雨滴大小和下落位置对测量雨滴半径精度的影响

根据几何时线光学理论研究了光学测雨实验系统中雨滴半径、下落位置对雨滴半径的测量值精度的影响。分析表明：同一半径的雨滴，离接收器越近，接收器接收到的散射光越多，光闪烁信号峰值越小；不同半径的雨滴，产生的有效消光系数不同，导致雨滴半径测量误差较大，通过雨滴进行分类处理，该项误差减少到０．０４ｍｍ以下。     

流褶层及韧变带研究

流褶层与韧变带是地壳拉伸变形，顺层固态流变作用下的产物。流褶层是以原始层理为变形面或再经递进变形的褶皱变形岩层或岩石共生组合层位。韧变带具明显的层控性，受岩石成分和应变程度控制，不同环境和不同成分岩石的韧变带具有相异的组合型式和变形机制，井具有一定的递变规律。流褶层和韧变带可分属不同层位，但流褶层可实现向韧变带的转化。

Experimental Research on Microscopic Indicators of Temperature＇ s Returning-to-Zero in Deformation of Calcite and Discussions of Correlation Problem

In order to determine the degree of returning-to-zero of temperatures of deformed calcite, a series of rock-breaking experiments were designed to test calcite-rich limestone samples under fixed confining pressures and different temperatures. The consolidated deformed samples in their initial state were observed under a microscope and the microscopic indicators in different zero-returning states were put forward, thus providing a microscopic foundation for evaluation of reliability of dating values of deformation in calcite. At last, the correction of dating values of deformation for samples whose temperature has not yet returned to zero is discussed.
