, 1990 目前，国内外使用较广泛的两系统是Munsell色序系统和NCS色系统。本文在色序系统理论的基础上，根据对这两种系统所进行的心理物理实验，在概念和结构上对这两种系统进行了对比分析。分析结果表明，Munsell色序系统和NCS系统各有优缺点，主要表现在Munsell系统的概念和结构比NCS系统更易于接受，而NCS的色调标示方式则优于Munsell系统，因此在色调判读方面，NCS系统表现出较高的准确度。误差分析的结论与国外同类实验的结论基本相同 ...

, 2009 矿业城市面临着严峻的群体性贫困、集体性失业和人居环境恶劣等社会问题,具有明显的脆弱性特征。在对社会系统脆弱性内涵进行界定的基础上,以阜新市5个辖区作为研究单元,选取资源型产业从业人员比重和城镇登记失业率为敏感性分析指标,从经济水平、教育水平、生活质量、社会保障等方面选取应对能力指标,构建了脆弱性评估模型,并对阜新市社会系统脆弱性程度进行了定量评估。结果表明,2005年阜新市社会系统呈现中等脆弱,但各辖区社会脆弱性差异较大。其中,社会脆弱性指数最大的是太平区,其次是新邱区 ...
