It is necessary to elaborate on the definition of a fatigue coefficient such as that for ductility . 有必要对疲劳系数,如延性系数的定义作详细讨论。
It is evident that ductility is a desirable property of structural materials required to resist blast . 显然,为要抵抗爆震,结构材料的延性是一个重要的条件。
Ideally, a structure which is to suffer little damage from blast should have as much ductility as possible . 按理想来说,结构的延性愈大则愈不容易为爆震波所毁。
A fact of great importance for geology is that brittle materials such as rocks tend to become ductile when subjected to large hydrostatic pressure . 地质水中一个十分主要的事实是:当受到很大水压时,脆性材料如岩石等有变成延性材料的趋势。
