不旋转的

For Hu invariant moment having no scale invariance, two modified algorithms are proposed: one is based on the normalized central moment coming from the concept of image square and the other is based on constructing a new invariant moment.

主要贡献如下： 1。针对离散情况下Hu不变矩特征仅仅具有平移、旋转不变性，不具有比例不变性的问题，提出了两种改进算法：一种是从图像正方形概念演变而来的归一化中心矩的修正；另一种是重新构造新的不变矩特征。

Unusual feature of Bergmann was the cocking handle, which was placed at the rear of the receiver, and was operated the same way as on Mauser bolt-action rifle - that is, shooter had to rotate the bolt handle to the left, pull it all the way back, then push it home and rotate back to horizontal position.

伯格曼不寻常的特点是握把，这是放置在接收器的后方，是经营的毛瑟螺栓于行动步枪-也就是射手不得不旋转螺栓处理左边，同样的方式把它的所有回去的路上，然后推回家和旋转回到水平位置。

Base on normal invariant moment and wavelet character, construct wavelet moment and eigenvector, which can rotate, zoom and is no change when moved.

基于一般不变矩和小波特征，构造出小波矩及一组具有旋转、缩放和平移不变性的特征量用于特征提取。

To solve the problem encountered in finding a proper rotation matrix and translation vector, approximate and precise solutions are provided successively. The approximate one has the advantage of utilizing existing solution, with limited range of weight to choose from. The precise one has no limit to weight, and can also prevent the problem of obtaining a mirror matrix of the correct one. Besides, it permits the'hat'to be amplified to fit the size of'head'.

其中近似解可以直接套用现成的公式计算，但是权重的选择余地不大，而精确解则无此限制，而且从理论上解决了不同权重下求解旋转矩阵和平移向量时，可能出现错误的旋转矩阵的问题，并允许在配准时对"帽"进行缩放以适应"头"和"帽"的大小不匹配的问题。

The tactile finger system in the operation is to grasp vessel ectoblastic or operation device, such as suturing needle, to inspect and modify the grasping force and exchange the end device, such as operation scissor or operation sword to achieve the operation of snipping and cutting, to rotate along its axis assisting 6 DOF motion of the robot and to keep the grasping force within 0-100gf and the rotation angle within 360°.

具有力感觉的手指系统在手术中的功能是夹持血管外膜或者是手术器械如缝合针等，进行夹持力的检测和调整；更换指端的手术器械，如手术剪或手术刀，以进行剪断和切割的操作；配合整个机器人六自由度运动的要求，指端器械绕自身轴线旋转；并且夹持力的调整范围是0~100gf，旋转的角度不超过360°。

Atfirst,stress and displacement at the end of collinear crucks are calculated by elasticity me-chanical method,then general solution of twist force at the end of collinear cracks is givenby rotation theory,single crack and double cracks are discussed emphatically.

本文计算并讨论了忽视旋转的传统理论所不能给出的裂纹端部场与场源的相互作用，首先利用弹性力学方法计算了共线裂纹组端部的应力场及位移场，然后应用旋转理论给出共线裂纹组端部的扭转力通解，对单裂纹和双裂纹情形做了重点讨论。
