摘　　要：研制了一套基于毛细管法的用于测量气体溶解在液体中达到饱和状态时的饱和溶液黏度的实验系统。为了扩大黏度的测量范围,本文采用两根不同尺寸的毛细管并联,使实验台更为便捷可靠。利用该实验台分别测量了异丁烷(R600a)与角鲨烷、二甲醚(DME)与角鲨烷组成的饱和溶液在温度范围为303.15~343.15 K内的黏度数据。同时,还利用Setchenow模型和Hind模型对实验结果进行关联,对比分析了模型的计算精度。An experimental system based on capillary method was developed to measure the viscosity of mixtures of gas dissolved in liquids at the condition of saturation state.In order to expand the range of viscosity measurement,a parallel branch with two different size capillary tube was used to the new system.It makes the experimental system more convenient and reliable.Based on the experimental system,the liquid viscosities of squalane saturated with isobutane(R600a)or dimethyl.ether(DME)were measured at the temperature range from 303.15 K to 343.15 K.The experimental results were correlated by Setchenow model and Hind model,and the calculated accuracy of each models was compared and analyzed.
