文摘The thermal conductivity of glycerine aqueous solution was measured at 20 ℃ by means of a transient method with error in parallel analysis <1%. The equation correlating the concentration with thermal conductivity was presented . The time of measurement was 1 s. The method avoids the heat convection of liquid sample due to its rapidity and is promising for on line analysis in production control.
