摘　　要：本文应用流体力学理论,分析了液体中的粒子在离心力作用下运动时的受力情况,建立相应的数学、物理模型。通过分析、计算得到粒子在离心管中的运动规律,并用Mathematica软件做出相应的函数图形。The force conditions of particles in liquid which moving under the centrifugal force are analyzed in this paper based on hydrodynamic theory, then the corresponding mathematical and physical models are established. The motion law of particles in centrifuge tube is obtained through analysis and calculation, and the corresponding function graphic is made by Mathemafica software.
