Renmin Zhujiang为科学评估新兴江一级支流廻龙河的健康状况，分析其生态保护与管理的关键问题，为南方中小河流生态修复、长效管理流域可持续发展提供理论与实践依据，以河湖健康评价为核心技术手段，构建了包含“盆”“水”、生物及社会服务功能4个准则层、共计11项指标的评价体系，系统性地评估了廻龙河的健康状态。评价结果显示：廻龙河健康评估指标综合赋分为68.37分，为Ⅲ类河湖（亚健康状态）。“盆”准则层赋分为64.85分，“水”准则层赋分为75.76分，生物准则层赋分为66.40分，社会服务功能准则层赋分为64.65分 ...

Gaoya dianqi, 2007 根据目前国内外高压断路器的检测现状,以及高压断路器状态评估方法,应用突变理论,对高压断路器的复杂系统进行多层目标分解,建立事故潜势数学表达式,来反映故障发生的本质特征和机理,对断路器状态进行模糊综合分析与评判,为高压断路器的运行状况综合评价提出了一种新思路。
