摘要：

The viscosity of aqueous ammonium bromide solutions is measured at 0.1-1.0 mol kg(-1), 278.2-323.2 K, and 0.1-375 MPa, using a high-pressure rolling-ball viscometer. The activation energy (E(v)) for viscous flow and Jones-Dole's B coefficient are estimated. E(v) against pressure yields a concave curve with a minimum and B yields a convex one with a maximum. These phenomena are attributed to pressure, temperature, and concentration effects on the water-structure.
