The limit function of the sequence of continous function is not always continous. It brings about many difficulties in theory and application.
众所周知，连续函数列的极限函数不一定是连续的，这在理论与应用上均造成许多障碍。
It is neither the limit of sequence nor the limit of function, but it is a special limit in which it seems the description of variable and the change process of variable are not clear.
它既不是数列极限，也不是函数极限，而是一段特殊的极限。变量的描述比较模糊，没有清晰的变化过程。
