摘要
通过对光阱中的布朗粒子进行动力学方程求解,由解的结果分析得到观测系统的性能要求.结果表明:光阱中布朗颗粒服从Boltzmann分布;对其运动的观测需要纳米量级的空间分辨率和毫秒量级的时间分辨率.
By solving the dynamical equation of a Brownian particle in a optical trap and analyzing the solutions, characteristics of the position measuring system can be obtained. Results indicate that the Brownian particle obeys Boltzmann distribution; in order to measure the motion, the order of nanometer spatial and millisecond temporal resolutions are necessary.
