建立并完善了一套高温流动型热导式量热装置，实现了量热与色谱在线分析的有机结合。对该系统的仪器常数、热量常数、时间常数进行了精确的标定，并采用标准物质氮气、正庚烷等对仪器的准确性进行了考察，测量结果误差在2.2%～4.7%之间。同时还实测了吸热型碳氢燃料S-1，R-1等的热裂解热沉值。S-1在700℃时的热沉为2.99MJ/kg，而R-1的热沉为2.82MJ/kg。

A novel high-temperature flow calorimetric system of conduction type was designed, with a built in chromatograph suitable for on-line analysis. The thermal and time constants at 700℃ of the calorimeter were calibrated by a sample electric energy method. The accuracy of the equipment was also validated with standard samples such as heptane and N~2. The heat sink values of endothermic hydrocarbon fuels S-1 and R-1 at 700℃ were determined to be 2.99 MJ/kg and 2.82 MJ/kg, respectively.

Key words: CHROMATOGRAPHY, ON-LINE ANALYSIS, PYROLYSIS, CALORIMETERS, NITROGEN, HEPTANE
