由于四方晶体结构存在各项异性,声速在其中传播时候存在明显的各向异性。基于应力-应变方法,给出了一套计算四方晶体弹性常数的应变方案;更为重要的,从其六个独立的弹性常数出发,可以定量确定声速的各向异性。

Due to the structure anisotropy existed in the tetragonal crystal,the acoustic property also exhibits obvious anisotro-py when sound spreads in tetragonal solids.Based on the stress-strain method,we propose a series of strains that can be em-ployed to calculate the elastic constants of tetragonal crystals.More importantly,it is realistic and feasible to determine quanti-tatively the anisotropy of sound velocity ...
