摘要：为制定得到符合我国仪器现状、满足对不同测量原理(光阻法和电阻法)、不同测量介质(水和油)、不同测量方式(固定粒径档、可调粒径档和不设粒径档)液体颗粒计数器的分辨力检定需求,对现有的几种分辨力检定、校准方法的优缺点进行分析和比较,最终制定得到具有可靠理论基础和可操作性强的分辨力检定方法,并对该方法进行实验验证。结果表明:该检定方法准确可靠,具有很好的可操作性和适用性。

Abstract：For the sake of obtaining a verification method for the particle sizing resolution of liquid-borne particle counters， which could be applied to those having different principle， different measurand， different measurement mode， the virtue and shortcoming of some present calibrate methods were listed and compared. The two more reliable and reasonable calibrate methods for particle sizing resolution of liquid-borne particle counters were obtained， and some experiments were done to verify the methods. The testing results showed that the method were accurated and reliable，and had good manoeuvrability and applicability.
