We make the following assumption for When 2 is positive definite matrix, different estimators about matrix of regression coefficients and inefficiency of Least squares estimate have been discussed in many documents. Considered 2 is nonnegative definite matrix, this thesis derives Best linear unbiased Estimate of parameter matrix B and estimable parameter function KBL under the meaning of matrix nonnegative definite and the property of maximum probability of BLUE is investigated.

当∑＞0时，众多文献讨论了回归系数阵的各种估计及LSE的有效性，本文考虑了当∑≥0的情形，给出了回归系数阵B及其可估参数函数KBL的在矩阵非负定意义下的最优估计，研究了它的一个最大概率性质，并且讨论了最小二乘估计成为最佳线性无偏估计的充分必要条件，在此基础上给出了均值矩阵的最小二乘估计与BLUE的偏差估计，定义了LSE相对于BLUE的一个相对效率，并给出了它的界。

Apart from body color of puparial cuticle, there were microstructure differences which were found out by scanning electron microscopy. SEM had denser, more packed structure of the puparial exuviae than that of SEW.

扫描电镜分析结果表明，相对于SEW，SEM的蛹表皮结构更加的致密，表明黑化除了引起蛹的体色发生变异外，还引起蛹表皮结构发生了细微的差异。

In the case of Filch , it may be the male counterpart of "Madam" to refer to an unmarried staff person who is not a teacher.

It has been expounded and verified that AY can only be a fruitage of the process accumulation of the difference in physical elapsed-time caused by the different intrinsic-real velocity of physical clocks between the traveler and earth mainly in the two inertial phases,the Lorentz-Filtzgerald Contraction; which denies the SR's Key Gene and reveals:（1）The Absolute Reference System must objective-uniquely exist in the universe, and ①the Lorentz effect of whole universe relative to ARS all are IRPCE,②the time-space of ARS is isotropic and steady-homogeneous.

这是关于物理时空理论问题的第一个最重要的关键性奥秘！它彻底否定了KGS，揭示了"绝对参照系和相对于ARS的Lorentz-Filtzgerald效应客观存在的必然性"，表明狭义相对论是核心灵魂缺失了的片面性理论。
