化学品环境安全管理的国际格局分析研究

化学品的环境安全管理涉及到公共安全、环境保护、经济发展等多个领域。在分析欧盟化学品注册、评估、许可制度的国际影响的基础上,从POPs公约、化学分类和标识系统（GHS）以及国际化学品管理战略步骤（SAICM）的提出和推广可以看出,化学品环境安全管理正呈现出国家共治、彼此影响的全球治理格局。分析国际格局对完善和健全我国化学品环境安全管理体制有基础性作用和方向性指导意义。

Equipment Maintenance Material Demand Forecasting Based on Gray-Markov Model

Maintenance material reserves must keep an appropriate scale,in order to meet the possible demand of support objectives.According to the sequence of maintenance material consumption,this paper establishes a Gray-Markov forecasting model by combining Gray system theory and Markov model. Few data are needed in the proposed Gray-Markov forecasting model which has high prediction precision by involving small parameters. The performance of Gray-Markov forecasting model was demonstrated using practical application and the model was proved to be a valid and accurate forecasting method. This Gray-Markov forecasting model can provide reference for making material demand plan and determining maintenance material reserves.
