摘要
针对含两个无穷小的极限问题,采用多元函数泰勒展开的方法,给出了可以同时分别等价替换的一般性条件,推广了等价无穷小可以替换的范围.
According to the limit of two infinitesimal problem,the method of multivariate function Taylor expansion was adopted,the general condition of equivalent substitution was given,and the equivalent infinitesimal substitution area was generalized.
