转动

At whatever pace the pirouette (half-pirouette) is executed, the horse, slightly bent in the direction in which he is turning, should, remaining 'on the bit' with a light contact, turn smoothly round, maintaining the exact cadence and sequence of footfalls of that pace.

3.3。无论用哪种步伐做定后肢回旋，马体都应当向著它转动的方向稍稍弯曲，保持'受衔'和轻微的接触，流畅地旋转，保持正确的节奏和该种步伐运步的顺序。

The piston's transverse motion across the cylinder and rotation around piston pin, so called secondary motion, was studied by analytical method.

采用模拟分析的方法研究了活塞沿缸套的横向运动和绕活塞销的转动，也就是所谓的二次运动。

The pitman arm swings from one side to the other (or forward and Backward on some cars)as the steering wheel is turned.

转动方向盘时，转向摇臂从一侧摆动到另一侧(在某些汽车上是前后摆动)。

What is the difference between a Natural Pivot and a pivoting action?

右轴转和轴转动作之间有什么区别？

The shapes of the melting solid surface may be concave, convex or plane, while the perimeter of plane contact regions may be rectangular, circular, elliptical, parabolic and arc curve. The types of relative motion reviewed here are the movement of a solid PCM melting inside a heated capsule, the movement of a hot body through a melting solid medium, slide contact and rolling contact. The contact melting may be caused by temperature difference, pressure difference, friction and viscous heating. Finally, the research regions in the future are summarized.

内容包括各种形式的接触熔化，可归纳为：在接触形状上可以有凹、凸与平的面，而接触的周长可以是矩形、圆形、椭圆形、抛物线形与弧形曲线；相对运动的类型有固体相变材料在加热容器内熔化，加热体通过熔化固体介质的运动，滑动接触与滚、转动接触；引起接触熔化的原因有温差、压力差、摩擦与粘性热。

From the primary mirror and a plane mirror the composition of focus image on the tube side, the focus of its focus, said Newton.

在镜筒侧面可以安置多种不同的终端设备，转动平面镜就可使其中一种处于工作状态。

The R/C frame structures were modeled with bar system and the column was modeled with multi-springs. The concrete and steel bars in column were considered as springs in order to reflect the coupling influence between the axial force and the moment-rotation relationship, the hysteresis of springs is based on the material properties and the rotation of column section is followed the plane assumption. The moment-rotation of beam section was modeled with trilinear hysteresis model.

混凝土框架分析模型采用杆系模型，其中柱采用多弹簧模型，柱端的混凝土和钢筋作为弹簧考虑以便反映柱轴力与弯矩－曲率的耦合关系，弹簧的滞回关系根据材料特性确定，柱截面的转动符合平截面假定，梁截面弯矩－转角关系采用三折线滞回关系模型。

The rotational inertia of an arbitrarily triangle uniform plane is calculated by a simple method. It is pointed out that principal axes can be deduced from the calculation.

摘要用一种简单的方法计算了均质的任意三角形平板刚体的转动惯量，并由此结果给出一般三角形的惯量主轴。
