摘　　要：从成音生理机制看,喉塞尾会加大喉头垂直运动的幅度,幅度大小(喉头垂直运动值)通过EGG原始信号中低频成分的方均根值计算。喉头垂直运动值可表征喉塞尾的生理属性。经计量分析,喉头垂直运动值与调长负相关。初步测算,喉头垂直运动值40.2为江淮官话4方言点(扬州、南京、芜湖、东台)入声喉塞尾脱落的临界参考值。This paper explores the physiological representation of glottal stops in Entering Tone in the Jianghuai Mandarin.According to the physiological mechanism on the formation of glottal stops,a glottal stop would increase the amplitude of the vertical movement of the larynx.In this research,vertical movement value of the larynx(V value)is calculated by the square root value of the low frequency component in the electroglottography(EGG)’s original signal which can measure the physiological representation of the glottal stop.From the statistics of quantitative analysis,it is indicated that there is a negative correlation between V value and the duration of the stop.The preliminary calculation suggests that the V value of 40.2 is the critical reference value of whether glottal stops in Entering Tone are dropped or not in the four dialects of Jianghuai Mandarin(i.e.Yangzhou,Nanjing,Wuhu,and Dongtai).
