现行中学数学课本中关于圆锥体积的证明是根据祖(目恒)原理推出的,本文立足于集合论及运动论,试图给出又一种证明,以期讨论。论点一线由点运动而成,面由线运动而成,体由面运动而成,质点为生成线集合、面集合、体集合的最小元素; The proof of the conical volume in the current middle school mathematics textbook is based on the principle of ancestral (constant) principle. This article is based on set theory and theory of motion and tries to give another proof in order to discuss it. The first line of the argument is formed by the point movement, the surface is formed by the movement of the line, and the body is formed by the movement of the surface. The particle is the smallest element of the generation line collection, face collection, and body collection;
