椭圆长轴 meaning in English

transverse

The aim of this study is to explore the concentrating effects of both the electric current density and the stresses in the plate due to the existence of the elliptic hole
其研究重心是定量计算椭圆孔对电流密度以及板内应力分布在椭圆长轴端点处的集中效应。
There is angular between the longer axes of the ellipse and the axes of the shaft , moreover , the angular is variable with the magnitude and the direction of the load
本文证明该椭圆长轴和传动轴应该呈一定的夹角，而且夹角值随工作载荷的大小和方向的变化而变化。
