In the fifth chapter, we propose the conditional generalized ridge-type estimator of regression coefficient in restricted linear regression model, and prove that it is superior to the restricted best linear unbiased estimator in terms of mean squares error and mean squares error matrix, we also give the choice of parameters matrix K.

第五章给出了约束线性回归模型中回归系数的条件广义岭估计，讨论了它的优良性，证明了它在均方误差及均方误差矩阵下都优于约束最小二乘估计，并给出了参数矩阵K的选择。

In this paper, we study characterizations of admissible in the general linear model Y, Xβ,ε|ε～(0,σ~2∑. We demonstrate that an admissible linear estimator is as the conditional generalized ridge-type estimation in the no constraint, equality constraint, inequality constraint general linear model. We study the superiority of this conditional generalized ridge-type estimation, and prove that it is superior to the restricted best linear unbiased estimator in terms of mean squares. We also give the choice of the matrix K.

本文主要研究了一般线性模型Y，Xβ，ε|ε～(0，σ~2∑中参数估计的可容许性特征，得到了一般线性模型在无约束，有等式约束及有不等式约束下，可容许线性估计均具有条件广义岭估计的形式的结论，并且讨论了这一条件广义岭估计的优良性，证明了其在均方误差和均方误差矩阵意义下都优于约束最小二乘估计，给出了参数矩阵K的选取方法。

A new algorithm to the maximum likelihood estimator under ordered restrictions is proposed and is covergent quickly by simulation.

在该研究中，我们提出了优比在序约束条件下的最大似然估计算法，模拟显示该算法收敛速度相当快。

However, its much harder to do the similar research under the pitman criterion.

本文正是在Pitman准则下，讨论了最有代表性的统一有偏估计以及约束统一有偏估计的优良性，给出了Pitman意义下各种有偏估计优于传统最小二乘估计的充分条件。

The results showed that at the standard atmospheric pressure, the highest density of bacteria can be obtained under the following conditions: distilled water, pH 7.60 and 50℃.

统计结果显示：在标准大气压下，从研究样品中获得最多细菌数的较优培养条件为：培养基水源为单蒸水；生长pH为7.60；培养温度为50℃。

Firstly, because the triangle constrained matching propagation begins with the initial corresponding triangulations formed by a few seed points in the stereo pairs, this dissertation studies the affects of different numbers and different distributions of seed points on the image matching results through experimental analysis, and proposes a seed point selection strategy for different image texture conditions, an automatic selection algorithm is also designed that gives good distribution quality for a defined number of seed points.

首先，针对匹配传播过程中的种子点选取问题，通过实验分析研究了不同数量与分布的种子点所构成的初始三角网对匹配结果的影响，进而提出了不同影像条件下的种子点选取策略和一种自动提取一定数量、满足一定分布均匀度的种子点自动选取算法；其次，研究了海量数据情况下同名三角网的快速构建、数据组织存储与局部动态更新的方法；在此基础上，本文提出了随机传播、基于三角形拓扑关系的邻近传播和顾及纹理特征的自适应传播等三种传播策略，分别介绍了其详细的实现算法，并通过实验分析对这几种传播策略进行了比较，实验结果证明自适应传播方法在匹配的可靠性上最优。
