friction circle

基本解釋

It's a circle, we have no friction.
是個圓環(huán)，沒有摩擦。
When the pump shaft and the packing heat generated by the friction depends on water-sealed tube to live on the water to seal circle to fill cool!
當泵軸與填料摩擦產(chǎn)生熱量就要靠水封管住水到水封圈內(nèi)使填料冷卻！

We use K to analyze the probability of occurrence of sliding friction circle, and demonstrates it in the structural plane stereographic projection.
用分散性指標K表示塊體滑動面的分散性，由此分析滑動摩擦圓的出現(xiàn)概率，并表示在結(jié)構(gòu)面赤平投影圖上。
