扭转角

Using laser Doppler effect , based on measurement of the rotate speed of single section , the speed difference of double sections is measured and integrated , then the torsion angle of rotating shaft on torque effect is got. The non2contact torque measurement is realized , and dynamic monitoring of rotary machine equipment is achieved.

利用激光多普勒效应，在单截面测量转轴转速的基础上，采用双截面测量转速差并积分得到转轴在扭矩作用下的扭转角，实现扭矩非接触测量，达到回转机械设备的动力监测的目的。

As the jacket is bent or twisted, adjacent engagement elements move together into engagement with each other, limiting the bend radius or twist angle of the jacket, and thus of the fiber optic ribbon cable or other protected line.

当护套弯曲或扭转时，毗邻的约束零件一起移动进入彼此咬合的状态，从而限制护套的弯曲半径或扭转角，并借此限制带状光缆或其它被保护的导体的弯曲半径或扭转角。

Problems of single footing are classifying about results、determination of dimension of combinational column on combinational foundation、determination of bending moment on superface of combinational foundation and determination of partly press area when there is angel between column and foundation; the problems of strip foundation are determination of torsional moment on some section in checking torsion resist.

独立基础中的问题主要是基础计算结果的归并、双柱合并基础合柱尺寸的确定、双柱合并基础顶面弯矩的求法及柱相对基础有转角时局部受压计算底面积的确定；柱下条形基础的问题是抗扭验算中总扭矩不为0情况下截面扭矩的确定。

Twisting vibration of main transmission shaft during working, smaller dedendum comer R than the normal and lower material yield strength were the main reasons leading to main transmission shaft failure ahead.

主传动轴工作中存在扭振，齿根转角R偏小和材料屈服强度偏低是导致主传动轴提前失效的主要原因。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
