| 中文摘要: |
| 将精细积分法应用到了二维的电报方程的数值计算之中。实例计算表明，该方法具有简单、计算精度高、无条件稳定、不需要进行复杂、费时的频域一时域转换及卷积积分，直接时域分析，处理非零初始值容易等优点。与传统的ＦＦＴ法及ＮＩＬＴ法相比，其效率更高，功能更强。 |
| 英文摘要: |
| In this paper , the precise integration method is used to solve the telegraph equations. The results show that this method is simple , accurate and stable. Especially, not using the tedious and complex transform between frequency-domain and time-domain as well as convolution inte- grals , this method perform analysis in time-domain directly and treat the nonzero initial value much easier. Compared with the traditional methods based on the FFT and the NILT , thismethod is more efficient and powerful. |
