In the real life, have some to grow similarity since new problem and the old problem are general, unknown object and the known number object get in touch with always mutually, be on basis observing carefully in new problem , overwear knowledge , come to handle the new problem old experience, this thought is that process it is have purpose's , effective conversion contradiction, to solve a problem ultimately change solving problems that process , the mathematics inscribe one kind , is to change from saying , solving problems on this significance melt return to

中文摘要：在实际生活中，由于新老问题总有某种相似之处，未知的事物与已知的事物总是相互联系的，即在新问题仔细观察的基础上，用旧知识、旧经验来处理新问题，这种思维是一种转化过程，数学题的解题过程就是有目的的、有效的转化矛盾，最终解决问题，从这个意义上说，解题就是转化。

The algorithm has some problems, such as bias problem, aliasing problem and one problem that affects none-shade part of image and is caused by Gaussian blur. To solve these problems, this paper makes some improvement on the algorithm. Firstly, it uses the Woos average depth principle and PCF algorithm to solving bias problem and aliasing problem; secondly, it designs and implements an effective method to control the range of blur; thirdly, it adapts any size texture to story information. This method for keeping information plays important part on raising realistic graphic; fourthly, it takes use of the technology of programmable graphics hardware and the method of FBO to improve efficiency of algorithm.

然后，将优生成功解题的思维策略编成教案，在正常的教学实践活动中，有意识地对实验组学生进行有机化学问题解决思维策略训练，以了解学生有机化学解题思维活动特征，促进学生有机化学问题解决能力的迅速提高。实验以株洲六○一中学高三年级理科两个班的学生为被试，以自编《高中有机化学问题解决能力检验的前测和后测试题》和自编《高中生有机化学解题思维策略训练教程》各1套等为材料，通过6周的教学训练，收集训练前、后有机化学测试成绩等数据，采用SPSS10.0进行统计分析，得出如下研究结论： 1、对高三年级学生进行有机化学解题思维策略训练能有效地提高其有机化学解题能力。

Thirdly, we examine a job scheduling problem, in which jobs could be processed by multiple in-line steppers. This problem includes two decisions: job assignment and job sequencing. Through developing a new and concise representation scheme for modeling the two decisions, we solve the multiple-machine scheduling problem by various meta-heuristic algorithms. The preceding single-machine scheduling problem in fact is a special case of the multiple-machine scheduling problem.

第三部分探讨在多机情境下，求解工件排程问题，在此情境下产生两个决策变数：工件指派给各机台，以及工件在机台内的排序问题；为了解决此问题，本研究透过新的染色体设计，能同时代表此两个决策变数，使得解题空间变小，求得更好的解题品质。

Besides, HIF-1 can quickly induce a lot of expressions and the adjustment of anoxia-induced genes, so as to enhance the hypoxia-induced genetic transcription and increase the expressions, and engender physiological effects, such as adjusting the transcription of EPO genes to increase their production, thereby the red blood cells quantity is enlarged, which strengthens the ability of oxygen transportation and mitigates anoxia; adjusting VEGF genetic transcription to engender more blood capillaries, consequently the transportation and supply of oxygen and substance of energy source are strengthened; adjusting the glycolytic enzyme to enhance glycolysis ability under anoxemia condition and increase energy supply; functioning on HO-1 genes in vascular smooth muscle cells to produce HO-1, which can engender NO and CO as pneumatic signal molecules to activate the guanylate cyclases, thus CGMP level is improved to make the vascular smooth muscles chalasia, to restrain platelet agglutination, so that theblood flow and vascular permeability are increased, and the anoxic tissues obtain ample oxygen supply, etc..

在低氧环境中，HIF-1可以被很快诱导大量表达并介导低氧诱导基因的调控，使低氧诱导基因转录增强，表达产物增多，产生生理效应。
