osculating plane

The bi-normal component of jerk ( or the time rate of force change ) is used to describe the rotational physical figure of acceleration ( or the force ) with osculating plane .

急动度（或力变率）的副法线分量描述了加速度（或力）随密切面旋转的物理图像。

A tracing algorithm for calculating the intersection curves of two free-form surfaces by using their osculating plane is presented in this paper .

提出了一种利用密切平面对两自由曲面进行追踪求交的算法。

Then , discuss the methods for calculating the equations of the tangent line , the normal plane , the osculating plane , the binormal , and the rectifying plane ;

讨论了如何才能很快地做出切线，法面，密切平面，副法线和从切平面方程的方法；

In thes paper , from geometric object angles , some definitions of osculating plane of a space curve at any point are given by using the limit and the concept of contact order , and the equivalence of these definitions is proved .

本文将从几何直观的角度，利用极限的思想及切触阶的概念给出空间曲线在一点的密切平面的定义，并给出这些定义之间的等价性。
