硬度测试在电站锅炉检验中的应用

硬度测试是一种非破坏性的测试手段,操作简单、速度快、适用范围广,广泛应用于锅炉检验。作为能量转换的核心设备,电站锅炉的安全可靠与否直接影响整个电厂的生产效率与安全。锅炉长期运行在高温高压的环境下,且受到多种腐蚀性介质的共同作用。因此,锅炉材料性能会发生较大变化,需定期对其进行硬度测试,及时发现材料的潜在退化问题,防止重大事故的发生。文章将重点研究如何在电站锅炉检验中应用硬度检测技术。

Validity and reliability of three methods of stiffness assessment

Background：Stiffness is commonly assessed in relation to injury and athletic performance.The purpose of this research was to compare the validity and reliability of 3 in vivo methods of stiffness assessment using 1 cohort of participants.Methods：To determine inter-day reliability,15 female netballers were assessed for stiffness twice within 1 week using unilateral hopping（vertical stiffness）,free oscillations of the calf,and myometry of various muscles of the triceps surae.To establish convergent construct validity,stiffness was compared to static and dynamic strength measurements.Results：Test–retest stiffness results revealed that vertical stiffness produced moderate to high reliability results and myometry presented moderate to very high reliability.In contrast,the free oscillation technique displayed low to moderate reliability.Vertical stiffness demonstrated a significa t correlation with rate of force development during a squat jump,whilst myometer stiffness measurements from 3 sites in the lower limb revealed significan correlations with isometric rate of force development.Further,significan negative correlations were evident between the eccentric utilisation ratio and various myometer stiffness results.No relationships were established between the free oscillation technique and any of the performance measurements.Conclusion：These results suggest that vertical stiffness and myometry are valid and reliable methods for assessing stiffness.
