7·In a certain range. drawing force is reducing along with the increasing of drawing speed, which was reached by test.

通过试验得出拉拔力在一定范围内是随着拉拔速度的提高而降低的。

8·Based on the rules of drawing force, drawing process is divided into four stages: start, first contact, entire contact, stable.

并将拔制力分为四个阶段：起始、初步接触、完全接触、稳定。

9·The thinning drawing force is calculated through deforming work method and slip-line method irrespectively, and the results are compared in this paper.
