Non-standard Design for Concave Curvature Radius of Belt Conveyor
带式输送机凹弧段曲率半径的非标设计
Meanwhile, a concave reflector with suitable curvature radius and large section radius improves the levitation capabilities of the potential well near the reflector under mode 4.
另外,采用适当曲率半径和较大截面半径的凹球面反射端能够提高模式4下靠近反射面的一个悬浮位置的悬浮性能。
The paper describes a high resolution, high accuracy and simple method of measuring dymamic angle by means of optical self-collimating of concave mirror curvature center.
用四球面反射镜曲率中心光学自准方法,通过测量自准像位移来计算弯沉角,是一种高分辨率、准确、简单地测量方法。
