”回转体体积计算“程序可以计算出一个复杂物体的程序，当然这个物体一定要有可以计算的某个部分组成，如一个物体有1个圆台、2个圆柱、3个球冠、4个球台组成，则体积可算-" Terms of the volume of revolution,"　a complex program can calculate the object' s program, of course, the object must be composed of one part can be calculated, if an object has a round table, two columns, three spherical cap, 4 tables in composition, the volume can be considered
