摘要
提出了用分形理论来建立微粒布朗运动特征模型的设想，并从理论上阐明了它的有效性。在此基础上进行分析，得到了模型的分形特征和微粒尺寸参数间的关系。结合图象信号处理技术，可从计算的分形维值中获取粒度信息，进而可得到一种超细微粒粒度测试的方法。
Brownian Motion is one of the important characteristics of submicron particles.On the basis of observatiorl for Brownian motion of particles,the authors present a medel to describethis physieal process by usin g fractal theory a nd this medel is proved to be valid in theory.Throughfurther an alyzing,we establish the relationship between fractal characteristics and particle sizeparameters.Combining image signal processing technique,particle size information can be obtainedby computing fractal dimension values,and then a new method for particle sking will be developedinfuture.
