摘　　要：ＨＴ６Ｍ托卡马克通过边界欧姆加热实现了改善约束的Ｈ模，利用中性粒子测量方法成功地研究了等离子体Ｈ模放电的中性粒子变化．观察到边界欧姆加热Ｈ模放电期间从等离子体逃逸的中性粒子比纯欧姆加热明显减少；约束改善后等离子体中心热区的中性原子密度下降，得到了反映等离子体约束改善的中性粒子特征．The H mode has been achieved on HT 6M Tokamak by edge ohmic heating (EOH) method. The H mode is studied by the neutral particle measurement method. The escape particle flux decreases during H mode. The central neutral atoms density drop, and the central particle confinement time τ p is increased about one times after applying the EOH.
