amplitude of oscillation meaning in Chinese

摇幅
振荡振幅

This isi series oscillation has following characters : ( 1 ) long term cycle duration , whose duration of most oscillations ranged from 3 0 - 120ms , so we called it slow wave oscillation ; ( 2 ) large amplitude of oscillation , the minimum isi is about 2ms while the maximum is beyond 40ms , which suggested that the firing frequency vary from several tens to hundred hz ; ( 3 ) abrupt turn always occurs during the continuous change in isi , this turn is called inflexion temporarily
该振荡波有下述特征：（ 1 ）振荡周期较长，多数在30 ? 120s范围，故称慢波振荡；（ 2 ）振荡幅度较大，其isi振荡最小值在zms左右，最大值可达40ms ，表明放电频率可在几十到几百k范围内变动；（ 3 ）在isi连续变化过程中往往出现突然转折，暂称其为拐点。
