三、 工作原理： Working principle
將粉末量筒固定在機械振動裝置上，振動電機帶動機械振動裝置上下振動，裝有粉末的刻度量筒隨機械振動裝置而發生有節拍的振動，隨著振動次數的增加，量筒里的粉末逐漸振實，振動次數達到設定的次數后，機械振動裝置停止振動，讀出刻度試管的體積，根據密度的定義：質量除以體積、從而求出振實后的粉末密度。
Powder cylinder fixed in the mechanical vibration device, mechanical vibration device vibrate under driven by vibrating motor, the calibration test tubes which containing powder vibrate with the mechanical vibration device, with the increase of vibration frequency, the powder in the measuring cylinder gradually compact by vibration, When vibration frequency reaching setting the number of times, mechanical vibration device will stop the vibration, Read the volume of the calibration test tube, according to the definition of density: mass divided by volume, thus find out the powder density after compaction.
