This thesis has mainly contributed two results in theory: one is that the covariance matrix is not positive definitive if the number of sampling is least than the number of variables, the other is that the covariance matrix of discrete sample is positive definitive if and only if the sum of every random column vector of data matrix is non I-linear combination.

本论文在理论上，主要得出两个新的结果：ⅰ抽样调查中，若样本的个数少于变量的个数则样本协方差矩阵恒为非正定；ⅱ离散型样本协方差矩阵正定的充要条件是样本资料阵的各随机列向量是非I-线性组合。

If you want Windows 2000 in order to speed the resumption of the moment, you can press Ctrl + Alt + Del combination keys, and then click on the "Shut Down" button while holding down the Ctrl, then the system will prompt a pop-up warning:"If you continue, your machine will re-start, unsaved data will be lost, if not absolutely necessary, do not take this step ", click" OK ", then Windows 2000 will be an instant restart and shutdown screen is not displayed.

如果想让Windows 2000以瞬间的速度重启，那么可以按下Ctrl＋Alt＋Del组合键，接着在点击"关机"按钮的同时按住Ctrl，这时系统会弹出警告提示："如果继续，您的机器会重新启动，未保存的数据将丢失，如非绝对必要，请勿采取此步骤"，点击"确定"，那么Windows 2000将会瞬间重启，并不会显示关机画面。

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。

为了能更准确地反映金融机构面临的市场风险，入行深层次的、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 cause of the target fade-out in Neural Network nonuniformity correction scheme for infrared focal plane arraywas studied. Based on analyzing the strength and limitation of edge-directed NN scheme and nonuniformity correction combining one-point calibration and NN-NUC, a new combinational algorithm for nonuniformity correction was proposed.

中文摘要：分析了传统神经网络非均匀性校正算法在空域处理过程中产生目标退化的原因，在总结基于边缘指导的神经网络校正算法与一点定标和神经网络结合的校正算法的基础上，提出了新的组合校正算法。

However, asymmetric Laplace distribution has only 2 parameters and explicit distribution function form, it can fit the data of stock returns well. Consequently it greatly facilitates the calculation of optimal portfolios and the management of financial risk.

非对称拉普拉斯分布有明确的解析表达分布函数，只含有2个参数，能够较好拟合股票收益率分布的尖峰厚尾偏倚特性，给进一步的研究证券投资组合和金融风险管理带来了很大的便利。

Directory has 16 configurations (batch mode build is recommended) that accommodate the various combinations of MFC linkage, Ole/non-Ole, Unicode/MBCS, and debug/release configu

目录有16个配置的适应MFC的联系，奥莱彼得/非奥莱彼得，Unicode的/的MBCS和调试的各种组合/释放配置。

For the monotone class of filters, the robust stability test is similar to that of Kharitonov theorem, which only needs to test four extreme polynomials of the class. However, for the non-monotone class of discrete systems, the test must examine possible combinations of all extreme polynomials.

单调系统簇的稳定性检验与Kharitonov定理的检验类似，只需检验集合中的四个端点或复多项式，而非单调系统需检验所有可能的端点复多项式的组合。

On the portfolio credit risk analysis, this thesis, based on the credit data's scarcity in China, puts forward a nonparametric method to measure the default correlation coefficients between China's listed companies, and then presented a numerical example to show how to use it in practice.

在组合信用风险分析方面，本文在以往研究的基础上，并针对中国信用数据十分稀少的实际情况，提出了一种对中国上市公司间违约相关系数进行度量的非参数方法，最后用一个数值例子来说明这种方法在实际中的应用。

The problem of set partitions in combinatorial mathematics is conside-red, and the following three points are emphasized:(1) the non-recursivealgorithm for computing the number of partitions of an N-Set, P;(2)the algorithm for mapping the partition vector V to the partition sequencenumber D;(3) the algorithm for mapping the partition sequence number Dto the partition vector V.

本文对组合数学中的集合划分问题进行了一些探索，试图回答下面三个问题：①集合划分方法数P的非递归算法，②划分向量V映射到划分序号D的算法，③划分序号D映射到划分向量V的算法。本文以划分的构造树为基础，加以变换，得到数目树和分块树，由此求得P，以及K块划分方法数P_K。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
