声速法 meaning in Chinese
sound velocity method
Examples
- The sonic velocity orientation structures and mechanical properties of new material of bulked silk and memory silk , ect . by measuring the sonic velicity orientation and modulus are studies
采用声速法测定纤维的取向因子和声速模量，研究了各种真丝新材料的取向态结构及其力学性能。 - For example , the quenching and quenching plus low tempered structure of 38crmoal are hard to be differentiated by velocity method and the principal frequency technique . it will be better if they are differentiated by the method of relative attenuation coefficient
38crmoal钢的淬火与淬火+低温回火组织，用声速法和主频率比较法都难以区分，最好的方法是比较功率谱谱峰特征(幅度、数量、分布) 。
