| 摘 要： | 在对已有的振动盘黏度计改进的基础上，利用高纯氮气对改进后的实验装置进行了标定．为了检验装置的可靠性，测量了温度为300K、压力为0．1～4．5MPa时的氩气黏度，实验结果与标准值的最大偏差为0．879／6，平均偏差为0．37％．用此装置对制冷剂R152a在温度范围为300～346K、压力范围为0．1～1．0MPa时的气相黏度进行了实验研究，并利用所得实验数据拟合得到了R152a的气相黏度方程，方程计算值与实验数据的最大偏差为0．37％，平均偏差为0．11％，可以满足其他研究和工程应用的需要．

| Abstract: | The oscillating-disk viscometer in our laboratory was improved and calibrated with nitrogen at room temperature.In order to check the reliability and accuracy of the viscometer,the gaseous viscosity of argon was measured at 300 K and pressures up to 4.5 MPa,and the mean absolute deviation was 0.37% and the maximum deviation was 0.87% compared with the reference data.In addition,the gaseous viscosity of R152a was measured at temperatures from 300 K to 346 K and pressures up to 1.0 MPa using the oscillating-d... |
