mechanical mass meaning in Chinese

力学质量

There are many things can be used as electrorheological ( er ) materials , such as polymer semiconductor er materials , inorganic nonmetal materials et al . the advantage of polymer semiconductor er materials attributes to theirs high mechanical mass , lower density and fine hydrophobic properties , at the same time , theirs conductivity can be adjusted by doping and after - treatment , but theirs poor thermo - stability confines theirs extensive use
有许多种材料都可以用作电流变材料，例如，聚合物半导体材料，无机非金属材料等，聚合物半导体er材料的优点在于有较高的力学值、较小的密度、优良的疏水性，可以通过控制掺杂量和后处理程度有效控制电导的大小。
