摘　　要：从数学方程角度研究似平行场激励和平行场激励下的独立投影角度数,结合矢量分析得到这两种激励方式的独立投影角度数一致的结论.运用Landweber算法进行图像重建的仿真实验,结果也证明了这个结论.A further step based on mathematical equations is carried out to calculate the number of independent projections under the parallel-field exciting mode and the quasi-parallel-field exciting mode respectively. It is concluded that the number of independent projections under the two modes are the same while the method of vector analysis is employed. Afterwards, the results of simulation experiment of image reconstruction based on the Landweber Algorithm also shows that the independent projections of the two exciting modes are the same.
