摘　　要：根据纸浆悬浮液所具有的特殊流变特性，该文对纸浆在圆管中的流动状态提出了新的见解。用弹塑性力学理论建立了纸浆在圆管中流动时压头损失的数学模型，可为制浆造纸管道输送系统的设计提供理论依据。According to the special hydrodynamic beliaviour for pulp,a new concexit of pulpflow state in the pipe is advanced in the paper,The mathematical method of head loss for pulpflow in the pipe is also put forward.The mathematical method of head loss for pulp flow in pipeis modelled by employing elastoplastic mechanics theory.This mathematical model may offer atheoretical basis for the design of pipe transpcrt system in pulp and paper mill.
