摘要：

The shear viscosity coefficients of saturated and compressed liquid 1,1,1,2-tetrafluoroethane (R134a), 2,2-dichloro-1,1,1-trifluoroethane (R123) and 1,1-dichloro-1-fluoroethane (R141b) have been measured with a torsional crystal viscometer at temperatures between 170 and 320 K and at pressures up to 30 MPa. The fluidities (reciprocal viscosity) increase linearly with molar volume at fixed temperature and increase weakly with temperature at fixed volume. We have correlated our data using empirical fluidity-volume-temperature equations and have compared the data of others with the equations.
