| 摘 要： | 本文是作者对纤维在电场中的动态过程及规律进行系统分析和实验研究的第一部分.首先讨论了电场在空间的分布,对纤维在进入电场前后的几种带电方式、带电量及其变化规律进行了较详尽的论述;又引入了纤维重力及输送纤维的气流力并加以分析,最后导出纤维在电场中的运动方程组.以实验测试的数据代入方程中的参变量,借助计算机即可求得纤维运动规律的数值解,并由计算机绘制出不同条件下纤维的运动轨迹.所得结果再与以频闪摄影方法得到的结果加以验证,两者是基本一致的.

| Abstract: | This paper is the first part of the research about the dynamic process and pattern of the fibres in the electrostatic field. The paper discusses the distribution of the electric field in space and describes in details the various manners of the electrification of the fibres and the changing pattern before or after its entrance into the field, then introduces gravity of the fibres and the force of air flow trans-porting the fibres, and finally, derives a group of motion equations of the fibres.Replacing the parameters in the equations with the experimental data, the numerical solutions can be got and the motion locus in different enviornment will be drawn by the computer. Comparing the locus with the results of frequently-flash photographs, they are bosically in conformity. |
