静压和总压的分布规律比较相近，沿半径方向的分布呈现较好的轴对称性。

The static pressure distribution is similar to the total pressure, and they all show symmetry along the radius direction.

成形压力沿半径方向呈不均匀分布，可用线性或二次函数曲线进行近似表示。

The pressure distributing law is non-uniform along radius direction, which could be expressed approximately as the linear or quadratic function curve.

结果表明：缸体的径向变形是轴向位置的函数，半径方向的应力是径向位置的函数。

The results show that the radial deformation is the function of axial position and radial stress is the function of radial position.

You just need to remember what's happening to z effective, which really tells us what's happening with all the trends, and once you know z effective, you can figure out, for example, what direction the atomic radius should be going into.

你只需要记住有效核电量的规律，实际上它会告诉我们所有的规律，只要你知道了有效核电量的规律，你就可以判断，比如，原子半径会向着哪个方向发展。
