1. This
ellipse crosses inside the orbit of Neptune, which means Neptune is sometimes the outermost planet.
这种椭圆跨越，这意味着海王星有时最外层的行星海王星内，轨道。
2. Using effective macro-programs, it designs the NC processing program for
ellipse surface, and realizes the NC machining of complex surfaces.
采用合理有效的宏程序，完成椭圆部分数控加工程序的编制任务，实现了复杂曲面的数控加工。
3. The cursor can become an eraser tool and erase anything previously entered, or it can become an
ellipse tool and draw any number of new
ellipses.
光标可以变成橡皮擦，擦除先前输入的任何内容，也可以变成椭圆工具，绘制多个新的椭圆。
