摘　　要：本文根据有关文献所提供的关于柔性石墨缠绕垫的试验结果，分析了其力学性能和密封性能的内在联系，提出了基本型垫片的“拐点”应力计算式，建立了泄漏率、应力、介质压力的关系式。Based on experimental results of wound flexiblegraphite saskets from references ,the internal relations between mechanical property and seal property were analysed, a stress calculation of inflexion points of basic gasketswas proposed. the correlations of leakage,stress .and medium pressure were established .
