First, the grain will be increase at double speed, second, a large scale "structure" builds by collision and coalescence of favorably oriented particles (namely primary phase coalescence), third, primary phase entraps the eutectic structure.

分别研究了浇注温度、拉坯速度、冷却速度等工艺参数对合金组织的影响，结果显示：在本实验条件下，浇注温度以650荀70'℃为宜；拉坯速度以8.4一9.6 cm/min为宜；二次水冷流量控制在1.0一2.0比为宜。综合考虑磁场强度B和冷却速度对非树枝晶组织初生相平均尺寸D和形状因子S影响的数学表达式为：D=A一ns二；。

Adding verapamil in the everted gut sacs, the absorption of 9-nitrocamptothecin was significantly enhanced (P.05), especially more markedly in lower small intestine.

随着维拉帕米浓度的增加，作用逐渐增强，在50μg/ml的维拉帕米作用下，药物90min小肠累积透过量增加了大约2倍。

With a large amount of capital being funnelled into property development,"in general we should be very worried," says Nicholas Lardy, a Chinese banking specialist at the Institute of International Economics in Washington.

Following is the factors ideating with the surface of old concrete in different way ( including brushing surface , chiseling surface , cleaving surface ), adherence agent ( including cement slurry , cement sand slurry , cement slurry with the u expansion agent ), the freeze - thaw circulation times and air - entraining .

主要考察了老混凝土表面不同处理方式(刷毛面，凿毛面，劈裂面)、界面粘结剂类型(水泥净浆，水泥砂浆， u型膨胀剂水泥浆)、冻融循环次数等对新老混凝土粘结面劈拉强度的影响，以及冻融作用下新混凝土加气对粘结面劈拉强度的影响。

On a fresh, sunny morning at the Parco Pineta sports centre, the players involved in Friday night's friendly against Spezia (4-1 with goals from Chiellini, Bojinov, Nedved and Olivera) carried out warm down work - composed of light jogging, stretching and massage - while the rest of the squad took part in a low-key practice match.

空气清新，阳光明媚的周日早晨，参加周五晚对阵Spezia友谊赛(4：1取胜，基耶利尼，博季诺夫，内德维德和奥利维拉各下一城)的队员们在Parco Pineta体育中心开展了氛围热烈的放松活动----由慢跑，身体拉伸和按摩组成----其他队员则参加了一场低调的训练赛。

In order to further understand the st retching effect of polymer-based composites , the Ni/ PVDF films were prepared using a simple physics blending and then st retched at 120℃to improve the elect ronic properties. The

为了进一步研究聚合物基复合材料的拉伸效应，采用简单的物理混合法制备了 Ni/ PVDF复合薄膜并在 120 ℃下进行拉伸改性研究。

As soon as my trousers were nearly pulled below my knees, the boy came back. I took the hot cup from the boy just when the door was about to close and quickly splashed the hot water to Mr. Huang's face and kicked down another guy canoodling me. It was so sudden that they all got confused and disabled to respond instantly. Right when they hesitated in the moment, I quickly got my trousers on and dragged the boy up then scudded off.

就在我的裤子将被拽到膝盖下的时候，孩子把水端了进来，门还没关上，在那孩子站在我旁边把水递给我的时候，我一把将滚烫的茶水泼在门口的黄主任脸上，又一脚把旁边一个正在摸我的大汉踹飞，以迅雷不及掩耳之势拉上裤子，由于事发太突然，他们都被眼前的一幕惊呆了，就在他们迟疑的一刹那，我拉起孩子就向外面飞奔。

The variation of the box girder's stress and strain is discussed according to the results of the different tensioning sequence. And according to the comparison of the simulation results, a reasonable tensioning sequence is given. It will provide reference for the design and construction of similar projects.
