		     | 摘 要:对Lagrange中值定理“中间点”的渐进性作了定性研究. 通过对f ( x)在( a, b)内低阶可导情形
的研究,发现规律,即把f ( x)在( a, b)内低阶可导可推广至n阶连续可导的情形,进而把正整数n推广到正
实数m ,并得到了更一般性的结论: lim

                | Abstract: This papermakes qualitative research on the p rogressiveness of the intermediate point of Largrange
mean value theorem. By studying the situation of f ( ×) in ( a, b) low order derivableness, we found that f ( x) in
( a, b) low order derivative can be popularized to the situation of n order continuous derivableness, furthermore,
that positive integer n can be popularized to positive real number m, a more generalized conclusion is arrived
