水氡时值序列和日值序列中的潮汐波分量

TIDAL WAVE COMPONENTS IN HOURLY VALUE SEQUENCE AND DAILY VALUE SEQUENCE OF RADON CONTENT OF GROUNDWATER

本文用潮汐波最优谱分析法处理了一些水点的水氡时值资料和水氡日值资料,结果显示兰州五泉山水点水氡时值序列中存在着与理论固体潮相一致的半日波和日波分量;山东聊城、天津张道口、甘肃平凉等水点水氡日值序列中存在着与理论固体潮相一致的半月波、月波分量。上述事实说明,水点条件好、观测质量高的水氡资料能反映出地壳潮汐应力的变化。

In this paper, we have computed the data of hourly values and daily values of radon content by means of the optimal spectrum-an alysis method of tidal wave. The results show that there exist semidiurnal and daily wave components in hourly value sequence of radon content measured at Wuquanshan spring of Lanzhou, which are consistent with the theoretical earth tide; there exist semimonthly and monthly wave components in daily value sequences of radon content measured at Liaocheng drill of Shandong Province, Zhangdaokou drill of Tianjin City, Pingliang spring of Gansu Province, which are consistent with the theoretical earth tide. It has proved that drills and springs having good environmental conditions and the data having good quality, the change of radon content can reflect the change of tidal stress of earth crust.
