The kinematic analysis of a planar cam mechanism can be realiaed by the method that the higher pair is substitute for lower pair, and then it is equivalent to a planar linkage. The main point by the way is how to calculate the radius of curvative of planar cam profile.

對于平面凸輪機構(gòu)的運動分析可以用高副低代的方法將其轉(zhuǎn)化成平面連桿機構(gòu)來進行，而高副低代后關(guān)鍵的問題是如何在書籍平面凸輪廓線的基礎(chǔ)上求解凸輪的曲率半徑一A黄视频图片。

In the meantime the radius of curvative of the planar cam profile should be also tested in the synthesis of the planar cam mechanism.

另外久久艹视频，在平面凸輪機構(gòu)的綜合中亚洲国产精品一区二区四季，一般也要驗算凸輪輪廓曲線的曲率半徑久久久久精品久久久久免费。

A method of determining the radius of curvative of a planar cam profile by Sterling Differentiation is proposed, and then an example is given to demonstrate it.

本文詳細(xì)介紹了如何用斯梯林插值公式求解凸輪廓線為等間隔離散點的平面凸輪曲率半徑方法十八女免费毛片，并給出了一個例子加以驗證。

Methods: Under peridural anesthesia, the right rectus incision was adopted. First, the vessels in lesser curvative of stomach was amputated and ligated. Second, splenic artery was ligated to deflate spleen .Then ,splenic artery and renal vein were amputated and side-to-side anastanosised with each other. Result: Of the 36 cases,the portal free pressure decreased by different degree in 23 cases, unchanged in 10,and increased in 3 postoperatively. The follow-up ranged from 1 to 5 years.
