摘　　要： 分析了颗粒计数器校准前、后5种尺寸的颗粒数变化情况,并用实验验证了颗粒计数器的校准对滤纸多通试验结果的影响,校准前平均过滤比值均低于校准后的值。此外,分析说明了用颗粒数补偿法来替代颗粒计数器校准会降低试验结果的准确性,明确了定期对颗粒计数器进行校准的重要性。 Before and after of the calibration of the automatic particle counter,the change of five dimensions of the particle is analyzed.The effect of this change for the multi-pass test was validated by the experiment.And the average filtration ration before of the calibration was lower than that of after the calibration.At the same time,it was analyzed and pointed out that the negative effect of the test result when the coefficient of the compensation was used instead of the calibration of the automatic particle counter.It is made sure that the experiment system needed to be calibrated in the stated time.

关 键 词： 颗粒计数器 校准 多次通过 滤纸 过滤比
