马克思恩格斯对未来社会设想与当今实践差距探析

马恩关于未来社会设想与当今社会主义实践出现了巨大的反差，对此，我们既要坚持马恩社会主义学说的科学性，又要随着时代条件的变化，在实践中不断丰富和发展马克思主义，经济文化比较落后的国家，在跨越“卡夫丁峡谷”之后，必须大胆吸收利用资本主义一切对我有用的先进成果，在经济文化比较落后的国家建设社会主义，首要的根本任务是发展生产力，要解决落后的生产力与先进关系之间的矛盾，必须通过不断的改革以解决生产力，促进生产力的迅速发展。     

西部民族地区社区教育经费投入现状研究 ——基于公共财政视角

《中国教育现代化2035》明确提出,教育向社区开放,政府投入、社会捐赠、学习者合理分担是社区教育经费来源的主渠道,政府投入列在首位,然而西部民族地区政府投入不足,不能很好地满足社区教育发展的需求.通过分析西部民族地区社区教育政府投入现状,提出"中央与地方财政事权和支出责任划分,建立科学稳定的经费核拨下达制度""将社区教育经费支出纳入政府部门预决算""优化教育经费内部结构""指明社区教育责任和实施主体"等发展路径,助力社区教育在西部民族地区均衡发展.     

促进城市旅游发展的商业行为

商业与旅游业具有集散客源的共同特征，处于基础与发展、物质与精神的不同层次，存在着相互依存、互促互动的关系。文章重点阐述了商业对城市旅游业兴起及发展的贡献作用，指出加快城市旅游业的发展，必须做好商业基础工作；大力发展商业一条街，创建商业会展品牌，加大商业网点建设，举办商场购物节。此外，大中城市应当有计划地形成中央商务区，构成商旅结合的集成效应。

Silicon＇s organic pool and biological cycle in moso bamboo community of Wuyishan Biosphere Reserve

Biomineralization of Si by plants into phytolith formation and precipitation of Si into clays during weathering are two important processes of silicon’s biogeochemical cycle. As a silicon-accumulating plant, the widely distributed and woody Phyllostachys heterocycla var. pubescens (moso bamboo) contributes to storing silicon by biomineralization and, thus, prevents eutrophication of nearby waterbodies through silicon’s erosion of soil particles. A study on the organic pool and biological cycle of silicon (Si) of the moso bamboo community was conducted in Wuyishan Biosphere Reserve, China. The results showed that: (1) the standing crop of the moso bamboo community was 13355.4 g/m², of which 53.61%, 45.82% and 0.56% are represented by the aboveground and belowground parts of moso bamboos, and the understory plants, respectively; (2) the annual net primary production of the community was 2887.1 g/(m²·a), among which the aboveground part, belowground part, litterfalls, and other fractions, accounted for 55.86%, 35.30%, 4.50% and 4.34%, respectively; (3) silicon concentration in stem, branch, leaf, base of stem, root, whip of bamboos, and other plants was 0.15%, 0.79%, 3.10%, 4.40%, 7.32%, 1.52% and 1.01%, respectively; (4) the total Si accumulated in the standing crop of moso bamboo community was 448.91 g/m², with 99.83% of Si of the total community stored in moso bamboo populations; (5) within moso bamboo community, the annual uptake, retention, and return of Si were 95.75, 68.43, 27.32 g/(m²·a), respectively; (6) the turnover time of Si, which is the time an average atom of Si remains in the soil before it is recycled into the trees or shrubs, was 16.4 years; (7) the enrichment ratio of Si in the moso bamboo community, which is the ratio of the mean concentration of nutrients in the net primary production to the mean concentration of nutrients in the biomass of a community, was 0.64; and lastly, (8) moso bamboo plants stored about 1.26×10¹⁰ kg of silicon in the organic pool made up by the moso bamboo forests in the subtropical area of China.

Assessment of semi-empirical mass transfer correlations for pervaporation treatment of wastewater contaminated with chlorinated hydrocarbons

INTRODUCTION Chlorinated hydrocarbons, a class of widely used dry-cleaning liquids, industrial organic solvents, and degreasers, increasingly find their way into drinking water sources, thus posing a very serious health and environmental problem (Love and Eliers, 1982). These organic solvents are known for their stability in the environment and cancer-causing po- tency and cannot be effectively and economically eliminated by current conventional treatment tech- nologies. One of the few av…
