摘　　要：The rheological properties of two cellulose samples,e.g.Cotton 1 and Wood 2 were investigated,including the dependence of non-Newtonian Index,structure viscosity and zero shear viscosity on concentration and temperature of the solutions.Non-Newtonian Index n decreases with concentration and increases with temperature,structute viscosity increases with concentration and decreases with temperature.Zero shear viscosity decreases in an index manner with temperature and viscose flow activation energy is higher than that of viscose solution.The reactive property of Cotton 1 is better than thatThe rheological properties of two cellulose samples, e.g. Cotton 1 and Wood 2 were investigated, including the dependence of non- Newtonian Index, structure viscosity and zero shear viscosity on concentration and temperature of the solutions. Non - Newtonian Index n decreases with concentration and increases with temperature, structure viscosity increases with concentration and decreases with temperature. Zero shear viscosity decreases in an index manner with temperature and viscose flow activation energy is higher than that of viscose solution. The reactive property of Cotton 1 is better than that of Wood 2.
