And reduction affects drawing temperature little and its increasing lowers drawing force.
变形程度对拉伸温度影响小，变形程度的增大使拉伸力下降。
The drawing tension increases with the increase of drawing ratio and speed, and with the decrease of drawing temperature.
随着拉伸比、拉伸速度的提高和拉伸温度的降低，拉伸张力增大。
With the cooperative control of drawing temperature and feed speed, the final hole structure can be effectively controlled by tuning the applied pressure.
在温度和送料速度的协调控制下，通过调节气压参数可有效控制气孔结构。
