内扭转

The activation energy of B ring elementary reaction is between 16～20kJ/mol.

从IRC结果以及对过渡态结构的电子密度拓扑学分析结果可以确定，羟基自由基在反应过程之中抽取了黄酮类化合物A环上未参与分子内氢键结构的酚羟基上的氢原子形成水分子及稳定性更高的半醌式大环自由基，在整个过程之中羟基自由基从反应物一侧进攻并逐渐发生扭转，直至形成一个进平面结构的过渡态结构，这与上一章关于黄酮类化合物B环的研究结果基本一致。

The torsional rigidity, the maximum torque within 10 and its corresponding maximum torsion angle were recorded.

记录扭转刚度、10内的最大扭矩及所对应的最大扭角。

Last year, on a global scale by silicon steel sheet, copper, aluminum and other raw materials driven by rising prices in all, my power tools in the international market price of the full reversal of the declining year-on-year decline, the average price of all prices, but increase significantly.

去年，受全球范围内的矽钢片、铜、铝等原材料价格全面上涨的推动，我国电动工具的国际市场价格全面扭转了逐年下滑的颓势，平均单价全部上扬，而且上涨幅度明显。

In torsion , every groups have obvious effect of the stability of plate and screw structures. At 2.142°,the rigidity of A group is least and the rigidity of E group is most.

在扭转试验中，相同的钢板长度，一定螺孔间距，不同的螺钉数量对钢板螺钉内固定结构系统的稳定性有显著影响。

The VCL method and the displacement method are used to calculate the Stress Intensity Factors of semi-elliptical surface crack at the root of pipe screws, on the basis of which a simplified calculating model for screws contact is put forward so as to analyse the fracture intensity for oil drill pipe screw coupling. For the semi-elliptical surface crack with different shape and deep ratio at the root of female and male screws and the corner of male flange, the SIF has been studied systemically under inter-pressure, tension, bend and torsion loads and the approximate formulas encluding the structure parameters of oil drill pipe screw coupling, deep ratio and the shape parameters of surface crack are developed.

对工程实际中的多种石油钻杆接头螺纹连接件，就公螺纹齿根、母螺纹齿根、公螺纹台阶转角处存在的不同形状、不同厚度比的半椭圆表面裂纹，在拉伸、内压、弯曲、扭转多种载荷作用下的应力强度因子作了系统研究，在大量有限元计算基础上，建立了包含接头结构参数、裂纹形状、厚度比在内的近似计算公式。

Here, we present a patient who received emergency right salpingo-oophorectomy for the wrong impression of torsion of ovarian cyst. The pathology turned out to be EST.

谨提出一例初误诊为卵巢囊肿扭转，接受急诊开刀切除右侧卵巢，后病理证实为内胚层窦肿瘤。

On the basis of the modeling and analyzing of the transmission system of the PQS-3-D elevator for car in the preamble, this article analysis the reason of the small difference of the angular speed, angular acceleration, angular displacement curve between the bilateral symmetry components. Actually, it is the result of that the torsional rigidity of the bilateral drive shafts are different, therefore has made the revision suggestion to the drive shaft parameter.

在对PQS-3-D型汽车专用升降机传动系统建模分析的基础上，分析左右对称传动构件的角速度、角加速度、角位移曲线在系统起动时间内有较小差异的主要原因，发现是由于左右传动轴的扭转刚度系数不同造成的，故对传动轴的参数做了修改建议。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
