Gaoya dianqi, 2021 电力变压器结构、运行工况复杂,影响其健康状态的因素众多,建立有效的变压器健康状态评估模型对其状态进行准确评估是十分必要的。文中提出一种考虑变压器历史运行工况影响的变压器健康状态评估模型。从油色谱试验、电气试验、油化试验数据及现场评估等方面提取相关重要指标作为定量指标和定性指标,通过主客观组合权重和岭型隶属函数完成基于定量指标的变压器状态初步评估结果;考虑变压器历史工况建立定性指标对初步评估结果进行合理修正,完成对变压器健康状态的评估。最后以宁夏地区1台110 kV主变验证了该评估方法的有效性和准确性 ...

应用Illumina MiSeq测序技术对腹泻北平顶猴肠道菌群的分析
野生动物学报, 2021 为探寻可能导致北平顶猴（Macaca leonina）腹泻的菌群及其变化规律，分别采集6只健康和6只腹泻北平顶猴的新鲜粪便，应用Illumina MiSeq高通量测序技术测定其肠道菌群的结构以及腹泻过程中肠道菌群的动态变化。结果表明：健康组肠道菌群的Shannon指数（P=0015）、Chao 1指数（P=0014）、ACE指数（P=0032）较腹泻组高。在门水平上，腹泻组肠道中拟杆菌门（Bacteroidetes）、变形菌门（Proteobacteria）和未鉴定细菌（unidentified ...

Gaoya dianqi, 2022 传统变压器状态评估方法,多关注设备当前状态分析,缺少全方位预测其潜在健康状态方法,也无法确定变压器将来的故障发生概率。本文提出了一种基于自适应概率神经网络的变压器健康状态评估方法。该方法,首先从变压器内部本体特征和外部实时监测环境两方面,确定变压器健康状态指标因子,并进行数据预处理得到不相关的指标因子;然后,根据指标因子和样本标签,引入自适应参数训练,训练出用于预测的概率神经网络模型;最后,利用模型参数,通过将指标分为静态基础指标和动态可变指标,前者直接输入到网络中 ...

Conservation Biology, EarlyView.Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...
