【Abstract】 In order to tackle the present difficult problems in viscoelasticity measurement of blood and other biofluids with Couette and cone-plate rheometers, the effect of inertia of inner cylinder and sample on the measurement result is studied. Rheological models of the instruments are reconsidered. Based on theoretical analysis of the flow state of the non-Newtonian fluid,a corrected method for calculating Theological parameters of sample is proposed.更多还原
