The reverse flotation for desiliconization form bauxite is better than direct flotation, and the grinding before flotation affects the flotation indexes to some extend. The grinding dynamic equation of bauxite based on the data of grinding experiment of diasporic bauxite was derived. The calculated value of the equation is identical with the experiment value. Further the grinding dynamic equation of intermediate grain size range suitable for reversal flotation has also been derived. The grinding time required could be calculated when the mass fraction of intermediate size grain is maximum. The formulation of grinding dynamic equation considerably simplified the grinding experiment, optimized the grinding process. [

探索专业村镇的地域分异格局特征及其影响因素,对实施农业转型升级与乡村振兴战略具有重要参考价值。本文基于农业农村部"一村一品"示范村镇资料揭示了中国专业村镇的空间格局,运用地理探测器模型从全国和农业区尺度分析了地形特征、资源禀赋和区位条件等村域环境因素,以及市场需求和经济基础等区域环境因素对专业村镇分布的影响。研究发现:①中国专业村镇主要分布在胡焕庸线东南半壁,占83.64%,呈现中心集聚和由华北平
流域生态补偿是中国跨区域生态治理和自然区域保护的一项重要经济、社会、环境政策,涉及区域利益主体权益差异与协调、区域生态协同发展和合作模式构建等方面,是一个典型的地理学研究命题。本文将制度粘性引入到尺度政治理论中,剖析新安江流域生态补偿政府主体的博弈行为,探究不同政府主体的博弈特征和博弈机制。结果表明:中央政府、省级政府、市级政府等不同层级政府主体经历了竞争博弈、合作博弈和竞合博弈3个阶段,构建政府
6月4日,江西省高级人民法院对外公布了非法开采稀土案、长江流域非法倾倒污泥案、巨蟒峰损毁案等一批社会高度关注的环境资源典型案例.rn江西省高级人民法院副院长胡淑珠介绍
探索贫困监测评估指标体系及区域间贫困时空交互动态特征对当前中国可持续减贫研究具有重要意义。基于发展地理学视角,引入面板向量自回归(PVAR)模型并结合人类发展分析路径与SDGs全球指标框架识别影响中国贫困的致贫和减贫因素,以此测度多维贫困指数,进而采用探索性时空数据分析(ESTDA)方法揭示多维贫困的时空交互特征。结果表明:①中国当前贫困监测评估的致贫因子包括农作物受灾比和社会总抚养比,减贫因子则
今年全国两会期间,习近平总书记在看望参加全国政协会议的经济界委员时强调,要坚持用全面、辩证、长远的眼光分析当前经济形势,努力在危机中育新机、于变局中开新局.这为我们
A near-distance, nonlinear coupling relationship objectively exists between urbanization and the eco-environment. The issue of how to coordinate the relationship between them has become a global strat
脆弱性作为乡村生产空间系统的重要属性,是探讨系统易受负面影响或损害程度的有效度量、解析系统可持续发展趋势的有效途径。以重庆市为研究区,以2007—2017年为研究时段,建立乡村生产空间系统脆弱性评价指标体系和评价模型,以定量测度乡村生产空间系统脆弱性,揭示其时空分异特征,进而划分脆弱性类型并提出差异化调控策略。结果表明:①乡村生产空间系统脆弱性是系统运行状态的综合度量,包含暴露度、敏感性和适应能力
As a special outcome of urbanization, mega-towns not only play an important role in the process of socio-economic development, but also are important contributors to urbanization. Based on a spatial d
