结果显示：实验侧髌骨倾斜角明显大于对照侧。
The results revealed that the patellar tilting Angle of experiment knees was larger than that of the controls.
侧喷嘴倾斜角度在0度、30度、45度和60度情况下，由于井底涡旋器的旋流作用，导致井底产生旋转，对钻头喷嘴射流产生了影响，以致在45度时出现压力损失最小的情况；
When the inclination angle of a side nozzle is 0, 30,45 and 60 degrees, the eddying flow of the bottom hole vortex device will cause rotation at the bottom hole, affecting on the jet from bit nozzles.
同一侧的耳朵也没有了，他的一只左脚看起来也受过伤，痊愈后的样子变成了个极不自然的斜角，使他看起来总像是在不停地转弯。
He was also missing his ear on the same side, his left foot appeared to have been badly broken at one time, and had healed at an unnatural Angle, making him look like he was always turning the corner.
