semi-transverse axis

The ellipsoid is defined by its semi-axis, and the flattening of the ellipsoid or the semi-axis.

这个椭球面通常以它的长半轴和短半轴或者长半轴和扁率定义.

For 45# steel car semi-axis, through determining its chemical components, microstructure, hardness, inclusion, observing the breaking section and analyzing its heat treat process, the main reason for its break is found out, the improving measures proposed.

通过检验45钢汽车半轴化学成分、金相组织、硬度、夹杂物，观察断口形貌及分析其热处理工艺，确定了造成汽车半轴断裂的主要原因，继而提出了改进措施。

An ellipsoid name , semi-major axis, and inverse flattening.

参考椭球体, 椭球半长轴和.

Two pairs of point on the ellipse are used to determine the location of the center of the ellipse, orientation, and the two semi-axis.

用椭圆上的两对点确定椭圆的中心、旋转角度、长半轴、短半轴等参数。
