基于模型确认的结构概率损伤识别方法研究进展 总被引:3,自引:0,他引:3
基于静动力特性改变的结构损伤识别方法在过去几十年中得到了长足发展。相对于确定性的损伤识别,基于概率统计理论框架的损伤识别方法能够更好地反应损伤问题的不确定性本质,是一种非常有发展潜力的损伤识别方法,有望解决当前大多数损伤识别方法对于测量误差和噪声敏感的问题,从统计意义上实现复杂工程结构健康监测早期损伤的诊断。在回顾结构确定性损伤识别方法的基础上,主要介绍不确定性损伤识别方法和有限元模型确认的研究进展,分析比较各种方法的优点和不足之处;最后对有待进一步研究的问题和基于模型确认的概率损伤识别方法发展趋势进行展望。 相似文献

Factors affecting the extraction of polar environmental constituents from water have been investigated using polar weathering products from Ekofisk crude oil as test substances. Such factors include pH, choice of solvent and chemical nature of the polar constituents.Continuous extraction using ethyl acetate resulted in good reproducibility and showed a high efficiency compared to the more direct methods using a separatory funnel. 相似文献

Hydraulic conductivity profiling with direct push methods 总被引:3,自引:0,他引:3

Spatial variations in hydraulic conductivity (K) are a primary control on contaminant movement in groundwater, but characterization of these variations has proven difficult. Over the last two decades, significant progress has been made in utilizing Direct Push (DP) technology to characterize K variations in unconsolidated settings. Profiling methods have been developed based on empirical correlations between K and more readily evaluated formation properties and on the formation response to water injection or extraction. The latter (hydraulic) methods appear to have the most potential. Initial work on these methods involved adaptation of conventional well tests, but recent efforts have better exploited DP capabilities. The High-Resolution K and continuous Direct Push Injection Logger (DPIL) methods are the most promising approaches. Both provide high-resolution (0.015?m) K profiles, although the DPIL profile is only qualitative in nature. Currently, the K range of both is approximately 0.001 to 60 m/d, but that range should increase in the near future. 相似文献

This article combines a review of literature with observations from an empirical study that examined how five children aged 6 to 10 years experienced nature in a botanical garden setting with a focus on the behavioural, sensory, affective and cognitive dimensions of these experiences. Visually expressive methods (sculptures, drawings, photography and sand tray pictures) enabled children to highlight aspects of their experiences in nature that were memorable and important. The theory of optimal arousal and the circumplex model of affect frame the results. Experiences of nature, as communicated by the children in this study, emphasised the sensory and affective dimensions of experience. Findings also demonstrate that these children sought out optimally arousing experiences that were influenced by challenge and novelty. The circumplex model of emotion and theory of optimal arousal have not been extensively applied to the study of children’s experience. The concept of interest is also explored in relation to research findings. They, in combination with a committed attention to all four dimensions of experience are important conceptual tools in understanding children’s interaction with nature. This article also outlines how these findings contribute to practitioners’ efforts to connect and re-connect children with nature. 相似文献
