The locus of space tangent point and the arc segment of deck at side are obtained based on the above conditions.

在此基础上，求出首圆弧空间切点线和甲板边线的修正段。

In this paper, some relations of the invariants concerning the simplex and its tangent point simplex, are given and then, an inequality for the dihedral angles of a simplex is also presented.

本文首先给出单形的不变量和它的切点单形的不变量之间的若干关系式，然后再给出一个关于单形二面角的不等式。

That is how we reformulated it. That means we take our curve and we figure out at each point how big the tangent component I guess I should probably take the same vector field as before.

这是另一种形式，它意味着,要求出每点处向量在切向量方向的分量,我还是用之前那个向量场吧。

So the velocity at any part of the curve is tangent to the curve at that point.

曲线上任意一点的速度,都在该点和曲线相切

That means that you want to pick, ultimately, a point on this-- this line is tangent to the efficient portfolio frontier with all the other assets in it.

那意味着你会最终会在这上面选一个点-,这条直线是与有效边界相切的,后者包含了所有的资产组合。

At any point on the graph you can take the derivative, which will be tangent to the curve at each point, and its numerical value will be what you can call the instantaneous velocity of that point and you can take the derivative over the derivative and call it the acceleration.

在图上的任意一点,你可以进行求导,得到曲线上每一点的切线斜率,所得到的数值,即为该点处的瞬时速度,然后你再求一次导,得出它的加速度
