我国某地盐湖重水分布特征的研究

THE DISTRIBUTION OF HEAVY WATER IN SALT LAKES IN A CERTAIN DISTRICT, CHINA

Heavy water eoutcnts were determined for brines from Some salt lakes, and for water samples from rivers, springs and oil field by temperature-float method. Because the salt lakes studied are situated in cold, arid region of high altitude, the heavy water content in concentrated brines is much higher than that in rivers and springs due to vigorons evaporation, with a maximum value of 5.9 γ higher than that in running water of Peking. Discussion is also given to the dependence of heavy water variation upon season, depth of lake water, density, the degree of brine metamorphism,and crystallization of minerals containing crystalline water.
