The reconstruction problem is ill-posed, so two optimal criterions, the least module and the smoothness criterion base on Tikhonov regularization technique, are introduced into reconstruction algorithm. Many regularization parameters choice strategies are investigated, and the TPA(Two—Parameter Algorithm) strategy which is based on the Morozov discrepancy principles, is implemented in two regularization reconstruction algorithms.Numerical experiment results show that the nonnegative and smoothness constraint condition can overcome the difficulty of iteration semiconvergent, preconditioned technique can improve convergence rate and reconstruction accuracy, smoothness regularization criterion can meliorate ill-posed problem of reconstruction and enhance iteration stability, and the TPA is an effective strategy of regularization parameters choice.

数值试验表明：在共轭梯度法中引入非负约束和光滑约束改善了迭代的&半收敛&性，非负约束保证了解的非负性，光滑约束抑制了重建解的振荡现象，约束算法的重建精度与无约束算法相比大幅度提高；在约束共轭梯度重建算法中引入预优技术，可以加快算法的收敛速度，提高迭代的稳定性和重建精度；引入光滑准则的正则化技术可以有效改善图像重建问题的不适定性，加快迭代的收敛速度，提高迭代的稳定性和图像重建质量，计算正则参数的TPA算法在闪光照相图像重建中是有效的。

In the course system of secondary vocational school, the ideological and political lesson has very important function for the forming of student"s ideological standards and political awarenessAt present there are some questions that can"t be ignored in the teaching ideological and political lesson of secondary vocational school in our country, including: The demand for ideological and political education lacks the level, breaks away from students" inherent demand and social work and becomes a kind of the standard of mechanical dogma; the education content of the ideology and politics lesson pays attention to the political theory knowledge of the thought, is inclined to the thinking with doctrine of knowledge center, the educational course of the ideological and political lesson ignores the forming student"s intact personality, the teaching method of the ideology and politics lesson gets used to rigid inculcates and force to submitting , lacks the effective dredging education and the guiding self-education ,the apparition of the teaching of the ideological and political lesson is unreasonable ,etc Author thinks that the teachers teaching art of the ideological and political lesson is the key to improve the teaching quality of the ideological and political lesson, to accomplish the task of teaching effectively, and to make the good teaching result.

中等专业学校课程体系中，思想政治课对学生思想政治素质的养成，具有举足轻重的作用。目前我国中等专业学校思想政治课教学存在着一些不容忽视的问题，它们包括：思想政治课教育教学的要求缺乏层次，脱离学生的内在需要和社会实际，成为一种刻板的圣贤式的标准；思想政治课的教育内容，关注思想政治理论知识，具有知识中心主义的思维倾向；思想政治课教育教学过程忽视学生完整人格的养成；思想政治课的教育教学方法，习惯于硬性的灌输和压服，缺乏有效的疏导教育和有指导的自我教育；思想政治课的教学评价不合理等。笔者认为要提高中等专业学校思想政治课的教学质量，有效完成教学任务，取得良好教学效果，关键在于思想政治课教师的教学艺术。
