轴心

The earth rotates on its axis once every 24 hours.

地球每24小时依其轴心自转一次。

Remain its accuracy by rotating 360 degree around its axle center for Square and cylindroid vials.

它的精度主要是指圆柱和方水准器的沿轴心360度翻身。

The finite element models of axial tension member and eccentrical tension members are established with ANSYS finite element program.

4、用通用有限元软件ANSYS建立了混凝土轴心和心受拉的有限元模型，并得到了受拉构件的应力云图、变形图及开裂图，并与理论结果了比较。
