摘要
对定容式 ＰＶＴｘ实验装置的恒温、测温和测压系统进行了改进，温度和压力基本测量精度提高到±５ｍＫ和±０．４ ｋＰａ．对 ＨＣ１２７０／ＨＦＣ２２７ｅａ、ＨＣ２９０／ＨＦＣ２２７ｅａ和 ＨＣ１７０／ＨＦＣ２２７ｅａ二元物系进行了 ＰＶＴｘ实验研究．
PVTx behaviors of HC1270/HFC227ea, HC290/HFC227ea, and HC170/HFC227ea were experimentally investigated with a new version of PVTx apparatus. 60 measurements were taken with a precision of 5 mK, 0.4 kPa, 0.2% and 0.3% for temperature, pressure, specific volume, and composition respectively.
