They disappear these days at the rate of 25 a day, and I mean regardless of our behavior.
每天就有25个物种消失,我的意思是无论我们做了什么。
If the failure is defined as the final fracture of a component, then both S-N curves and crack growth rate curves reflect the fundamental material behavior under fatigue loading.
如果都把一个构件的最终断裂作为疲劳破坏的定义,则S - N曲线和裂纹扩展率曲线均是反映金属在疲劳载荷作用下的基本材料特性。
The compound of Alkali Surfactant Polymer (ASP) is a kind of viscoelastic fluid, its rheological behavior can be formulated by power law model in simple shear flow within medium shear rate.
就其流变性而言,聚合物溶液和碱—表面活性剂—聚合物(ASP)复合体系均属粘弹性流体,但在中等剪切速率的简单剪切流动条件下,其流变性可用幂律模式描述。
