室温及疲劳循环应力低、循环周次多的断口粗糙度大，纤维拔出较长；

Fracture morphology is more rough in room temperature, low fatigue stress and more fatigue cycles, but the length of fiber pullout is longer.

我们一直遵循一个循环的开发流程，并发现以一周为循环周期对我们来说最适用。

We're following an iterative development process - and found out that a length of one week seems to work best for us.

The circulatory system which we'll talk about in a couple of weeks, the heart, the blood vessels, and the blood work together to form a totally internal function.

例如过几周我们要讲的循环系统,心脏,血管,血液,三者协同工作,形成一个完全在体内发挥作用的体系
