With the rapid development of eletronics and computer technology , no invasion blood pressure instrument based on oscillometric method begin to come out 随着电子与计算机技术的飞速发展,基于测振法的无创血压仪相继问世。
The modal parameters are the basic data for structure dynamic analysis and vibration control . the methods of modal parameters identification can be cataloged into phase resonance testing ( normal - mode force appropriation ) and phase separation approaches 目前,识别模态参数的方法可分为相位共振法(适调多点激振法)和相位分离法两种[ 1 ] 。
