摘要: FOR infinitely diluted suspensions of rigid spheres, Einstein1 derived on a rigorously theoretical basis the formula η = η0 (1 + kc),... (1) where is viscosity suspension, pure solvent, c concentration by volume and k 2·5 constant. It has been shown that also valid for non-spherical particles, factor being function their shape, rigidity Brownian movement. For elongated > 2·5.
