unit tangent

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。

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。
