讨论了剧烈变化电场中的欧姆定律，指出要把在稳恒条件下成立的欧姆定律的形式推广到剧烈变化的电场中应当加以修正，给出了修正后的表达式．
It discusses the Ohm’s law in a drastically changing electric field, and points out that the generalization of the form of Ohm’s law established under steady conditions to a drastically varying electric field should be corrected, and the modified expression is given.
