静电场中E=0点不能有电场线

以静电场在三维空间分布为前提 ,从电场线的引入、电场线的性质出发 ,通过几个典型电场中场强零点电场线分布的讨论指出 :(1 )电场中场强为零的点没有电场线 ;正对电场中场强零点的电场线不能画出 .(2 )电场线的一般定义及从电场线图归纳的普遍性质符合各种静电场 .

There isn't any Line of Electric Force Where Field Intensity is Zero

Taking the distribution of three dimensional space as a premise in the electrostatic field and starting from the lead-through of a line of electric force and the properties of the line of electric force, through the discussion on several typical distribution of the line of electric force when the field intensity is zero, this article points out: (1) There isn't any line of electric force where field intensity is zero; and cannot draw out the line of electric force when it points directly to the zero point of the field intensity. (2) The general definition of the line of electric force and the universal properties drawn from the chart of the line of electric force conform to any types of electrostatic field.
