The experiment results show that the damping capacity of deformed Martensite first decreases sharply and then keep constant with the increase of frequency at the low strain amplitude;
结果表明，当应变振幅较低时，形变马氏体的阻尼值随频率的增加先急剧下降至一定值后趋于稳定；
Measuring the dynamic strain involves the constant modification of gain, as determined by the signal amplitude. This practice suffers from the complex test and the low accuracy.
在动态应变信号测试中，经常需要根据信号的幅值不断调整放大器的放大倍数，测量电路复杂，精度低。
