摘　　要：基于Daubechies小波基,用有限元方法求偏微分方程数值解的一个重要问题就是:如何确定相应的关联系数-Daubechies小波的尺度函数、小波函数或者其导数乘积的积分.给出关联系数的定义以及计算关联系数的算法.Based on Daubechies＇ wavelet basis, the typical problem that arises when using finite element method to solve PDEs, is how to calculate the connection coefficients - an integral of products of scaling functions of Daubechies＂ wavelet, wavelet functions or derivative operators associated with these. The definition of connection coefficients is proposed, and the algorithms for computing them are presented.
