| 摘 要： | 用流体力学的方法，导出了圆偏振光作用下光镊光场中液体粘滞系数、激光功率、微粒转速及微粒尺度等参量之间的关系，根据推导结果得出了一种通过测量液体中微粒在聚焦圆偏振光作用下的旋转速度进而计算液体粘滞系数的新方法，并用Friese等人的一组光致旋转实验参数进行了验证。

| Abstract: | A relationship of some paranleters including dynamic viscosity of a liquid, laser power, rotation speed and scale of the particle is induced in a focused circular polarized light beam by the method of fluid dynamic. According to the relationship, a new method to measure dynamic viscosity of a liquid is obtained. By using Friese＇ s experimental parameters, the correspondence of dynamic viscosities from this new method and from traditional methods is confirmed. |
