高致病性禽流感发生风险评估模型的建立

Zhongshan Daxue xuebao. Yixue kexue ban, 2008
【目的】 对高致病性禽流感发生的风险进行评估,为该病制定科学有效的控制策略提供理论依据?【方法】 首先,通过对已发生的高致病性禽流感相关资料的分析,结合已有的研究成果,确定高致病性禽流感发生的风险因素;然后通过改进现有对高致病性禽流感发生的风险评估方法---层次分析法,利用改进后的模糊层次分析法确定风险因素的权重;最后应用多指标综合评分法计算出风险概率,建立高致病性禽流感发生风险评估模型?【结果】 将该模型对2008年春季我国各省份禽流感疫情发生情况的风险预警评估结果与今春实际情况进行对照检验 ...

基于振动法检测的瓷绝缘子损伤探讨

Gaoya dianqi, 2009
为减少在役支柱绝缘子断裂事故,提高其检出率及检测速度,笔者首次研究了将整体损伤检测法——振动法引入绝缘子检测的可行性,并设计了4个试样绝缘子的自由悬挂与地面放置状态试验,用力锤激励绝缘子使其振动并采集加速度响应信号,对采集的信号分别进行频谱分析和小波包分析,以提取损伤特征参数,并比较这两种信号处理方法的优劣。结果表明,用3层小波包分解的信号处理方法可有效检测出支柱绝缘子4 mm深的裂纹损伤。
