4) head-to-tape contact
头带接触
5) phase contact
相接触带
6) vertical sheet
垂直接触带
1.
Taking the potential caused by vertical sheet in the point source current field domain for example,based on programming with FORTRAN,the result is analyzed by the use of the above-mention two methods respectively,and comparison on accuracy based on the result is made to determine precision and availability of the analysis solution.
作为地球物理计算中常用的两种方法,数值解和解析解各有特点,以求节点电源场中垂直接触带地表节点电位为例,基于FORTRAN语言编写程序,分别用解析计算法和数值计算法进行求解,并对求解结果进行精度比较,以确定解析计算法的准确性和可用性,从而确定了一种效率更高的计算方法。

矿物接触带电
contact electrification of mineral
kuongwuJ旧ehu doid一an矿物接触带电(eontaet eleetrifieation ofmineral)电选作业中矿粒直接接触带高压电的电极而带电的方法。由于带电极的电压高，矿粒电位低，故导体矿物立即获得与电极符号相同的电荷，随即受到带电极的排斥而离开电极。柞导体矿物的矿粒则不能带电，只能极化而粘附在电极上。 (刘永之)
