摘要
在时间－空间域中将二维波动方程化为常微分方程组，利用快速收敛级数逼近函数ｅ￣ｙ，由此导出顺时间递推公式并得到精确的正演模拟时间剖面。
The 2-dimentional wave equation was replaced by the couple of first order in time system of equations in time-space domain. Function ey was adopted to be approximated by an exponential converging series. The formula was derived, by which the wave field was continued in the direction of time. The accurate time section of forward modelling could be thus obtained.
