探讨了通过测量应力晶体中的声学二次谐波产生来确定四阶弹性模量的可行性。结果表明，在静水压力下，二次谐波振幅平方与基波振幅A2/A21之比的预期变化约为20%-30%/GPa，这应该是很容易测量的。
The feasibility of determining the fourth‐order elastic moduli by means of measurements of the acoustic second‐harmonic generation in stressed crystals is explored. It is shown that the changes to be expected under hydrostatic pressure in the ratio of the second‐harmonic amplitude squared to the fundamental amplitude A2/A21 are of the order of 20%–30% per GPa, which should be easily measurable.
