度量

Letbe a compact metric space, f: X→X a continuous map, and K(X,H a compact metric space consisting of all nonempty compact subsets of X.

设为紧致度量空间， f： X→X连续， K(X，H是 X所有非空紧致子集构成的紧致度量空间。

And then the approach is extended to continuous random variable. The optimal rule of general group decision-making is drawn by the new approach, which turns out to be a generalized weighted majority rule. The weight allocated to a decision-maker should be equal to the information quantity he provides.

鉴于Boltzmann—Shannon熵难以直接用来度量群体决策中信息的变动情况，我们提出了一种对离散随机变量的新的信息度量方法，证明了该信息函数仍然满足等状态时信息量最小这一性质；随后将其推广到了连续随机变量。

First, a method for calculating semantic likelihood between two phrase is carried out. then use the likelihood to determine the title row or column of the table, the correlation between titles and fields is determined at the same time. base title of the table, a simply method is presented which can be used to calculate correlativity between this table and what we wanted to extract.

首先提出了一种短语语义相似度的度量方法，然后利用短语语义的相似度确定表格标题行，并对表格行与抽取字段的对应关系进行计算，最后计算表格的整体语义，度量该表格与所要抽取的内容有多大相关度。

We show that there are 'many' compacta admitting completely scrambled homeomorphisms, which include some countable compacta, the cantor set and continua of arbitrary dimension.

并说明了"许多"紧度量空间其上存在完全混沌的系统，这些空间包括一些可数的紧度量空间、康托集和任意维的连续统。

It is shown there are"many"compacta admitting compeletly chaotic systems, which include some countable compacta, the cantor set and continua of arbitrary dimension.

构造了"许多"紧度量空间其上存在完全混沌的系统，这些空间包括一些可数的紧度量空间、康托集和任意维的连续统。

We focus our analysis on the basic utilization metrics of the service network (passenger load and revenue and deadhead flight levels) from which we can derive other significant metrics.

把我们的分析的基本利用度量(旅客的服务网络负载和收入水平和deadhead航班)我们从中得到其他重要度量。

At many occasions they arise quite natu-rally.For example,they appear in the Iwasawa decomposition of the isometry group ofa non-compact Riemannian symmetric space.Also,every connected homogeneous Rie-mannian manifold of non-positive sectional curvature can be represented as a connectedsolvable Lie group with a left-invariant Riemannian metric.

它们出现在非紧致黎曼对称空间的等距群的Iwasawa分解中；任一非正截面曲率的连通齐性和黎曼流形可以表为带有左不变黎曼度量的连通可解李群等，带有左不变黎曼度量的幂零及可解李群的微分几何，调和分析和谱几何是重要的研究课题。

本文在分析了安全系统软件的安全性和风险度量概念的基础上，详细讨论了黑箱条件下的软件风险度量等问题。

A method of similarity measurement is discussed based on the improvement of quadric form distance function.

在改进加权二次型相似性度量方法的基础上，提出了相应的主色多特征相似性度量方法。

In order to expose more exactly of the market risk faced by financing institutions, and manage risk more deeply and completely, This article expands research in the following aspects: multivariate abnormal distribution family, the measurement of correlation function in the portfolio selection and Copula function.

为了能更准确地反映金融机构面临的市场风险，进行深层次的、全面的管理金融风险，本文最后从以下几方面展开了风险价值度量方法的研究：多元非正态分布族，投资组合中相关性度量方法及Copula函数。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
