ＨＬ－１托卡马克从１９８４年建成至１９９２年底共运行了８年，获得了丰硕的物理实验和工程技术的科研成果，真空室运行状态总的来说是良好的。本文描述真空室在高功率放电实验运行了８年后的主密封结构状态、孔栏烧蚀、真空室壁状态及其污染概况等。
The HL-1 tokamak has been in operation for eight years since it was completed in 1984 and has been in operation for eight years since the end of 1992. It has achieved fruitful research results in physical experiments and engineering. The operating conditions of the vacuum chamber are generally good. This article describes the state of the main seal structure of the vacuum chamber after 8 years of high-power discharge test run, hole column ablation, vacuum chamber wall condition and its pollution profile.
