摘要: In recent years, a number of workers have studied the stability deep lakes such as Lake Tanganyika, Baikal and Malawi. this paper, methods that can be used to determine effect components on equation state are examined. The PVT properties Lakes been determined by using apparent molal volume data for major ionic lake. estimated (densities, expansibility compressibilities) found in good agreement with (P) seawater diluted same salinity. This is similar earlier work showed rivers estuarine waters could also from seawater.
