摘　　要：由于真空室的屏蔽作用 ,当极向磁场变化时等离子体区域的磁场不能随极向磁场同时变化 ,环电压的建立存在一增长过程。研究结果表明 ,环电压延迟的时间常数与真空室的等效时间常数一致。在真空室等效时间常数确定的情况下 ,可以确定环电压上升过程。HT- 7U装置环电压建立过程大约需要 2 0The magnetic field in the plasma region can not vary instantly with the poloidal field due to the shielding action of the vacuum vessel. The establishment of the loop voltage is a growing process. The results indicate that the delay time constant of the loop voltage is consistent with the equivalent time constant of the vacuum vessel. The rising phase of the loop voltage can be determined if the equivalent time constant of the vacuum vessel is defined. It takes about 20ms for the loop voltage to reach its steady state value in the HT 7U tokamak.
