The area calculating formulas of burning surface and channel section have been derived by the grain geometry.
根据装药几何形状，导出了在火箭发动机工作过程中燃烧面积及通道截面积变化规律的计算公式。
It is assumed that the propellant consists of a finite volume of elements and the burning surface consists of a finite area of elements.
该方法认为装药由有限个体积微元组成，而燃面由有限个面积微元组成。
