首次将不可回收的杂质注入欧姆HL-2A等离子体中。钛和铝的杂质被注入具有不同等离子体密度和电流的放电中。定性研究了注入杂质离子向内阶段的对流和扩散过程。结果表明，等离子体中心区域的杂质传输比等离子体外部慢得多，并且在锯齿碰撞期间大大增强。
Non-recycling impurities are injected into ohmic HL-2A plasma for the first time. The impurities of titanium and aluminium are injected in the discharges with varying plasma density and current. The convection and diffusion process of the injected impurity ions during the inward phase are qualitatively investigated. The results show that the transport of impurities is much slower in the central region of the plasma than outside of it and that it is greatly enhanced during sawtooth crashes.
