出现双解,是解答电学计算题常遇到的现象之一.而得出的双解,往往会出现这样一种特殊情况:从数学角度看都是正确的,而从物理学角度看则不一定都正确.为什么会出现这种情况呢?
The emergence of double solution is one of the phenomena often encountered in the solution to the problem of electrical calculation, and the resulting double solution often appears to be such a special case: from a mathematical point of view are correct, but from a physical point of view is not It must be all right. Why does this happen?
