After analyzing the characteristic of the rigid plane motion and the shortcomings of classical digital image correlation algorithms, the phase-angle position of the rigid body in the 2D image was characterized by 1D sequence signals using the method of equiangular sampling feature extraction based on circle windows. Then the generalized correlation algorithm for estimation of time delay based on wavelet transform was used to acquire the angular displacement. Finally the ultrasonic radiation force acted on the micro-component was determined by the relation between force and motion.

在研究检测对象刚体平面运动特点和分析传统数字图像相关算法局限性的基础上，采用基于圆周窗口等分角采样的特征提取方法，将二维图像中刚体的相角位置信息表征为一维采样时序信号，并通过基于小波变换的广义相关算法来估计位移前后特征序列的时延，得到刚体的旋转角位移，从而利用力与运动量的相互关系确定出作用于微构件的超声辐射力。

In Ptolemaic cosmology, a small circle, the center of which moves on the circumference of a larger circle at whose center is Earth and the circumference of which describes the orbit of one of the planets around Earth.

First of all, the improving feeding helix can not only get material into the ball mill successfully, but also increase ventilated proportion; Secondly ,making use of all sorts of new scaleboards can reform the working condition of skive substance and raise the material adaptability; Third, separating storehouse board, have not only increased control material to flow, and balanced each storehouse smash the function of ability, but also realize thickness pellet grade role; Grind tail storehouse choose hyperboloid drum liner, in axial and circumference direction have incline curved surface, can not only increase steel ball lateral grade , but also still raise steel forge , steel ball grind efficiency.

进料口螺旋的改进，不仅解决了堵料现象，而且加大了通风面积；各种新型衬板的使用，对研磨体运动状态的调节以及对物料的适应性都有了较大的改善；隔仓板不仅增加了控制料流及平衡各仓粉碎能力的功能，而且可以实现粗细颗粒的分级作用；磨机尾仓选用双曲面衬板，在轴向和圆周方向均有倾斜曲面，不仅能够增加钢球的横向分级，还能提高钢锻、钢球的研磨效率。

The direction is normal to the line of centers, i.e. motion is circumferential

该方向垂直于中心连线，即运动是沿圆周方向的。
