平均效果 meaning in Chinese

averaged effect

The purpose of this thesis is to investigate the control effect of a semi - active vibration absorber developed for an offshore platform and a vibration control system is also designed . the vibration of the structure is suppressed by installing the new and innovative variable stiffness tuned mass damper ( vstmd ) on the top deck of the platform
计算表明，本控制装置对由随机波浪载荷引起的平台振动有一定的控制效果，对平台甲板加速度响应的控制效果最高可达29 ，其平均效果也在21以上，甲板的位移响应也能得到一定的抑制。
