摘　　要：介绍应力场、超声波场、电磁场、高能辐射场等能量场在塑料动态成型加工过程中的应用,并且概述了各种场致作用对塑料成型加工的影响及其相关机理。国内外最新研究表明,超声波场、剪切应力场等能量场的应用可有效地改善塑料熔体的流变性能及其制件的组织形态,并提高其力学性能。The application of stress field, ultrasonic field, electromagnetic field and high-energy radiation field in the dynamic molding processing of plastics is introduced. And the effect of all kinds of fields on the processing of plastics and the mechanism are summarized. According to the recent studies at home and abroad, the application of ultrasonic field, shear stress field etc can improve the rheology property of plastics melt and the part morphology effectively, and the mechanical property can be enhanced.
