摘　　要：托卡马克是当前世界实现受控核聚变的主要途径．在ＨＬ－１托卡马克（中国环流器一号）上用偏压电极实现了从低约束模（Ｌ模）到高约束模（Ｈ模）的转换，研究了外加径向电场对这种转换的作用及等离子体性质的变化．此工作是我国核聚变研究的新进展和重要成果．该文简要地介绍了此项研究工作的物理内容和意义。The H mode has been induced by the biased electrode on the HL-1 Tokamak. The L-H transition takes place and related phenomena in the plasma are observed. The time scale of the reduction of the edge parameters is much faster than the time scale of the changes of the global parameters, indicating that the L-H transition starts at the plasma edge and gradually develops into the plasma center, To access the H mode the electrode current plays an important role. A theory of the H mode induced by the biased eletrode has been developed which agrees fairly well with the experimental results.
