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.

Wang Zhong serves as the main participator that plans at that time, mention at the outset deploy expresses when the original intention of this strategy:"As a result of 2004 when IT " in the winter " just go, the urban market that we analyse China is opposite for degree of saturation is taller, but degree of saturation of 56 class market is lower, market space is very large, industry of as it happens has an opportunity at that time is AMD drop product value substantially, rolled out the product of the introductory class of low end, so we develop such rising market with respect to organic meeting, have a faster growth space in order to allow the business that future associates, actually these rural markets still are in the bud phase that just starts at that time, we have a product to be able to rise prize of this share market, have so such " oneiromancy plans " consideration."
王忠作为当时计划的主要参与者,提到当初部署这项战略的初衷时表示:"由于2004年的时候IT"冬天"刚刚过去,我们分析中国的城市市场相对来说饱和度比较高,但是五六级市场饱和度比较低,市场空间非常大,当时正好业界有一个机会就是AMD把产品价格大幅度下降,推出了低端的入门级的产品,所以我们就有机会开拓这样的新兴市场,以让未来联想的业务有一个更快速的增长空间,实际上当时这些农村市场还是处于刚刚启动的萌发阶段,我们有产品就可以把这部分市场撬动起来,所以就有这样的"圆梦计划"的考虑。"

Compared with that of 3Cr13 alloy, the oxidation resistance of the composites containing 5 vol.%TiC particle was improved greatly at 850℃, but the improvement was relatively limited at 950℃. But the oxidation resistance of 1Cr18Ni9 composites containing 5 vol.% TiC particle was obviously improved at 950℃, and at 850℃ the improvement is not large. The TiC particle can improve the oxidation resistance mainly was by developing the oxidation selectiveness of the Cr element as to change the phase constitution of the oxidation film, to alleviate the production of the stress in the oxidation film and to improve the cohesive force of the oxidation film or matrix interface and the chemical combination of the oxidation film.
