n: also called index number law, the mathmatic expression describes rheological curve of pseudoplastic fluid.

adj: having the capability of changing apparent viscosity with a change in shear rate. Pseudoplastic fluids gain viscosity when subjected to a decrease in shear rate, and lose viscosity when the shear rate is increased. See shear

n: a kinds of non-Newtonian fluid, its character is that it flows when enforced by slim shear stress.



a complex non-Newtonian fluid without thixotrophy. Flow starts with pressure but apparent viscosity decreases instantaneously with increasing rate of shear.
