摘　　要：球罐球壳板极板结构特殊,在设计过程中采用简单的数学计算公式难于计算出每块极板的精确质量。以球壳板几何尺寸计算结果为基础,利用球面三角理论进行了桔瓣式及混合式球壳极板理论质量的计算。该方法简单快捷,准确度高。For the special structure of polar shells of the spherical tank, it is difficult to calculate the exact quality of each polar shell using a simple mathematical formula in the designing process. Based on calculation results of physical dimension of the spherical shell, the theoretical weight of petal-like and combined-style spherical shell was calculated by the spherical trigonometry method. This method has the characteristics of simple, quick calculation and high accuracy.
