The projection gradient method will be a possible way to solve the problem that we just get. It has been shown that the projections of the every directions, of which is the boundary point in linear restraint problems, are the possible decent directions, and the projection of negative grads direction is a decent direction. In 1960, Rosen proposed the basic idea of projection gradient methods, and then lots of researchers have been tried to find the convergence of this method. But most of them get the convergence with the condition to amend the convergence itself.

在约束最优化问题的算法中怎样寻找有效的下降方向是构造算法的重要内容，在寻找下降方向方面可行方向法中的投影梯度法有效的解决了下降方向的寻找问题，利用线性约束问题边界点的任意方向在边界上的投影都是可行方向，而负梯度方向的投影就是一个下降方向。60年代初Rosen提出投影梯度法的基本思想，自从Rosen提出该方法以后，对它的收敛性问题不少人进行了研究，但一般都是对算法作出某些修正后才能证明其收敛的，直到最近对Rosen算法本身的收敛性的证明才予以解决。

The total effective rate of clinical effect was 88.1% in treatment group and 52.9% in control group. The clinical therapeutic effect of the treatment group was obviously better than the control group. Both groups had a notable seducement in HOMA-IR, FINS, FPG, 2 h PG, HbA1c, TG and LDL-C with an obviously improvement in ISI after the treatment. Compared with the control group, the treatment group had a significant decrease in TC and CRP with notable difference.

Methods Perfusion weighted imaging was performed in 45 cases of cerebral infarction. The sidetoside ratios of regional cerebral blood flow,regional cerebral blood volume and mean transit time were measured at duty lesion of ischemia. The hypoperfused cerebral areas and the stages of ischemia were defined as follows:compensation stage: rCBF was normal, rCBVwas increased, MTT was prolonged;decompensation stage: rCBF was slightly decreased, rCBV was normal or decreased, MTT was prolonged;preinfarction stage: rCBF and rCBV were decreased,MTT was prolonged.
