通过将简化的碰撞辐射模型与自限烧蚀模型相结合，研究了托卡马克放电中h α线发射率与氢球烧蚀率之间的关系。在正常的欧姆加热放电中，除了最大烧蚀率相对于最大排放率有轻微延迟外，燃料沉积曲线可以由h α线发射曲线精确地再现。
By incorporating a simplified collisional-radiative model into a self-limited ablation model, the correlation between the emission rate of the Hα-line and the ablation rate of a hydrogen pellet in tokamak discharges is studied. In normal Ohmically heated discharges, the fuel deposition profile is reproduced accurately by the Hα-line emission profile, except for a slight delay of the maximum ablation rate with respect to the maximum emission rate.
