| 中文摘要: |
| 本文提出了一种水平成层介质中弹性波粘弹性波计算的新方法，分别研究了线源和点源作用情况。该方法适用于各种粘弹性模型，数值计算简单，可模拟任意震源及所产生的各种体波、面波，数值结果表明具有很高的计算精度和计算效率。 |
| 英文摘要: |
| A new method to calculate elastic and viscoelastic wave in stratified media is presented in thispaper,and problems of line sources and point sources are discussed here.The method presentedcan apply to all kinds of viscoelastic model, by which arbitray sources and various types of bodywave and surface wave excited by these can be simulated. The numerical procedure of this methodis very simple and the results show that it is of high computation precision and efficiency. |
