On mechanical properties, the strength was raised obviously, fatigue property was unchanged, impact toughness and ductility were reduced.
在性能方面，强度被显著地提高，机械疲劳性能变化不明显，冲击韧性和塑性降低。
2
Objective To analyze the instruments for post stroke fatigue, Fatigue Severity Scale(FSS), Checklist Individual Strength(CIS) and FatigueImpact Scale(FIS).
目的比较疲劳严重度量表（FSS）、个人强度目录（CIS）和疲劳影响量表（FIS）各自的侧重点。
3
And the research about seat safety concentrates on the analysis of static strength, impactstrength and fatigue strength.
