摘　　要：提出了两种电测布点标值的方法:分数值法和带分数值法。这种标值法可使大量布点中的每一测点处的角变形、错边及该点距某一基点的距离明确和一目了然;并依角变形和错边计算式为基础制做了角变形和错边计算图表;和根据电测值对被测球壳几何缺陷形貌的分析预测进行了尝试;同时也进一步证明了所用“球壳”角变形计算式的准确性。Two ways to make the electrical gaging point clear have been raised. They are'fraction sign and algebra sign'. Such signs can make clear and easy discernment thesize of angle deformation,alternate edge and the distance to the base point at every gag-ing point which belong to the amount of electrical gaging point. On account of the for-mula of angle deformation and alternate edge,a nomographic chart of angle deformationand alternate edge of 'spherical shell' has been built. Based on the measured stress ofangle deformation,we try to analyse and estimate the geometrical fault form of sphericalshell. At the same time,we further proved the accuracy of account formula of angle de-formation.
