,utility value relation assumes catenoid or netlike structure.

效用价值是环境经济价值的物质承担者，效用价值关系呈链状或网状结构。

这个工具主要为财政机构所使用，他们希望在一个给定文档中的校验/计算一个路由选择/运输线数字的校验数位。

Create Self-Extracting EXEs Works with the Chilkat Zip 2 Secure EXE utility to access ZIPs embedded in EXEs created by that utility.

创建自解压exes工程与奇尔卡特邮编2安全的EXE公用事业访问拉链嵌入在exes所创造的说，实用工具。

Properties of efficient portfolios and the efficient frontier to the model are systematically analyzed. Our main results concerning the properties are: every efficient portfolio can be solved by minimizing portfolio risk under a given level of portfolio return or by maximizing portfolio return under a given level of portfolio risk; on the efficient frontier, the risk is a convex and strictly increasing function of the return and the return is a concave and strictly increasing function of the risk; the utility function on the efficient frontier can be expressed as a quasi-concave function of the risk or the return if the investor's utility function is quasi-concave.

从理论上系统地对该模型下的有效投资组合和有效前沿的性质进行了分析，结果表明：每一个有效投资组合可通过在给定期望收益水平的条件下最小化投资组合风险来获得，或者在给定风险水平的条件下最大化期望投资组合收益来获得；在有效前沿上，风险是收益的严格单调递增凸函数，收益是风险的严格单调递增凹函数；当投资者的效用函数是拟凹函数时，则有效前沿上的效用可表达成风险或收益的拟凹函数。

According to the logical approach, the providing of the analysis hypothesis before the model construction is necessary. For example, the hypothesis of rational man and utility identity are for the convenient analysis, the hypothesis that the rich utility is smaller than the poor utility is for the importance of the third distribution.

按照逻辑方法，模型构建之前的分析假设的给出是必要的，比如关于"经济人"假设和效用归一假设等是为了分析的简便而作出的，关于富人效用小于穷人的效用假设是给出了第三次分配的意义所在。

This kind of support,like all government support,requires decisions about the appropriate recipients of funds.decisions based on utility as opposed to lack of utility are straight forward.but a decision among projects none of which has immediate utility is more difficult.the goal of the supporting agencies is the praisable one of supporting"good"as opposed to"bad"science,but a valid determination is difficult to make.generally,the idea of good science tends to BEC ome confused with the capacity of the field in question to generate an elegant theory.

此种资助也与所有政府资助一样，需要决定合适的投资对象。根据某一项目是否有效来做出决策是明确无误的。但是在几个都没有直接效用的项目中，要做出抉择就特别困难。资助机构的目标是支持&好&的科学，而不资助&坏&的科学，那是值得赞扬的。然而要做出正确的抉择却是困难的。人们往往将好科学与该科学是否有能力提出一套完美的理论混淆起来。

This thesis presents a single-phase three-wire photovoltaic energy conversion system. When the proposed system is operating at the maximum power point, the energy is fed to the utility with sinusoidal wave. In low insolation environment, the proposed system operates at the function of active power filter and battery charger. When the utility is fault, the system is disconnected from the utility source.

本文提出一个单相三线式光伏能量转换器系统，使太阳能光伏能量转换器运转於最大功率，将能量以弦波电流送入市电，在无光源时，为主动式电源滤波器的功能，此时可经由市电提供能量对蓄电池充电；当故障时，系统必须与市电解联。
