浙江大学博士学位论文 用标准物质甲苯、正庚烷和水对瞬态热丝法热导率测定仪进行了标 定,结果表明热导率测定仪的测定精度优于1。测定了12种纯物质(包 括标准物质和常见的有机溶剂)在253K.303K内每间隔10K的热导 率,和8个二元体系在253K.293K内每间隔20K的热导率。其中,乙脐、丙烯晴、四氢吹喃、1,2一二氯乙烷、甲苯一正庚烷、正庚烷一 乙醇、正庚烷一丙酮、丙酮一乙醇、乙酸乙酯一丙酮、乙醇一乙酸乙酯、四氯化碳一乙醇等体系的实验数据尚属首次测定。将实验结果与本文模 型计算结果比较,12种纯物质的总平均偏差为0.
The thermal conductivities of twelve pure compounds(including the three standard substances)in the temperaturerange from 253K to303K(increment10K),andeight binary systemsin the temperaturerange from 253K to293K(increment20K), have beenmeasured.
