【摘要】 本量热计利用准稳态原理设计而成,主要用于测定含油地层岩样的真比热,测试范围0.1—9.0MPa、室温≈550K,绝热控制精度<±0.5％,标准样品纯铜和石英玻璃的测定值与TPRC的常压值偏差约±1％。仪器具有测试快速、换样方便、自动控温,结果直接打印和精度较高等优点。更多还原

【Abstract】 An adiabatic calorimeter based on quasi-steady method for measuring the true specific heat of underground oil rocks in the range of 300-550K and 0.1-9.0 Mpa has been designed and constructed. The experimental results of standard samples of pure copper and quartz plass are compared with the values recommended by TPRC, the deviations are within ±1%. The special features of the apparatus are: fast measuring, easily replacing sample, high accuracy and with results indicator.更多还原
