摘　　要：推导并计算了不可压圆筒结构的扰动增长方程及具有弹性的运动方程 ,讨论了氧气 乙炔混合气体聚爆明胶圆筒的耦合扰动增长规律 ,研究结果为会聚结构的瑞利 泰勒不稳定性实验提供了很好的理论依据。Feedthrough perturbation growth equations in an incompressible cylinder geometry and motion equations in elastic cylinder were derived.Feedthrough perturbation growth in cylindrical gelatine driven by explosions in oxygen acetylene gas mixture are discussed and analysed.Calculatal results are in good agreement with S. T.Weir et al′s reports.The results are useful for studying Rayleigh Taylor instability experimentally.
