device n. 1.设计,计划;方法,手段。 2.〔pl.〕意志,欲望。 3.谋略,策略,诡计。 4.器具,器械,设备,装置。 5.图案,图样;花样;纹章;标记,商标;(纹章上的)题铭。 a safety device 安全设备。 a pressure device 压力计。 a homing device 自动寻的[导引]装置。 leave sb. to his own devices 让某人自行其是。
The results of test and theoretical calculation indicate that the friction device does not slide under minute earthquake , thus the control effort of f - ved corresponds with ved , and the action of frd is the same as pure brace . when disastrous earthquake occurs , the viscoelastic material reaches its shear limits and the friction device begins to slide , so the control effort of f - ved is the best 试验结果和理论计算结果表明,在多遇地震下摩擦机构不起滑,粘弹性-摩擦阻尼器的减振效果和纯粘弹性阻尼器相当,而摩擦阻尼器的作用相当于纯支撑;在罕遇地震下粘弹性材料达到剪切极限,摩擦机构起滑,故粘弹性-摩擦阻尼器的减振效果最好。
