The absorbing boundary condition in VTI media at different boundary and corner point is constructed in frequency domain with eigenvalue analysis method and Kelvin-Christoffel equation, and the attenuation boundary is established simultaneously by using the perfectly matched layer (PML) method.
首先给出了VTI介质准P波波动方程,阐述了特征分析方法的基本原理,讨论了边界上的反射系数与入射角和度量准纵、横波各向异性强度因子的关系;然后利用特征分析法结合Kelvin-Christoffel方程,构造了准P波波动方程在不同边界和角点的频率域吸收边界条件,利用最佳匹配层法构造了衰减边界条件;最后利用数值模拟对构造的边界条件进行了验证。
It is pointed out that the necessary condition for obtaining optimum coating in the.
指出在自动送粉式激光熔覆中能够获得最佳熔覆层的必要条件是：熔覆材料颗粒进入激光束后直到其落到基体材料表面之前，必须始终在激光束中。
