摘要
本文简单介绍了在250—370K温区内一种用于固体或液体比热精密测定的自动绝热量热装置。用标准物质α-Al_2O_3和正庚烷检测了该装置的可靠性。首次报导了用此装置测定二乙基甲酰胺饱和液体比热值。
An automatically-adiabatic calorimeter is described briefly, which can be used for precision measurement of heat capacity of solid and liquid in the temperature range 250-370K. The reliability of the apparatus is verified by measuring the heat capacity of α-Al_2O_3 and n-heptane(aceepted as the standard substances). The experimental heat capacity data of DEF measured by the appara tus are reported.
