spectrum velocity meaning in Chinese

频谱速度

4 . based on energy equivalence and power equivalence method separately , the additional damping ratio formula of nonlinear viscous damper is derived and it ' s suggested power equivalence method is more suitable for nonlinear viscous damper . then the transforming equality between actual and spectra velocity of structure is derived , based on which , the additional damping ratio equation is revised
4 、分别采用能量等效方法和功率等效方法，推导了非线性粘滞阻尼器的附加阻尼比公式，指出功率等效法更适合于非线性阻尼器；推导了结构的实际速度和谱速度之间的转换公式，基于该转换公式修正了功率等效方法下的附加阻尼比计算公式。
