Abstract:	本研究成功利用聲波使微粒進行沉降從而達到分離。首先利用模擬進行調變波之動態分析，再針對不同微粒進行實驗規劃與設計，以確認各個參數對實驗之影響。而不同密度或不同粒徑之微粒皆會產生不同之沉降速度，因此需透過實驗取得調變波之參數進行分離實驗。最後依據單顆或多顆微粒進行不同情況之分離實驗，並對其結果與數據進行分析與討論。而本實驗所使用之聲波不具侵入性，且可操控之粒徑範圍廣，因此選擇聲波進行分離實驗之開發。;This study successfully uses sound waves to separate particles. In order to confirm the feasibility of the method, we also use simulation to analyze the dynamics of the modulated wave. The separation status is analyzed by different parameters, such as active time and non-active time. Since different particles have different sedimentation velocity, various parameters of the modulated wave are obtained through experiments. These parameters will contribute to the success rate of the separation experiment.
