摘要
利用可视化双螺杆挤出机进行挤出观察实验，记录、描述并分析了同向双螺杆挤出中的固体输送现象，根据现象可把固体输送过程分为三个阶段。在此基础上提出了固体输送的两区物理模型，两区指散粒体区和粘连区。在这两个区域中，物料运动的本质不同，可见对其数学描述也将不同。
With visualized twin screw extrusion experiment,solid conveying phenomena in twin screw extruders are observed,recorded,described and analyzed.The solid conveying can be devided into three stages.Then a solid conveying physical model——two region model is established.“Two region” here refers to the dispersed solid region and the adhesive solid region.The two regions are different essentially,and we predict different mathematical descriptions for them.
