摘　　要：文章对凹型加肋锥-环-柱结合壳稳定性进行了模型试验研究,观察到凹环壳段失稳的一个特殊现象。通过对这一特殊现象的深入分析,作者提出肋间壳板"诱导"失稳的概念,并对"诱导"失稳产生的条件及其特性进行了探索。The experiment research on stability of ring-stiffened concave cone-toroid-cylinder combined shell is presented. A special phenomenon of buckling of toroid shell is observed. By further analysis of this special phenomenon, a new concept of ＂induced＂ buckling of frame shell is put forward. The characters of ＂induced＂ buckling and conditions which can lead to this phenomenon are studied.
