摘　　要：首次采用光学多道诊断系统，通过Ｈα线的观测，研究了托卡马克交流运行期间等离子体的时空行为。结果发现：在电流过零处，等离子体未完全熄灭，使得电流转换后不需要第二次击穿。等离子体的时空行为与电流波形有关。The spatial distribution and temporal evolution of plasma of AC operation in the CT 6B Tokamak has been observed through Hα emissions by an optical multichannel diagnostic system for the first time.The results show the plasma density is not completely lost during current reversal,therefore,there were no need for second breakdown after the current reversal.The spatial and temporal evolution of plasma is dependent on the current wave forms.
