摘要
介绍了根据Lambert-Beer定理并采用多波长消光法测量颗粒粒径分布的方法。提出了基于数值模拟和数理统计对多波长消光法粒径测量下限进行估计的方法。通过数值模拟分析讨论了入射光波长、颗粒相对折射率和透光率对粒径测量下限的影响。研究为多波长消光法粒径测量在实际应用中的可行性提供了指导。
The measurement method of particle size distribution by multi-wavelength extinction based on Lambert-Beer theorem was introduced.An approach for estimating the lower limit of particle size measurement by multi-wavelength extinction method in terms of numerical simulation and mathematical statistics was proposed.The influence of incident wavelength,relative refractive index of particles and light transmittance on the lower limit of measurement was analyzed and discussed via numerical simulation.It can provide guidance for the potential practical applications of particle size measurement by multi-wavelength extinction.
