| 摘 要： | 本文主要利用南北地震带上的水点资料,研究了水氡的年变化形态,分析了年变化产生的原因,进而提出水氡正常变化的含义,即在无震期间,水氡实测值在一年内随时间变化所表现出来的某种规律性变化形态,而且这种变化形态每年都具有相似的重复性。作者认为,水氡的正常变化可分为三种类型:夏天高冬天低的“弓”型;夏天低冬天高的反“弓”型和近直线型。某个水点水氡的正常变化被研究清楚以后,依据它所属的类型,就可以推知所受的干扰因素,並能及时判断出是否出现了异常。

| Abstract: | There have been reports on the characteristics of the changes of radon contents in the groundwater before the occurrence of art earthquake so as to predict an earthquake in China and abroad. However, what is their change during the period of no earthquakes? Few reports have been presented so far. In this paper, the materials are mainly from the stations located on the South-North seismic belt. First of all, we study the change shape of the curve of radon contents for a year. Secondly, we analyse its causes of formation. In accordance with what we have mentioned a definition of the normal changes of radon contents in the groundwater is given. It means that during the period of no earthquakes the data of radon contents in the groundwater obtained form observation shown that there are certain regular change shapes for a year and these shapes are similar to each other every year. The pattern of change of radon contents in the groundwater is known as their normal changes. According to the definition, thief normal changes can be divided into three patterns:(1) The radon contents increase in summer but fall in winter; (2) The radon contents fall in summer but increase in winter and; (3) the radon contents are almost a constant for a year. When the norma lchanges of radon contents in a certain spring or a drill hole have been clearly known, and according to thief shapes, it can be inferred what facters which have disturbed the normal changes of radon contents are and then we can judge in time whether they are abnormal or not. |
