The maj or obj ect of this paper is the medium.small size concrete dams that have been used for many years.They have the characteristic that the alteration of water height of reservoirs is unobvious and the dams, displacements are affected mainly by temperature.With a case,the method of stepwise regression is used to analyze the vertical displacement prototyDe observed data.Then regression equation is established,the relation of dam,s displacement with hydraulic pressure、temperature、time effect is analyzed and the displacement change rule is obtained,the dam'S displacement onlv dependent to temperature is received.According to the theory of Finite Elements Method,the quasi-stationary temperature field formula and temperature stress formula are deduced.The QTP program and TFEM3D program are written with FORTRAN.The same case is calculated through QTP program to solve the quasi-stationary temperature and through TFEM3 D program to solve the dam'S displacement and find tlle dam,s deformation rule.This rule is accordant with the regression,S resuIt.

本文主要针对运行期间库水位变化很小、坝体的位移主要受温度变化影响的中小型混凝土坝，结合工程实例，采用逐步回归的方法对垂直位移原型观测资料进行分析，建立回归方程，分析坝体位移与水压、温度、时效之间的关系以及位移变化规律，分析结果坝体位移只与温度有关，而基本上不受库水位变化和时效的影响；根据有限元原理推求了混凝土坝准稳定温度场公式和温度应力公式，利用FORTRAN语言编制出QTP准稳定温度场程序和TFEM3D位移场程序，对大坝的温度场和位移场进行计算，求出坝体结点的变温值和坝体结点位移值以及单元应力分量，分析得到大坝的变形规律与实测资料以及回归统计变形规律一致，说明对坝体准稳定温度场的研究是正确的。

In chapter 1, regression models with censored data, LSE for censored regression models and LAD estimation for models with fixed censoring point are introduced. Then, we state our main results for LAD estimator of nonlinear regression models with randomly censored data, including consistency, boundedness in probability and asymptotic normality. The proofs of our main theorems are given in detail. In chapter 2, we state the main difficulty of obtaining numerical solution for censored LAD estimation, and recall the history of studies on this problem including some anterior algorithms.

4Some job stressors can predict job burnout, stresses form ecomocial-socail treatment, workload and school management entered emotional exhaustion regression equation, stresses form student factors entered depersonalization regression equation, stresses from workload and examination entered reduced personal accomplishment regression equation. It is clearly that stresses from ecomocial-socail treatment and school management have positive influence to turnover intention; also emotional exhaustion and reduced personal accomplishment have positive influence to turnover intention.
