Calculus can be called a subject about limitation,and infiniteness is a special kind of function for which the limitation is zero.This paper first introduces effect of the appearance of infiniteness in history.Infinitesimal quantity is a great tool to solve the limitation questions.And we summarize the application of Infinitesimal quantity in solving various limination questions.Since the beginners always make this or that kind of mistakes in using the substitute of Infinitesimal quantity,we furthermore analyaze the root of these mistakes.And we also extend the Infinitesimal quantity to power-exponential function,variable upper limit integral,and limit function of two variables. 本人手工正确翻译如下：
