聲波具有非侵入性，可控制的顆粒尺寸範圍廣泛，本研究成功地利用聲波對微米尺度的粒子進行分離。在我們的研究中－首先，使用模擬軟體COMSOL進行了調變波的動態分析；之後，根據顆粒的不同材料和尺寸，我們規劃和設計了一系列的實驗，通過調整不同參數並分析其對分離效果的影響，而不同密度或直徑的顆粒表現出不同的沉降速度，需要通過實驗獲取分離過程中調變波的參數；最後，在不同條件下對單個或多個顆粒進行分離實驗。而目前我們做到的實驗階段，我們已可以成功分離數十微米的二氧化矽，進一步地分析和討論結果，我們預期在加工液的材料回收及溶液純化等方面有潛在應用價值。;In this study, we successfully utilized sound waves to separate micrometer-scale particles. We performed dynamic analysis of modulated waves using simulation software COMSOL. Based on the different materials and sizes of the particles, we designed experiments to analyze the separation effects by varying parameters and assessing their impact. Different particles exhibit varying sedimentation velocities depending on their densities or diameters, necessitating experiments to determine the parameters for modulated waves in the separation process. Finally, we conducted separation experiments for single or multiple particles under different conditions and analyzed and discussed the results and data. The non-intrusive nature of sound waves used in this experiment, along with their ability to control a wide range of particle sizes and manipulate micrometer-scale particles, makes sound wave-based separation experimentation a reasonable choice.
