We first state general linear model, ridge-type estimator and general ridge-type estimator, and the constraint biased estimator. And then, we introduce some basic theory about matrix and some conclusion about the admissibility of estimator in Gauss-Markov model. In the third chapter, we discussion several equivalent characterization of the best linear unbiased estimation, we proved that admissible characterization of admissible of linear estimation is as conditional general ridge-type estimation in general linear model. A necessary and sufficient condition that homogeneous linear estimator is admissible estimator is obtained.

本文首先概述了一般线性模型，岭估计及约束岭估计的发展历史和研究现状，在第二章介绍了矩阵的一些基本知识和可容许性的一些基本结论，第三章讨论了一般线性模型最佳线性无偏估计的几个等价条件，以及线性估计的可容许性特征，得到了一般线性模型的可容许线性估计均具有条件广义岭估计的形式，给出了一个齐次线性估计为可容许估计的充分必要条件。

The main research work in this paper is as follows:(1) A detailed analysis about the theory of the SVM is given in the paper. And one framework of the Network Fault Diagnosis System based on SVM in network Application Layer is proposed. The handle process and the function, mechanism of the components of this framework are discussed in the paper.(2) When the size of the training sets is uneven, the classification error rate of the results based on the traditional C-Support vector machine is undesirably biased with the less sample in the training sets.

由于故障诊断是有限样本学习问题在实际中的体现，因此可以将支持向量机方法引入到网络应用层的故障诊断中来，本文涉及的内容主要包括：(1)详细深入的分析了支持向量机的理论特点及其与网络应用层故障诊断的关联，并就构建的基于支持向量机的网络应用层故障诊断模型，阐述了该模型的处理流程以及其中各个模块的功能、机制。
