摘　　要：回顾了单螺杆挤出机挤出理论的发展历史,并从固体输送、熔融、熔体输送和混合四个方面详细介绍了近10年来单螺杆挤出机挤出理论的最新研究进展。总结了目前在单螺杆挤出领域所普遍存在的能耗高、产量低、混炼差等缺陷,分析了缺陷产生的原因,并针对以上缺陷相应地从如何实现高效输送、高效熔融和提高混炼性能三个方面展望了单螺杆挤出机未来的研究发展方向。The development history of extrusion theory for single-screw extruders was briefly introduced, the latest theories of solid conveying, melting, melt conveying, and mixing were discussed. The existing deficiencies of the single-screw extruder such as high energy consumption, low output, and poor mixing were analyzed. Suggestions for how to achieve a more efficient conveying and to improve mixing performance were also made.
