The effect of switching modes on the entrancement,combustion and billet heating process in furnace were analyzed numerically,and the computational results were compared with production records and onsite measurement,which verified the practicability of this CFD system.

结果表明：采用分段同侧换向控制的HTAC加热炉能获得很好的流场和温度场分布，基本满足高质量的钢坯加热需要，但该炉在生产条件下的温度制度存在不合理之处，在今后设计和操作中应进一步优化和改进；全同侧换向控制的火焰布置方式不利于钢坯的均匀、快速加热；而采用交叉换向控制的火焰布置方式可以改善加热炉内的流场和温度分布，更有利于满足钢坯的加热工艺要求。

The fire broke out in the end it is the backyard of last resort, or on the market to determine the error, or out of band operation to consider, perhaps follow-up of the market data can give an answer.

火警发生在最后这是最后的手段，或在市场后院，以确定该错误，或从波段操作考虑，或许后续的市场数据可以回答。

After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.

具体制备工艺为：首先以L-苯丙氨酸为原料采用重氮化方法得到-2-氯-3-苯基丙酸，再经酯化得到-2-氯-3-苯基丙酸乙酯后在乙醇钠催化作用下和丙二酸二乙酯缩合，发生SN2反应，得到相应的三乙酯，然后经水解和脱羧，得到-苄基丁二酸；在实验中乙醇钠要和丙二酸二乙酯充分反应，避免生成肉桂酸乙酯；该过程操作简单，原料便宜，产率较高，总收率可达到26.8%。

And a solution for crowd path navigation based Voronoi diagram is presented. By making use of the ability that the Voronoi diagram partitions the space according to the Euclidean metric, the path planning with collision avoidance is achieved by forbidding agents to move outside their Voronoi regions.

利用Voronoi图对平面按照欧式距离进行划分的特性，并通过将每个虚拟人的Voronoi区域作为其活动范围，使每个虚拟人都限制在自己的区域内活动，从而在人群路径规划中避免了为虚拟人进行碰撞检测的复杂操作。

The Russian square piece is a get-away drama with all proper old 幼, it carry out to be constitute by four pieces of colors of exact square piece, then save in one four chemical elements of the piece set, random creation dissimilarity of calculator seven the square piece of the category type, control it according to the calculator clock in certain time continuously creation, the customer is inside out according to four directions key control of the keyboard, to left, rightwards and get down the operation,.

俄罗斯方块是个老幼皆宜的小游戏，它实现由四块正方形的色块组成，然后存储在一个数组的四个元素中，计算机随机产生不同七种类型的方块，根据计算机时钟控制它在一定的时间不停的产生，用户根据键盘的四个方向键控制翻转、向左、向右和向下操作，（控制键的实现是由键盘的方向键的消息函数实现）。
