【Abstract】 The thermal conductivity of aqueous solution of Na Cl and H2 SO4 were measured at 2 5℃ using transient method. The appartus was calibrated using four reference samples,whose thermal conductivities had been known.Acquiring experimentaldata and analysing experimental resultsare completed by a computer.The average errors are less than1 % .The time of measurements is one second.The method is rapid and convient.更多还原
