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
該振蕩波有下述特徵: ( 1 )振蕩周期較長,多數在30 ? 120s范圍,故稱慢波振蕩; ( 2 )振蕩幅度較大,其isi振蕩最小值在zms左右,最大值可達40ms ,表明放電頻率可在幾十到幾百k范圍內變動; ( 3 )在isi連續變化過程中往往出現突然轉折,暫稱其為拐點。It have been proved that the tip [ ca2 + ] i and the amount of tip f - actin oscillates periodically accompany the oscillatory growth of pollen tubes
