【Abstract】 Based on the high permeability of helium on quartz film and the working principle of ion pump, a helium monitor was developed for continuous detection of helium in dissolved gas and escaped gas of underground water. The composition and construction of the instrument are described. The instrument has been used preliminarily at seismological stations for monitoring preliminary phenomena of earthquake. The results obtained are satifactory and demonstrate that the instrument has potential and practical values for earthquake forecast.更多还原
