【摘要】 分析了光阻法颗粒计数器中的关键技术 ,指出颗粒对光的遮挡属于一种消光现象。根据光散射理论 ,推导出消光计数技术的光能和粒径之间的关系式。通过大量数值计算 ,说明光阻法仅是消光法的一种特例。还详细分析了消光理论在实际应用时的影响因素 ,并给出了相应的解决措施。更多还原

【Abstract】 Light obscuration is due to the light extinction by single particle, the reason is discussed in this paper Base on the theory of light scattering, the corresponding relation between the light energy and particle diameter is educed A great of numerical calculations showed that light blockage is a special type of extinction Also, the influence factors of light extinction count technology are analyzed in detail, and the solutions to this application are proposed更多还原
