摘　　要：本文对轴对称线布载荷作用下碟形扁壳的非线性稳定问题进行了分析，得到了各种常见边界条件下碟形扁壳特征关系的二次近似表达式·讨论了几何参数β。A theoretical analysis is presented for the snap_buckling behavior of dished shallow shells under axisymmetric distributed line loads. The second approximate formulae of elastic behavior of dished shallow shells with various boundary conditions are qiven, and effects of geometrical parameters γ,β and k on non_linear behavior are discussed.
