Conclusions: the proposed less computationally intensive method may be used to precisely calculate the diffusion ellipsoidalsurface area.
结论：本文所提方法计算量较小，可以精确地计算扩散椭球表面积。

The common aim of all such systems is to represent an ellipsoidal shape on a flat surface — distortion in some places is almost inevitable.
这些系统的共同目标是在平面上表示椭圆形状 — 有些地方失真也是不可避免的。

Initial blanks for ellipsoidal objective surface and an irregular surface were calculated and the optimum forming path for a saddle objective surface was designed by the presented methods.
