摘　　要：本文介绍了作者在改装的JN-1型倒扭摆真空内耗仪上进行的变形金属位错链长统计分布参数测试工作。数据处理结果表明,通过相对动态模量及位错密度的分析和估测,可以确定位错链长统计分布参数值大小并决定该条件下的位错链长统计分布曲线。从而为进行变形金属位错链长统计分布动态研究提供了除TEM外的另一条有效实验途径。In this paper we introduced the work to determine the parameters of dislocation link length distribution by inverted pendulum with deformation and load system which is improved by authors. The experimental results for pure Ni wire show that the parameters and curves of dislovation link length distribution can be obtained by analyzing the internal friction coefficient Q- and dynamic modulus Md/Mo.So this is an effective technical method for dynamical investigation of dislocation link length distribution in deformed metal.
