bending under tension的意思|示意

When leveled by bend the strip is applied by a tension, under the influence of the tension and repeated leveling by bending strip is permanently elongation deformed, improving shape of strip.

而在弯曲矫直的同时，对带钢施加一定的张力，在张力和反复弯曲矫直的作用下，带钢产生永久的延伸变形，从而改善了带钢板形。

Effects of temperature on impact strength of PVC and the effects od load rate on mechanical properties under tension and bending load of PVC are Studied.

本文研究了加载速率对PVC拉仲、弯曲性能的影响规律及试验温度对PVC冲击强度的影响。
