摘要
讨论了应用定积分和二重积分的知识计算旋转体体积的新方法,并根据理论需要提出了面积矩和面心的概念。
In this paper, a new method for calculating the volume of rotating body is proposed by making use of definite integral and double definite integral. At the same time, the area moment and the area center are brought forward According to the theory needs.
