摘要
将文献［１］中给出的只适用于（ａ，ｂ）区间内某些点的两个命题推广至适于（ａ，ｂ）内任意点，推证出两个新的微分中值定理．从而为利用导数研究函数在（ａ，ｂ）上任意点的性质提供了重要工具．
Two propositions applied to only some points in the interval (a,b) in reference are extended to the two new propositions applied to any point in (a,b).Thus it is an important tool of studing the properties of functions in any point in (a,b) by means of derivative.
