| 摘 要： | In this study a measurement instrument of scrooping sound has been develope.Thefollowing results were obtained by means of measurement and analysis for the frequencyspetrums of scrooping sound of silk : 1 The scrooping vibration is mainly composed of S- S( stick-slip vibration) ,F- V(free damping vibration) and S- C( characteristic high frequency vibration) vibrations. 2 The scrooping sound of silk mainly depends on F- V and S- S vibrations and be-longs to lower frequency sound,while the effect of S- C vibration is limited. 3 The wave and the vibration equations as well as some fromulas of relative physicalproperties have been established on the discussion about the stick- slip vibration. 4 The critical condition producing stick- slip vibration is( μs- μd)> 0.
