Combined with the former experiment for solidconveyingzone and melting zone, the torque for extruding zone was obtained.
结合课题组过去所做的固体输送段和熔融段两段的实验，得出了各实验条件下螺杆挤出段的扭矩。

Motion and force of the solid plug in the solidconveyingzone were analyzed deeply in the two equivalent cases of the inner screw.
在固体输送段对内螺杆的两种等效情况下固体塞的运动和受力作了深入分析。
