摩擦感度是测定固体推进剂危险性能的重要指标之一。它直接关系到推进剂研制、生产、运输和使用过程的安全。 我国现用的测试设备是WM-1型摆式摩擦仪(即苏联的K-44-Ⅲ型)。 Friction sensitivity is one of the most important indexes to measure the dangerous performance of solid propellant. It is directly related to the safety of propellant development, production, transportation and use. Our current test equipment is the WM-1 pendulum friction instrument (ie the Soviet K-44-Ⅲ type).
