道家“和谐”思想的现代性审视

和谐是中西哲学史上颇受关注的问题之一，亦是道家哲学思想的核心范畴之一。道家始祖老子的和谐思想在中国传统哲学思想中占有重要地位，将其与西方传统和谐思想进行对比和反思，剖析道家自然和谐型社会和谐理论，剔除其与当代社会现状之间不和谐之处，对探求与当下社会发展及人自身发展相契合的新的社会和谐思想有重要意义。     

财政政策背景下的家庭教育投资行为分析

概述了国内外对公共教育投资和家庭教育投资的研究,选择新古典经济学中的家长最优化框架来构建家庭教育投资的一般模型.在此基础上,引入了3类公共教育财政政策,即强制供给、收入补贴和专项补贴.重点考察了在这3类教育财政背景下家庭教育投资的行为,并对一般模型和这3类模型的结论做了进一步的比较分析,为教育财政政策的制定提供了一些可行建议.     

房地产开发中的户型面积优化模型研究

针对当前房地产业内开发商靠哄抬房价、囤地、囤房以谋取高额利润的不良现象,指出房地产开发商要走出误区、健康获利的唯一途径是制定科学的开发方案,而科学的开发方案依赖于优化的户型面积设计.本文从房地产开发商角度出发,提出利用熵权系数综合评价法,对备选的不同面积的户型进行综合效益评价,并在此基础上给出了以开发商总效益最大为目标的房地产户型组合优化模型,从而有助于开发商形成科学的开发方案.

A positive-temperature-coefficient electrode with thermal protection mechanism for rechargeable lithium batteries

A new positive-temperature-coefficient(PTC) material was prepared simply by blending of conductive Super P carbon black(CB) with insulating poly(methyl methacrylate)(PMMA) polymer matrix,which was empolyed as a coating layer on the aluminium foil substrate to fabricate a sandwiched Al/PTC/LiCoO2 cathode.The experimental results from cyclic voltammetry,charge-discharge measurements and impedance spectroscopy demonstrated that the PTC electrode has a normal electrochemical performance at ambient temperature,but shows an enormous increase in the resistance at the temperature range of 80?120℃.This PTC behavior greatly restrains the reaction current passing through the electrode at elevated temperatures,capable of acting as a self-actuating safety mechanism to prevent the battery from thermal runaway.     

货价呈现布朗运动规律的海陆仓融资收支利率优化研究

考虑了由船公司向中小进口商融资以支付货款的海陆仓融资模式,建立了货物价格呈现布朗运动规律的海陆仓融资收入利率和支出利率优化的模型.该模型以船公司为领导者,进口商为跟随者,银行为合作伙伴,研究了船公司如何制定出对自己最有利的收入利率,然后根据风险与收益对等的原则来决策船公司的支出利率.最后,运用算例验证了模型的有效性.     

淮北市洪庄村采煤塌陷区生态农业系统优化研究

煤炭开采造成了土地塌陷,对煤炭产地的社会、经济和环境造成了不利影响,生态农业复垦技术是治理采煤塌陷区的有效措施.淮北市洪庄村是典型的采煤塌陷区,洪庄村生态农业模式是以沼气为纽带的生态农业,把种植业、养殖业、旅游业和加工业连为一体,通过对系统的空间结构、时间结构和营养结构的优化,高效利用太阳能和生物质能,物质良性循环,使废弃物资源化、无害化,经济发展和生态保护相互促进,取得了良好的综合效益.洪庄村连续12年是中国土地复垦示范区和中国农业旅游示范区,可以为其他的采煤塌陷区发展生态农业提供借鉴.     

太白山国家森林公园景区接待能力研究

旅游景区接待能力的高低直接影响着游客在旅游地的旅游活动质量,同时反映着一个旅游景区的发展成熟程度。太白山国家森林公园自建立以来,现在已发展成为一个相对完善的旅游景区。针对该景区的住宿、交通、餐饮、购物、接待能力等方面做了调查、整理和分析,并通过研究分析相关数据后,提出相应的建议。     

变——圜道哲学观的内核

圜道即循环之道.圜道观即循环论,其认为宇宙及宇宙间万物都永恒地循着周而复始的环周运动:发生、发展、消亡.它的展开论述始见于<吕氏春秋·圜道篇>,从先秦至今,圜道思想是中国传统文化中最根本的观念形态之一,中国传统哲学一直把"循环往复"理解为圜道观的最大特点,殊不知,"变"才是其真正的思想核心.     

Biosorption and biodegradation of polycyclic aromatic hydrocarbons by Phanerochaete chrysosporium in aqueous solution

Biosorption and biodegradation of phenanthrene and pyrene by live and heat-killed Phanerochaete chrysosporium are investigated to elucidate the bio-dissipation mechanisms of polycyclic aromatic hydrocarbons(PAHs) in aqueous solution and its regulating factors.The effects of nutrient conditions(carbon source and nitrogen source concentrations),the co-existing Cu 2+,and repeated-batch feed of PAHs on the biosorption and biodegradation are systematically studied.The removal of PAHs by dead bodies of P.chrysosporium is attributed to biosorption only,and the respective partition coefficients of phenanthrene and pyrene are 4040 and 17500 L/kg.Both biosorption and biodegradation contribute to the dissipation of PAHs by live P.chrysosporium in water.After a 3-d incubation,the removal percentage via biosorption are 19.71% and 52.21% for phenanthrene and pyrene,respectively.With the increase of the incubation time(3 40 d),biodegradation gradually increases from 20.40% to 60.62% for phenanthrene,and from 15.55% to 49.21% for pyrene.Correspondingly,the stored-PAHs in the fungal bodies decrease.Under the carbon-rich and nitrogen-limit nutrient conditions,the removal efficiency and biodegradation of phenanthrene and pyrene are significantly promoted,i.e.99.55% and 92.77% for phenanthrene,and 99.47% and 83.97% for pyrene after a 60-d incubation.This phenomenon is ascribed to enhanced-biosorption due to the increase of fungal biomass under carbon-rich condition,and to stimulated-biodegradation under nitrogen-limit condition.For the repeated-batch feed of phenanthrene,the pollutant is continuously removed by live P.chrysosporium,and the contribution of biodegradation is enhanced with the repeated cycles.After 3 cycles,the biodegradation percentage is up to 90% with each cycle of a 6-d incubation.
