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.

This article analyses the application conditions of freezing method, current research status and the problems in this field. It points that it's necessary to study deep freezing temperature field deeply and discusses the factors which influence the freezing wall such as soil's nature, moisture content, geological conditions, etc. It introduces the theory, process of freezing method, the distribution of temperature field of freezing method and key thermotics parameters influencing freezing temperature field. It simplifies the deep freezing temperature field model. Through ANSYS, this article founds the deep freezing temperature field model, and simulates the field on vary heat conductivities. It analyzes the results of ANSYS simulation, gains the theoretical value of thermometric holes which is needed by back-analysis. Using the simulation temperature and actual value, it gets the equivalent heat conductivity.

We will investigate the actuality of stony deserts in Guizhou, and divide their types on the basis of their intensity, covering rate of soil and vegetation and amount of species, and stduy the influence factors of forming different stony desert types in more coercing, and explore the ratio of influence factors in the different stony desert areas and the evolutionary mechanism of different stony desert types. Finally,we will stduy the growing conditions and species of arboreous in different geology, land form,hydrology region for natural lithogenic forest and artificial forest, and the natural conditions for failing in many artificial forest,and the reconstruction mechanism in different stony desert type regions.

It should be a direction type of efficiency that the government assigns mandatorily. Under the condition of market economy, the income gap of having certain degree is rational ,it is effectual too; Of our country the main cruxeses of unfair distribution of social wealths are the unfair income assign terms and assigning process.vlndividual income tax has little effect in changing this, so it is unfit to put too much blame on the individual income tax law about the current situations of unfair distribution of social wealth; To regulate the income distributes is a system, and managing income unfair distribution should be arranged and develop simultaneously more measures too.

在市场经济条件下，有一定程度的收入差距是合理的，也是有效的；我国社会分配不公的主要症结所在是收入分配条件和分配过程不公平，个人所得税对此所能发挥的作用是极其有限的，因此不能将社会分配不公的现状过多地归责于个人所得税法，要求在指导思想和制度上提高公平特别是实质公平的程度；收入分配的调节是一个系统，治理收入分配不公也应当多措并举。
