颗粒浑液浓度的光学测量方法

摘要

According to theory and practice, based on consistent principles, the optical density nonlinear correction problem in particle concentration measurement was solved based on the generalized Lambert-Beer law. The problem of the effect of particle size on particle concentration measurement was solved using the size index. In addition, the extinction coefficient of the mixed particles was processed reasonably well. Solving these problems is the key to developing the desktop photoelectric sediment analyzer.%在理论与实践相符合原则的指导下，从广义的Lambert-Beer定律出发，提出颗粒浑液浓度光学测量中光密度非线性校正问题的解决方法；使用沉降粒径指标，解决了颗粒浑液浓度测量受颗粒粒径影响的难题；此外，对混合颗粒消光系数的合理处理进行了尝试。这些问题的解决是台式光电泥沙分析仪研制成功的关键。
