It influences not only the pressure Angleof mechanism, but also the curvature of earn contoUrs.
它不仅影响机构的压力角，而且还影响其轮廓曲线的曲率半径。
2
The curvature rate and well curvature plane Angle can be used to make a good description of the influence of the well trajectory parameters on the side fo.
弯曲平面倾角和井眼曲率的有机结合可以很好的描述井眼轨迹空间形状对钻头侧向力的影响。
3
The Angle can be calculated based on principle of optical triangulation and so the curvature of corresponding position based on structure parameters.
