应用MATLAB对氡析出率测量过程中不同体积和底面积下集氡罩内氡浓度随时间的变化规律进行模拟计算，并用实验对计算结果进行了验证。结果表明：在氡析出率测量时保持抽气流率不变的情况下，集氡罩的体积、底面积分别与平衡氡浓度及氡浓度的平衡时间存在正比的关系，并且集氡罩内的充气均匀性影响着测量的准确度。通过本次实验获得了较为合理的集氡罩体积和底面积的组合，即：5．7×10－3 m3、5．94×10－2 m2；抽气流率为0．6 L／min。

By using MATLAB,the authors did simulation about how the radon concentration changes with time during the measurement of the radon exhalation rate in different radon cover sets which have different capacity and basal area , and after this ,the authors did an experiment to prove the results .The results suggest that:the equilibrium concentration and time of radon is proportional to the capacity and basal area of radon cover sets when keeping the flow rate of air -bleed constant during the measurement of radon exhalation rate and the accu -racy of the measurement is influenced by the homogeneity of the gas in radon cover sets .Besides , the research also advised a pair of reasonable parameters of the capacity and basal area of a radon cover set , that are 5.7 × 10 -3 m3 and 5.94 ×10 -2 m2 respectively;the flow rate of air-bleed is 0.6 L/min.
