| 摘 要： | 静宁东峡泉水氡昌１９８７年投入观测的。资料连续可靠，１９９０－１９９７年连续在全省地台资料评比中被评为Ⅰ类观测资料。用计算机对该泉多年资料进行处理后，有一个完整的夏高冬低的正弓形年动态图像，而且与历年观测值的多次拟合函数有较好的显性。

| Abstract: | Radon in groundwater of the Dongxia spring was put into observation in 1987,and its data were continuous and reliable.Based on the judgement of data anomaly by using nonlinear regression and hydrochemically practical processing method,the anomaly that exceeds the annual dynamic value by two times residual standard deviation can be regarded as seismic anomaly.The radon data have shown obvious anomaly reflection before the earthquakes around the boservation station. |
