摘　　要：在不同温度和压力下测量自制试验装置内气相部分的氡浓度,计算氡在对应温度和压力下的溶解度系数,并用自适应神经模糊推理系统(ANFIS)建立了根据温度和压力预测氡溶解度系数的ANFIS模型。结果表明,氡在水中的溶解度系数随温度升高而降低,随压力降低而降低。预测氡在水中溶解度系数的ANFIS模型能够给出足够精度的预测结果,为预测氡的溶解度系数开辟了新途径。Radon concentrations were measured in an apparatus at different temperatures and pressures. Radon dissolution coefficient was calculated at corresponding temperature and pressure. ANTIS model was established to predict radon dissolution coefficient at different temperatures and pressures. The results show that radon dissolution coefficient in water decreases with pressure, but increases with decreasing temperatures. The ANFIS model can predict the radon dissolution coefficient accurately.
