dynamic damping meaning in Chinese

动力减震
动力阻尼

Experimental study on dynamic damping ratio of frozen soil under cyclic loading
循环荷载下冻土的动阻尼比试验研究
In this paper , some aspects such as the behavior of pore pressure of unsaturated loess , the dynamic constitutive relationship and the characteristics of the dynamic modulus , dynamic strength and dynamic damping ratio are studied with the dynamic torsional shear test of loess
在以上研究的基础上，本文又通过黄土的动扭剪试验研究了非饱和黄土的孔隙压力特性、动本构关系、动剪切模量特性、动强度特性以及动阻尼比特性。
