本文用相邻平衡法建立了均匀外压下的纵横加强圆柱壳平衡方程，提出了求解板格屈曲和肋间壳板屈曲理论临界压力的高精度解法。它能退化到不带纵筋的圆柱壳和单层壳，并提出了板格失稳和肋间壳板失稳工程简化计算公式，故具有较高的精度和广泛的适用性。

By using the method of adjacent equilibrium, this paper built balance equations about a cylinder reinforced by rings and stringers under homogeneous external pressure.The paper has provided the exactest solution of critical pressure for interframe buckling of shell panel and interframe buckling of shell.The solution can degrade into double or single skin without longitudinal stringer panel,and it has high accuracy and extensive applicability.Then simplified engineering formulas about interframe panel instability and interframe shell instability are also provided.
