摘　　要：能量约束时间是衡量环流器等离子体约束性能的重要参数。分析表明,在加偏压由L模过渡到类H模的过程中,如果等离子体的辐射损失功率与总损失功率之比显著变化,则扣除辐射损失的能量约束时间的增量是一种更好的衡量约束得到改善的尺度。在这种考虑之下,我们讨论HL-1等离子体偏压电极L模一类H模过渡时的能量约束及电子热传导特性。Energy confinement time is an important parameter characterizing the confinement property of a tokamak plasma. In this paper, it is shown that the increment of the plasma confinement time without consideration of radiation losses is a good scale for evaluating the plasma confinement improvement during the L-H like transition induced by electrode bias in tokamaks, if the ratio of the radiation power to the total loss power in the transition changes evidently. According to this consideration, we discussed the energy confinemet and electron thermal conductivity in L-H like transition induced by electrode bias in the HL-1 tokamak.
