摘　　要：采用密度瓶法测定常压下喹啉、十氢萘及其混合物和四氢萘、正庚烷及其混合物在不同温度下的密度.结果表明,它们的密度均随温度升高而降低,密度与温度间存在很好线性关系.详细讨论了这两组混合物(喹琳和十氢萘按体积比1∶1混合,四氢萘和正庚烷按体积比2∶1混合)的密度加和性问题,由作图和计算均可得知这两组混合物密度具有很好的加和性.这为将来待测的复杂混合物——煤液化油全馏分密度提供了理想的测试分析平台.The density of quinoline/decalin/ their mixture and tetralin/n-heptane/their mixture are measuried with the hydrometer method at different temperature and normal atmosphere. Obtaning the trend that density is lower with temperature rising. There is very good linear relationship between density and temperature. The additive property of two groups mixtures were carefully discussed： Densities of two kinds of mixtures had additive property by simple graphical procedures and calculating. It is very significant to measure the density of coal liquefied oil in future.
