移动车辆荷载反复作用会导致桥梁疲劳损伤甚至破坏，移动荷载识别是桥梁健康监测的重要措施之一。

Moving loads identification is one of the important measures for health monitoring of bridge because the cyclic action of moving loads may lead to fatigue damage or even failure of the bridge.

结论：MT对反复脑缺血再灌注损伤有显的保护作用，其机制可能与抑制脑水肿及抑制脑内升高的MDA、NO有关。

CONCLUSION: MT shows significantly protective effect against repeated ischemia reperfusion injury in mice, and the mechanism might be related to inhibit the rise of MDA and NO in brain tissue.

结果建立一种适合低周期反复荷载作用下的损伤模型，并进行了损伤与弦转角的关系分析，从而对其损伤机理、损伤过程及损伤的影响因素有更进一步的了解。

The damage model has been made and the analysis of the relation damage and turn Angle has been studied to give a better understanding of the damage theory, damage course and damage effect factors.
