摘　　要：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.The thermal conductivity of glycerine aqueous solution was measured at 20 ℃ by means of a transient method with error in parallel analysis <1%.
