摘　　要：在HL-2A的实验中,我们采用了一种像素法二维层析成像分析技术对软X射线进行反演成像。该方法可对等离子体截面软X射线分布提供详细及可视化的研究方法。该二维层析反演方法已经在HL-2A上得到了成功应用,重建了杂质注入过程和双锯齿破裂过程。Results of the two-dimensional reconstructed distribution of soft X-ray emission on the HL-2A tokamak are presented. Improvement of soft X-ray cameras and development of tomography software have been given in details with visual studies of soft X-ray emission on the HL-2A tokamak. Several algorithms are employed to get detailed images while keeping least guiding assumptions. Recently a 2D peeling away algorithm for tomography reconstruction of the HL-2A soft X-ray data is applied successfully. It helps the research of impurity injection and double sawtooth crash.
