In chapter 2 we propose a linear equality constraint optimization question , the new algorithm is combined with the new conjugate gradient method(HS-DY conjugate gradient method)and Rosen"s gradient projection method , and has proven it"s convergence under the Wolfe line search.In chapter 3 we have combined a descent algorithm of constraint question with Rosen"s gradient projection, and proposed a linear equality constraint optimization question"s new algorithm, and proposed a combining algorithm about this algorithm, then we have proven their convergence under the Wolfe line search, and has performed the numerical experimentation.

在第三章中我们将无约束问题的一类下降算法与Rosen投影梯度法相结合，将其推广到线性等式约束最优化问题，提出了线性等式约束最优化问题的一类投影下降算法，并提出了基于这类算法的混合算法，在Wolfe线搜索下证明了这两类算法的收敛性，并通过数值试验验证了算法的有效性。

Results:Part1: Mean serum EPO concentration of CRF patients showed significant lower than that of control. After transplantation, renal function recovered quickly while Hb level increased steadily in 37 patients with immediate graft function. Their EPO concentration increased significantly and double peaks of EPO level were obtained at day 4 and week 4. 4 cases in IGF suffered from post-transplant erythrocytosis. But their EPO concentration did not reach statistical significance. 5 cases developed delayed graft function, without EPO double peaks and their EPO concentrations showed signiffcant lower than that of IGF.

结果：第一部分：尿毒症病人血清EPO浓度明显低于正常对照值。37例立即肾功能恢复者，SCr迅速下降，Hb上升，其血清EPO浓度在术后第4d形成第一个高峰，与术前和正常对照比较均有显著差异，其后开始下降，在术后4w时再次升高形成第二个高峰。4例IGF患者在术后16w左右发展为PTE，其EPO浓度值略增高，但与IGF组患者EPO水平无统计学差异；5例DGF患者术后无典型的双峰特点，EPO水平明显低于同时期IGF组，直到肾功能恢复后才逐渐升高。

The source of the Tugela River (Zulu for 'sudden') is at Mont-Aux-Sources several kilometers from the escarpment from which the falls drop.

But subjects of SD had an inclination to make extreme estimation. 4. The region affected by SD expan

因 此，SD后认知功能下降同额叶功能下降有关。

In this paper, we construct the differential equation to solve the unconstrained optimization problem. Such methods solving the ill-conditioned problems are very effective. It indicates that the asymptotically stable region of explicit the Euler method to solve the differential equation equals to the descent region of the gradient method to solve the original unconstrained optimization problem.

我们发现，在用Euler方法求解二次优化问题的等价动力系统的方程时，由方法的步长确定的稳定区域对应于这些方法所得到的迭代公式的步长满足单调下降算法的条件确定的单调下降区域，因此我们可以利用这个性质构造解无约束优化问题的数值方法而不采用标准的常微分方程的数值求解公式。

The latest chemical product prices fell, demand has not really visible downstream, the short-term rise in oil prices in the channel, in which phase fluctuations, we continue to be optimistic about with anti-cyclical businesses and new materials, anti-cyclical embodies New Chemical Materials decrease in prices of raw materials is less than the decrease in prices of raw materials at the same time, the cost shift ability, to maintain price stability; civil explosive materials companies fell as a result, prices, countries can enjoy the benefits of; domestic urea production capacity excess of export disruption, high product costs, industry consolidation is inevitable, so concerned about the urea industry with technical advantages and cost advantages of urea enterprises: China Shandong Hengsheng; Although the overall situation of excess nitrogen, but because of the regional characteristics of the domestic fertilizer domestic part of the region will be in a high urea prices, the relevant listed companies will benefit from, such as the Liao Tung Chemical; compound assets as light industry, with the weak cyclical characteristics, the stability of industry profitability, industry leaders concerned about the compound: para Tian shares ; potash by the international market, short-term decline of domestic potash fertilizer prices would have difficulty, Salt Lake Potash in 2009 will be guaranteed a profit, Salt Lake Potash concern.

最新化工产品价格出现下跌，可见下游需求并未真正起来，短期石油价格处在上升通道，在这种上下波动阶段，我们继续看好具有抗周期性的新材料企业，抗周期性体现了化工新材料的产品价格下降幅度小于原料的下降幅度，在原料价格上涨同时，成本转嫁能力较强，价格维持稳定；民爆企业由于原料下跌，价格上涨，可以享受国家指导价的益处；由于国内尿素产能过剩，出口受阻，产品成本居高不下，行业整合在所难免，因而关注尿素行业内具有技术优势和成本优势的尿素企业：华鲁恒升；虽然氮肥全局过剩，但由于国内化肥的区域性特征，国内部分区域尿素价格将处于高位，相关上市公司将因此受益，如辽通化工；复混肥作为轻资产行业，具有弱周期性特点，行业盈利稳定，关注复混肥行业龙头：芭田股份；钾肥受制于国际市场，短期内国内钾肥价格恐难下跌，09年盐湖钾肥盈利将会有保证，关注盐湖钾肥。

There are distinct drops in the total scores.Except the fear factor of group B.

两组总分、阳性项目数及各项因子分明显下降( P 。0 1 )。A组总分、阳性项目数及各项因子分与 B组相比较下降明显( P 。0 5或 0 。0 1 )。

The declination of baroreceptor reflex function is one of the important factor causing orthostatic intolerance after space flight.

压力感受器反射功能下降是引起飞行后航天员立位耐力下降的重要起因之一。

From another point of view, Golden Eagle's shares rise and fall of profit and loss represents the entire textile machinery rise and fall of the wind vane.

从另一个角度来看，金鹰的股票上升，对盈利和亏损下降代表整个纺织机械上升和下降的风向标。

On the basis of two criteria of stomatal limitation of photosynthesis suggested by Farquhar and Sharkey,the re-dominant limiting factor of photosynthesis is stomatal conductance of stomatal limitation in the forenoon,but the midday depression of photosynthesis at noon and the decrease of photosynthesis in the afternoon are the results of low carboxylation efficiency of the mesophyll leaf.

根据Farquhar和Sharkey的观点，造成净光合速率下降的原因既有气孔限制又有非气孔限制因素，上午净光合速率下降的主要是由气孔限制因素造成的，午间和下午光合速率的降低则主要归因于叶肉细胞羧化效率的降低。
