扭转

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.

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。

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.

The results show that when the tunnel is excavated in the single soil layer, the vertical displacement is similar as settlement. When the tunnel is located at the typical soil layers, there are torsions as well as the settlement.

分析结果表明，在单一土层中由于土体的约束作用，结构产生的位移以整体沉降为主，在成层土体中除产生一定的整体变形外还伴随一定的扭转变形。

The influences of length-to-thickness ratio, material anisotropy and torsions effect on natural frequencies and buckling loads were also investigated.

分析中同时考虑了一阶和高阶横向剪切变形、转动惯量、细长比、各向异性、扭转变形等多种因素对组合梁固有频率和屈曲载荷的影响。

According to the UL-incremental method, a new three-dimensional Euler-beam element which taking into account the effects of beam-column、moments and torsions is derived and geometric stiffness matrix expression of the element is given out.

采用UL增量法重新推导了计及梁柱效应、弯曲及扭转效应的三维欧拉梁单元，并给出几何刚度矩阵的显式表达式，编制了相应的三维几何非线性分析程序，对程序的主要功能及新梁单元的可行性进行了考核。

Lots of earthquake disaster phenomena show that structures with torsion modes of vibration have obvious torsions under seismic action, which are occurred together with translational vibration of structures.

摘 要：大量震害分析和观察表明，结构在地震发生时存在着扭转振动，且在地震作用下结构的平扭耦合效应是不可忽视的，在某些情况下甚至是结构破坏的主因。

If torsades de pointes is intermittent and not associated with arrest, administer the magnesium over 5 to 60 minutes IV.

如果尖端扭转性室速是间歇性的，且没有出现心跳停止，可以在5～60分钟内静脉注射镁剂。

A better predictor of torsades des pointesis the time interval between the peak and the end of the T-wave.

扭转性室速的一个较好预测指标是 T 波的最高峰和末尾之间的时间间隔。

Decline in the net value of 40% to 45% and 45% to 50% and 50% to 55% between the gathered most of the funds, lightly position Will be able to reverse the course of events.

在40％的净价值下降之间最聚集的资金为45％和45％至50％和50％至55％，轻轻地位将能够扭转事态的发展。

He had opposed every suggestion for the use of poison gases,as that would violate the Geneva Protocol;at that time Germany alone had manufactured the potentially war-winning lethal nerve gases Sarin and Tabun.

他拒绝了每一个使用毒瓦斯的建议，只因那会违反《日内瓦协议》，而在那时德国已经可以独立制造两种致死毒气：沙林和瓦崩，若将它们投入运用恰恰可能扭转局势将战争引向胜利。
