| 摘 要： | 利用具有紧文集的Datubechies正交小波基函数，构造出了一种新的计算一维波动方程的数值方法——小波解法。由于该方法充分利用了Daubechies小波函数良好的局部性质，并且巧妙地运用了Fourier变换，数值试验表明该方法不但精度高，而且计算量小。

| Abstract: | Abstract:Using Daubechies' orthogonal bases of compactly supported wavelets, we give a new numerical method forsolving one-dimentional wave equation. The results have showed that the method has higher accuracy and less computation than any other methods, for it makes full use of good local properties of wavelet function and ingeniously puts Fouriertransform to use. |
