摘要
应用高聚物流变学的理论对塑料熔体在浇注系统中的流动行为进行了研究，从熔体流变行为角度去设计浇注系统，以克服凭经验设计的不足。
The reology for highpolymers is applied to study the rheologic behaviour of molten plastics in the gating system, and a rheological method for designing gating systems is developed, which can overcome the defficiencies encountered in empirical designs.
