《压力容器安全技术监察规程》将几何容积列为一项重要参数,以利于安全技术监督和管理。本文利用数字上的古尔金定理,推导出计算具有正、反向曲线的变径段其曲线部分的旋转体的容积表达式。
“Pressure Vessel Safety Technology Supervision Regulations” to the geometric volume as an important parameter in order to facilitate safety supervision and management. In this paper, by using the Guergin theorem, we derive the volumetric expression of the rotating body in the curve part of the variable-diameter section with positive and negative curves.
