基于麦克风优化螺旋阵列的声学成像装置在局部放电定位中的应用研究

Gaoya dianqi
现有的特高频、紫外等局部放电检测手段在缺陷定位方面存在一定问题，文中选取更为有效的超声定位检测手段，将其与麦克风阵列技术和波束形成算法相结合，考虑电力设备局部放电的声学信号特点，基于单臂和多臂螺旋阵列特点，优化阵列设计形成阿基米德单臂曲线，并与相匹配的延时波束成形算法相结合，以满足当前局部放电定位场景的需求。进一步，基于上述技术设计形成声成像装置，实现以热力图的形式实时显示声源在空间的分布状态。通过在输电线路、变电站等典型电力设备场景中的应用，声学成像装置能清晰地定位局部放电的点 ...

维持性血液透析患者合并睡眠障碍的风险列线图模型的构建与验证 附视频

Linchuang shenzangbing zazhi
目的 分析维持性血液透析（maintenance hemodialysis,MHD）患者睡眠障碍的危险因素，并构建风险预测模型。方法 选取2018年1月至2022年12月期间收治的198例MHD患者为研究对象，采用回顾性分析法，依照患者是否合并睡眠障碍将患者分为睡眠障碍组（n=134）及非睡眠障碍组（n=64），通过单因素及多因素Logistic回归分析筛选出MHD患者睡眠障碍的危险因素；利用R软件建立MHD患者合并睡眠障碍的列线图模型，采用绘制受试者工作特征（receiver operating ...
