在最新书刊中,对地震脉冲在粘滞弹性介质中传播时,其产生、位移、速度函数和加速度函数雷克都给出了积分表达式。这些函数的解是一维斯托克思波动方程。雷克把它们作为振荡函数的无穹积分。本文,将这些无穹积分变换成被积函数的有限积分。它通常带有单一符号;这些新的积分容易用简单数值积分(例如,辛普森法则)来估算,并且容易得到高精度的估算值。本文给出了某些数值结果,并将它们与雷克所制的表作了比较。
In the latest publications, when the seismic pulse propagates in a viscous elastic medium, the integral expression is given for its generation, displacement, velocity function and acceleration function. The solution to these functions is a one-dimensional Stokes Fluctuation equation. Rick treats them as voidless integrals of the oscillation function. In this paper, we transform these non-vault points into finite integrals of integrand. It usually has a single sign; these new points are easy to evaluate with simple numerical integration (eg Simpson’s Law) and easy to get high-precision estimates. Some numerical results are given in this paper, and they are compared with those made by Rick.
