今晨已经去函，报50公吨红茶每公吨XXX美元CFR上海净价，装运期为11月和12月，以七月三十日前复到为准。

In chapter one, the background and current situation of the nonlinear operator theory in probabilistic metric spaces are introduced, and the preliminaries of probabilistic metric spaces are given. The main problems studied in the thesis, the expected conclusions and the study and research significance of this thesis are introduced.

第一章，介绍了概率度量空间中非线性算子理论发展的历史背景、现状以及概率度量空间中的预备知识；介绍了本文所研究的主要问题、预期取得的结果以及研究意义。

The nonstandard anslysis theory is used in the κ-saturated nonstandard model, the definition of the quasi-near-standard points in a metric space is given and it is proved that a point in nonstandard metric space is quasi-near-standard point if and only if its monad contained in every *-open ball of some standard point.

在κ-饱和的非标准模型下，采用非标准分析方法，提出了度量空间中的拟近标准点的定义，得到了非标准度量空间中的点是拟近标准点的充要条件是它属于某一个标准点的每一个*-开球，证明了度量空间的非标准完备化恰是该空间的非标准扩张中拟近标准点集的商空间。

By constructing the piecewise linear function from samples, it is able to approximate the measured metric more precisely. Compared with current popular sampling algorithms, FASM algorithm can provide more precise estimation of metric under the same samples. In the condition of retaining the same approximation errors, our adaptive sampling methodology only requires fewer samples, which will save sampling costs considerably during sampling process.

与当前常用的抽样算法相比，在采集相同的样本数量情况下，本文的拟合模型对指标进行的估计更准确、稳定；而在保持相同的拟合误差时，自适应抽样算法则可显著减少所需采集的样本数量，节约数据采集过程的代价。

Similarly, a countable product of metric spaces can be obtained using the following metric

类似的，度量空间的可数乘积可以用如下度量获得

To our entire disappointment,as compared with the total weight of 2 ,000 metric tons stipulated in the contract,we found a short-weight of 45 metric tons.

令我们完全失望的是，与合同规定的2；000公吨总数相比，我们发现短重45公吨。

Chapter 3. Make use of the unified field equation not only deduce the motional equation for matter, but also still have get the spacetime metric of the unified field and spherically symmetry electromagnetic metric.

第三章 利用统一场方程不仅导出物质的运动方程，而且还得到了统一场的时空度规和球对称电磁度规。

Since the commonly-used parameter analysis method is liable to cause the diversity of results in style investment analysis, the method of subdominant ultra-metric space is introduced to the study of style investment. Subdominant ultra-metric space is provided with the exactly defined topology sequence, and corresponded with index hierarchical structure and style.

针对常用的参数分析方法在证券风格投资分析中容易导致结果的差异性问题，提出将亚超度量空间方法引入到风格投资研究中，因为具有准确定义拓扑序列的亚超度量空间与指数分层结构、风格能够一一对应。

Firstly, the distance between stocks are calculated by using prices of stocks, and subdominant ultra-metric space by associating the minimum spanning tree of portfolio. Secondly, the subdominant ultra-metric space to the chart of index hierarchical structure is transformed, and finally the distribution of style is gained. Using sample of Shanghai Stock 50 Index from 2004 to 2007, the demonstration result shows that style of industry is more prominent horizontally, especially in the bank and steel industries. The style of region and cross holding also exists. And after the reform of non-tradable shares, style of industry becomes more obvious vertically and more other styles also occur.

首先利用股票价格计算出股间距离，并采用关联该证券组合的最小生成树优化方法，从而得到亚超度量空间；其次将此亚超度量空间转换成指数分层结构树图，最后得到风格的分布特征。2004~2007年的上证50实证结果表明：横向来看以行业分类的风格较为显著，其中以银行和钢铁也最为明显，此外还有与地区差异、交叉持股相关的风格效应显现；纵向则在股改后行业风格效应更显著，其它的风格也显现得更多。

We introduce a set of real functions H, and use to it to give a fixed point theorem of tother type for complex mappings on complete metric spaces, which improves and generalizes the corresponding results on compact metric spaces or under the condition of weakening compactness obtained by Fisher, Telci and Xu Xiao-li, respectively.

利用引入的实函数类H，在完备度量空间上给出了复合映射的另一种类型的不动点定理，改进并推广了Fisher、Telci和徐晓立等在紧致度量空间上或在弱化紧性条件下得到的相应结果。
