容积弹性模数 meaning in Chinese

modulus of elasticity of volume
modulus of volumetric elasticity

First , mathematical model of swaying system is made , which is a basis on later chapters . meanwhile , the system is simulated and designed . the effect of loaded mass , loaded suppleness , general leaking coefficient and cubage elasticity modulus on performance of system is also analyzed
首先，作者建立了横荡控制系统的数学模型，作为以后各章节讨论的基础，同时对系统进行仿真和设计，并研究了系统负载质量、负载刚度、总漏损系数和容积弹性模数对系统性能的影响。
