政策推动下环保产业上市公司综合绩效的实证分析——因子分析与聚类分析的综合研究
环保产业 综合绩效 因子分析 聚类分析
2018/11/21
本文采用因子分析与聚类分析的方法对我国环保产业上市公司2008 ~ 2015年的财务数据展开实证分析。研究发现：环保产业整体绩效一般，但稳中趋好的发展态势明显；偿债能力与盈利能力是环保产业公司绩效最重要的影响因素；绩效评价是综合评价体系，现金流量能力、营运能力、成长能力对企业综合绩效同样重要；综合绩效排名前十位的公司占比最多的是处于高成长期的污水处理与自来水升级、生活垃圾处理行业；公因子中，偿债能...
传感器在农业生产中的应用及其耐低温研究
农业 传感器 低温
2017/11/13
传感器是农业物联网中的关键环节，但高寒地区对传感器的耐受温度有较高要求，尤其是低温（-40℃）条件下测量数据的准确性及传感器的耐用性，直接影响物联网的整体调控运行。本文介绍了传感器在农业生产中的各项应用，并对农业物联网中主要的两类传感器，大气温湿度传感器和照度传感器的性能进行了-40℃耐低温测试，为农民选择传感器提供帮助。
正渗透技术研究现状及进展
正渗透膜 浓差极化 汲取液 正渗透应用
2016/11/1
作为一种新型膜处理技术，正渗透技术自20世纪50年代建立以来，在环保、能源、海水淡化等领域受到越来越广泛的关注；其经历了从实验室研究，中试实验，到少量的商业化应用，技术日臻完善.本文综合了国内外相关文献的信息，从正渗透膜制备、浓差极化、汲取液及正渗透应用等四方面对正渗透技术的研究现状及进展进行了综述，并分析了其应用过程中存在的缺陷和未来发展趋势.正渗透技术的研发虽取得了显著进展，但仍存在应用瓶颈....
