rootmeansquare displacement

用法例句

In order to examine how nonlinear hysteretic restoring force of the devices of base isolation and shock absorption is able to influence the response of root-mean-square displacements for two-degree-of-freedom (2-DOF) primary-secondary systems,hysteretic restoring force of the two devices are expressed by a nonlinear differential equation with several parameters as variables.
