Abstract

Based on analysis and deduction to Stoke's falling principle, some questions of particle size measurement in Stoke's falling principle were probed and analyzed.The calculation forms of maximum measured particle diameter and minimum measured particle diameter in the principle were put forward.It will attach importance to pratical application.

Keywords：particle size measurement;Stoke's falling principle; fluid mechanics;Brownian movement
