【摘要】 地震波传播的数值模拟中,在有限区域建立吸收边界条件是一个很重要的问题。在不同类型的吸收边界条件中,比较经典地是Clayton和Engquist提出得Clayton-Engquist吸收边界条件,透射边界条件(MTF)是通过直接模拟各种单向波动的共同运动学特征来建立的一种边界条件,算法简单容易。重点讨论了MTF边界条件并通过数值计算与被传统应用的CE吸收边界条件作比较。更多还原

【Abstract】 In the numerical simulation of the wave equation,develop an Absorbing boundary condition in the finite domain is a very important problem.In different kinds of Absorbing boundary conditions,a classical one is Clayton-Engquist(CE)conditions which developed by Clayton&Engquist 1977.Through direct simulation of a variety of one-way fluctuations in the common kinematical features to set up a series of boundary conditions,that are transmitting boundary conditions(MTF).Algorithm is simple and easily calculated.The MTF condition is focused on and by numerical calculation to compare with CE Absorbing boundary conditions.更多还原
