查询词典 utility

I.e. the utility of the books are almost the same , so it is a wise choice to choose second hand books. And in the aspect of consumer's surplus, the consumers expect one book to be lower than, say, 30 Yuan, so if he buys the book for 10yuan, he gets extra 20yuan as the so called consumer's surplus.

话说回来，从机会成本的角度来看，因为旧书与新书大部分相差不大，基本不会影响到学生的书籍阅读（即书的效用是几乎一样的），学生在旧书摊买书的机会成本相对较小，于是学生们是会选择到旧书摊买书的。

As we talked about bilateral relations, I mentioned the utility of a permanent point of contact.

当我们谈到双边关系时，我提到了设立一个永久接触点所带来的好处。

In order to improve the uplink bandwidth utility, that is, keeping the guard band between conterminous ONU slots as short as possible, as well as avoiding the upstream data collision, OLT must take the RTT of ONU into account, when arranges the start and ending time of ONU's transmission window.

为了提高EPON上行带宽利用率（即尽量缩短相邻ONU时隙之间的保护带长度），同时避免上行数据冲突，OLT在安排给ONU的授权窗口的开始时间和结束时间时，必须要将ONU的距离考虑在内。

In this paper, the connectivity axiom and the continuity axiom in Von Neumann-Morgenstern Rational behavior axioms are weakened. Then, a set of axiom for lattice ordered decision-making behavior, which can describe the decision-making behavior more rationally, is constructed. At last, the relative unique existence theorem for utility function is obtained.

根据偏好关系所具有的格序特征，将Von Neumann-Morgenstern理性行为公理体系中的连通性公理弱化为格连通性公理，并相应地弱化连续性公理，得到了一集能更为合理地描述具有"有限理性"的决策行为的格序决策行为公理体系，构造并证明了在格序决策行为公理体系之下，效用函数的存在惟一性定理。

In this dissertation,Von Numann and Morgenstern Axioms are analyzedagain at first.It is pointed out not only that preference relations are often latticeordered,but also that the transitivity axiom,along with the independence axiomand the continuity axiom is still rational to a high degree,then a new set ofaxioms for lattice-order decision-making behavior is established.At last,relatedsubjects based on lattice in preference theory,utility theory,decision-makingmethods,multiattribute decision-making,and group decision-making are studied.In this way,the lattice-order decision-making theory is framed.Main creativeresults are obtained as follows

本论文重新审视了Von Neumann-Morgenstern理性行为公理体系，对以前学者较少涉及到的连通性公理提出了质疑，指出偏好关系具有格特征，而传递性公理、独立性公理以及连续性公理在很大程度上仍具有合理性，进而创建了格序决策行为公理体系，研究了基于格的偏好理论、效用理论、决策方法、多目标决策以及群决策中的相关问题，初步构建了格序决策理论框架，主要研究成果如下

为了构建低耗能、高连通性、低干扰并具有合理路由的多跳无线网络，应用基于博弈论的网络拓扑结构控制解决方案，为节点设计了一种新颖的收益函数。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
