摘　　要：研讨了碟形封头几何特征方程、体积、表面积、质量、接管长度、下封头切线至裙座筒体上端距离和碟形封头的自动作图等问题 ,提供了关于碟形封头液位与体积的关系和在碟形封头上设置盘管等问题的参考文献 ,较完整地解决了碟形封头在设计。The equations of geometry features, volume, surface area, weight, the length of nozzle in dished head, and the automatic plotting of dished head were discussed. The references about volume calculation at difference liquid level and how to set coil in dished head are also offered. The geometrical calculation questions of dished head which are frequently met in design, production and use were solved in some degree.
