normal axis

The dominant joint system strikes roughly east , normal to the axis of La Veta Synclche.

主要节理系大致为东西走向,垂直于罗韦塔向斜轴.

Adaptive slicing is realized by the calculation of the position of tangent plane of modeling surface, the angle of between the normal section line and the slicing plane, the curvature of normal section line in z-axis direction and radius of curvature.

计算出造型曲面的切平面位置、法线与分层平面的夹角、Z向法截线的曲率和曲率半径，实现优化分层。

The specimens are designed into two different groups, one group of which subject to bending around axis parallel to bed joint orientation, and the other subject to bending around axis normal to bed joint orientation.

试件设计成两组，其中一组沿齿缝弯曲，另一组沿通缝弯曲。

Therefore, the bending moment may cause normal stress at the axis of gravity, and the concept of equivalent axial force is induced.

因此弯矩在形心处要引起正应力，从而引出所谓等效轴力的概念。
