查询词典 U

The article aims to study the interface shearing force regularity of the steel and concrete composite beams with cold formed steel U section with a new method to build calculation formulas of interface shearing force with symmetrical concentrated loads and uniformly distributed load.

目的 采用一种新方法建立冷弯U型钢与混凝土组合梁的界面剪力计算公式，研究冷弯U型钢与混凝土界面剪力分布规律。

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head. These problems are concerned by the carling factories and do not solved for a long time. The mechanism of the carling forming and spring back is analyzed. The carling forming and spring back processes are simulated by KMAS software. The warp of carling underside is researched by half analytic and half experiment method and the best scheme is found by this method.

针对纵梁冲压成形及卸载后发生的U型截面侧壁的外扩、内缩、扭转以及纵向端头翘曲等问题，首先分析了纵梁的成形及回弹变形机理，利用仿真分析软件KMAS进行了数值模拟并采用半解析、半实验方法研究了纵梁底面翘曲，找出模具结构的最佳方案。

Also, it is derived from theory that the gas-liquid flow in the inverse U tube is stable in all the flow pattern map.

然后从理论上对倒U型管内气液流动进行稳定性分析，得出倒U型管内气液流动在全流型范围内处于稳态。

In terms of luminance performance of BLUs, there shows no much difference between V-cut and U-cut microstructures from simulation results. However, U-cut microstructure outperforms V-cut one in luminance uniformity.

另外在整体BLU辉度并未因入光侧添加微结构而有大幅的变化及差异的前提下，U-cut纵沟微结构的使用效果会比V-cut纵沟微结构来的好，除了在入光测量测点均齐度提升略胜一筹外，其入光侧明暗不均问题亦可处理地更为淡化，以达到光学及品味之最佳化。

Three control factors, involving in the optimization process: the pitch and depth of both V-cut and U-cut, and angle and radius for V-cut and U-cut, respectively, are the same as full factorial experiment method.

后同全因子实验选定入光侧V-cut纵沟微结构三组控制因子及入光侧U-cut纵沟微结构三组控制因子。

The U.S. and Europe will have 'U-shaped' or 'W-shaped' recoveries, economists argued, meaning they believe the upturn since late 2009 will fizzle out later this year.

经济学家认为，美国和欧洲将经历U型或W型复苏，这意味着他们相信2009年年末开始的反弹势头将在今年某个时候结束。

We are also pleased to report continual progress in our U-Can program, which provide after-school tutoring all stoppages in the preparation for the gaokao, which is Chinese college entrance examination.

我们还很高兴地看到了我们U-CAN项目不断取得的进步，U-CAN项目是为所有为重新高考而准备的人提供课后辅导，也就是中国的普通高等学校招生全国统一考试。

While U denotes an Up Face quarter turn of 90 degrees clockwise, U2 denotes a 180 degrees turn and U' denotes a quarter turn of 90 degrees counter-clockwise.

而U2的意思是把'上'面顺时针旋转180度。U'的意思是把'上'面逆时针旋转90度。

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。

To those waiting with bated breath for that favourite media catchphrase, the U-turn, I have only one thing to say: You turn if you want to.

对等待者与媒体喜爱的醒目政治宣传标语：U形转弯，我只说：如果您要U形转弯，您转动。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
