摘要
似稳电流产生的涡旋电场的场线在空间的分布呈两种典型状况:①场线是闭合曲线;②场线是两端伸向无穷远的曲线.但它们均符合涡旋电场场线不中断、是闭合的这一特征.
The lines of eddy electric field that is excited by approach to steady current,have two cases:①each of the line is closed;②two ends of the line extend to infinity.Both of them have the characters that the lines of eddy electric field are continued and closed.
