里面还说道,
For example, cutting through cardboard (which often has hard embedded impurities), toughness becomes extremely important, because micro-chipping is often the reason for edge degradation. Whittling very hard wood, strength becomes very important for edge-holding, because the primary reason for edge degradation is edge rolling and impaction.
有人翻译了:
比如,切割含有很多硬微粒的纸板的时候,韧性发挥着最重要的作用,因为这个时候刀子变钝主要因为微观的崩刃。在切削硬木的时候,强壮性发挥着最重要的作用,因为这个时候刀子变钝主要因为微观卷刃和挤压。作者: adofcmu 时间: 2012-11-28 23:47
