The condition that the 0^0 type limit limf(x)^g(x) = limf1(x)g1(x) are given, in which f(x), g(x), f1(x), g1 (x) are infinitely small and f(x)-f1(x) , g(x) - g1 (x), f(x)〉0,f1(x)〉0, g1(x) ≠0. Our condition is weaker than the condition in the paper referred. As an application, several examples are given at the end of the paper.%给出求0^0型极限limf(x)^g(x)用limf1(z)g1(x)代换的条件,其中,(x),g(x),f1(x),g1(x)均为无穷小,且f(x)~f1(x),g(x)~g1(x),f(x)〉0,f1(x)〉0,g1(x)≠0.它是对已有文献所给条件的弱化.实例展示弱化条件之应用.
