备注

通过深入研究水氡观测中标定K值意义,使用平行样观测等方法检测K值的准确性,并基于实际工作中总结的经验,归纳出提高水氡观测中标定K值的准确性和可靠性的方法,使观测氡值真实反映地下水中氡浓度变化情况,为获取地震孕育与发生提供更可靠的信息。

Making an intensive study of the significance of K-value calibration in water radon observation,we test the accuracy of K-value by parallel sample observation method etc. Based on the summary of the experience from practical work,we generalize the method of improving the accuracy and reliability of K-value calibration in water radon observation to make sure the water observation radon value could reflect the real variation of radon concentration in groundwater,and could provide the reliable information for obtaining the preparation and occurrence of earthquake.
