摘要
静电收集法测氡仪要求有高而稳定的收集效率,温湿度对其影响较大,排除温湿度的影响是困扰仪器开发者多年来的一大问题。通过实验探讨温湿度对静电收集法测氡仪收集效率影响的作用机理,实验得出,收集效率既与相对湿度有关,又与绝对湿度有关,而不是其中某一个的单元函数,并应用团簇的形成与变化机制和中和机制对实验结果做出了理论解释。
Radon monitor based on electrostatic collection demand for a high and stable collecting efficiency, temperature and humidity influences it greatly. How to get rid of the influence of temperature and humidity is an important problem puzzled instrument developers. The paper discussed the influence of temperature and humidity on the collecting efficiency through experiment. The results show that eoUeetion effieieney is related to both relative humidity and absolute humidity, not a function of one of them. The formation and diversification of clusters and neutralization mechanism apply to explain the experimental results.
