摘要
对被积函数除有限个点外,具有二阶、三阶、四阶连续导数的情况,使用分部积分法给出定积分抛物线法近似计算的误差估计.在具有四阶导数的情况下与文献[1]的结论相同,但条件稍弱.
This paper gives errors estimate in parabolic approximate calculation of definite integral. We use integration by parts and suppose integral function provided with nth continuous derivative except tin＇re point set （ n = 2,3,4）. Where the condition of n = 4 is weaker than [ 1 ] and same result.
