In the fields of industrial automation and robot, there is a wide requirement for rotation position servo control.

在工业自动化和机器人领域，存在大量的旋转位置伺服控制需求，因此，对气动旋转位置伺服控制的研究具有实际的应用价值。

We analyse the structure of magnetic rotary encoder,its work principle,the recording media on the magnetic drum and the magnetic sensor,and introduce the application of MRE,the development prospect and Point out that MRE is very important for the development of high technology industry in the future.

论述了磁旋转编码器的结构、工作原理、磁鼓记录媒体和磁阻传感器的特性，介绍了磁旋转编码器的应用领域和使用功能，并对其发展前景进行了展望。

This will change the reference point to the 3D Cursor. The default was the median point of all items selected. In other words, we're forcing the center of rotation or the center of mirroring to be wherever the 3D Cursor is.

这将会强制旋转中心点永远处于3D cursor的位置，前面提到过，旋转中心点不仅仅是选中的中心，还是镜像，缩放等等操作的中心点。

Using the basic dynamic equation of rotary non-inertial system, the basic law of object s movement in the reference system of rotating about fixed axis , and the conditions of momentum conservation and conservation of momentum moment of objects are educed.

利用旋转非惯性系中的基本动力学方程，导出在定轴旋转参照系中物体运动的基本规律，以及物体动量守恒和动量矩守恒的条件。

Series BD-QT quarter-turn boiler drains offer an innovative alternative to old-fashion multi-turn type boiler drains.

系列BD-QT只需旋转90o即可开启/关闭的锅炉排泄阀对于老式多旋转类型的锅炉排泄阀来说，是一种具有创新意义的替代品。

On the one hand, because of the short action time, it is impossible to get enough time to circumvolve instruments or to circumvolve the physical fields being measured so as to scan in all directions, so the physical fields can only be measured through several instruments; on the other hand, because the physical fields are partly screened or the operator domain is too limited, the measurement directions are limited, too.

一方面，因为作用时间短，不可能有充足的时间使仪器旋转或使被测物场旋转来全方位扫描，只能固定几个方位的探头同时进行测量；另一方面，由于物体被部分遮挡或作用域小，使观测方位受到限制，也只能在测量中用少量的探头。

The moment of a force; the measure of a force's tendency to produce torsion and rotation about an axis, equal to the vector product of the radius vector from the axis of rotation to the point of application of the force.

转矩，力矩一种测量产生扭转和绕轴旋转趋势的力的单位，等于从旋转轴到力作用点的旋转矢量

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
