unit tangent的例句大全

In this paper, we give an explicit representation of the Sasaki metric on a vector bundle. In particular, we get Sasaki metric on unit tangent bundle T_1S~ ( 2n+ 1), by which we calculate the volume of the Hopf vector field V_h.

本文给出了矢丛上Sasaki度量的局部表示，特别得到单位切丛T1S~（2n+1）上Sasaki度量的表达式。

And so that means that any vector u, any unit vector tangent to the level set of g is going to be perpendicular to the gradient of f.

也就是说，任何向量u，任何与g的水平集相切的单位向量，应该要与f的梯度垂直。

The stress strain relationship in different principal stress load direction can be reflected in the anisotropy of tangent elastic ratio or strain increment in load direction induced by unit stress increment in load direction.

不同主应力加荷向的应力应变关系各向异性可以反映在切线弹模以及加荷向单位应力增量引起的加荷向应变增量的差异中。
