摘要
托卡马克等离子体中的杂质会影响托卡马克的放电品质及等离子体特性。许多理论和实验对杂质的产生和输运做了深入详细的研究。等离子体电流起始阶段,由于约束性能不好,会引起大量的杂质产生,辐射损失增大是杂质增加引起的直接后果。杂质辐射是等离子体辐射的主要组成部分之一,等离子体线辐射功率～Z<sub>eff</sub><sup>6</sup>,复合辐射功率～Z<sub>eff</sub><sup>4</sup>。
The characteristics of radiation and impurities in the plasma current increasing phase have been studied in detail. It is found that about 80% of the Ohmic power is lost by radiation during this phase, and the intensity of the radiation is closely related to the MHD instabilities. The impurity radiation increases with gas-puffing due to density increase.
