摘　　要：利用双螺杆挤出实验中的实验数据曲线，对影响螺杆填充率的诸相关因素进行分析。在螺杆几何结构及螺杆元件组合形式确定之后，不同的操作工况条件下对应有不同的螺杆最大允许填充率。在正常操作中，螺杆的填充率不能大于最大允许值。Using the datum curves from the twin screw extrusion experiment,the correlative factors influencing the fill ratio of screw are analysed.After the screw geometrical frame and the assorted form of screw elements are chosen,there are different biggest screw fill ratios under different opertional conditions.The screw fill ratio cannot be more than the allowed biggest one in normal operations.
