So, first it's concentric circles that tells us that we have a shape that's a solid of the graph is going to be a surface of revolution. Things don't change if I rotate. 因此，首先它是一些同心圆，这告诉我们,这个图形是一个旋转得到的曲面,当旋转它的时候并没有发生变化。 - 2
"We're on the brink of a new lighting revolution," says Jerry Simmons, head of the solid-state lighting programme at America's Sandia National Laboratory. 美国桑地亚国家实验室固态照明项目首脑Jerry Simmons称，“照明技术革新即将濒临”。 - 3
Then combined with teaching example, detailed analysis on intersection curve of normal revolution solid is provided, theoretical basis is advanced for computer graphics. 并结合实例，细致的分析了常见的回转体相贯线，为计算机绘图提供了理论依据。
