摘　　要：根据压电测量的基本原理，用压电薄膜传感器对装配条件Ｔ３种单圈填料的侧压系数、摩擦系数和衰减系数以及３种填料的１５种组合形式的轴向压力和侧向压力的分布进行了测试，为研究动态条件下组合填料的密封性能提供了可靠的依据。The lateral pressure coefficient, frictioncoefficient and decay coefficient of threekinds of single-circle packing as well asaxial and lateral pressure distributions of 15combined types from three kinds of packingare measured on the basis of the basic principle of piezoelectric measurement by piezoelectric thin film transdusers, which provides a reliable basis for study on combinedpacking sealing performance under dynamiccondition.
