摘　　要：本文介绍了粒度测定仪气体干粉分散器中自动给料系统的设计依据,建立其数学模型,通过理论和实验分析证明该系统的运动是简谐振动,指出了振动周期与平衡点有关参数的关系,这对系统的设计具有重要的指导意义。This paper introduces the design foundation of the automatic supply system in gas dry-powder disperser for size determing-instrument, sets up its mathematic model, prives that the motion of this system is simple harmonic vibration through theory and experiment analysis, and points out the relation of the period and balance point of vibration with the concerned parameters. It has very important direct significance to the design of the system.
