This paper will assume that there are effective stock market and effective executive market, and the basic hypothesises in Black-Scholes Stock Options Pricing Model are correct. We will discuss the optimal repricing scheme under three situations, one is that the board of the company considers repricing when the price declines straightly ; the second is at the beginning of stock life,the board promises to reprice under some conditions at a certain coming time; the third is when some condition happens at an uncertain coming time, the board promises to reprice the ESO.

All those whom God has predestinated to life, and those only, he is pleased, in his appointed and accepted time, effectually to call, Ro 8:30 11:7 Eph 1:10,11 by his word and Spirit, 2Th 2:13,14 2Co 3:3,6 out of that state of sin and death in which they are by nature, to grace and salvation by Jesus Christ; Ro 8:2 Eph 2:1-5 2Ti 1:9,10 enlightening their minds spiritually and savingly to understand the things of God; Ac 26:18 1Co 2:10,12 Eph 1:17,18 taking away their heart of stone, and giving to them an heart of flesh; Eze 36:26 renewing their wills, and by his almighty power determining them to that which is good; Eze 11:19 Php 2:13 De 30:6 Eze 36:27 and effectually drawing them to Jesus Christ; Eph 1:19 Joh 6:44,45 yet so as they come most freely, being made willing by his grace. So 1:4 Ps 110:3 Joh 6:37 Ro 6:16-18 2 This effectual call is of God's free and special grace alone, not from any thing at all foreseen in man; 2Ti 1:9 Tit 3:4,5 Eph 2:4,5,8,9 Ro 9:11 who is altogether passive in it, until, being made alive and renewed by the Holy Spirit, 1Co 2:14 Ro 8:7 Eph 2:5 he is enabled by it to answer this call, and to embrace the grace offered and conveyed in it.

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。
