摘 要：In this paper,the authors discussed the high sensibility of gas Rn to the deformation of rock in the crust by contrasting observation of Rn gas with dissolved Rn in groundwater and by studying the precursors of earthquakes of Rn gas and dissolved *** change of earth tide of rock in the crust can be observed with the methods of gas Rn in *** the 1989 Datong-Yanggao earthquake,the changes of gas Rn indicated that the gas Rn can reveal the slight related changes of stress of rock in the crust in a magnified *** the research of the gas Rn in groundwater,as a new observation item of earthquake precursors in groundwater,has broad prospects.
