摘　　要：选用新的基函数,结合Lagrange插值法,用小波配点法求解了热传导方程,得到了较高精度的计算结果,说明了该方法对一般的线性偏微分方程都是可行的.The paper describe a kind of wavelet collocation method for the numerical solution of partial differential equations. For such a method, this paper proposes a new basis functions to solute the heat conduct equation. This method gains a good accuracy by using Lagrange polynomials to define the function values of the external points to the interval. This method is feasible to all linear partial differential equations.
