论毛泽东的农业现代化思想

新中国成立后，毛泽东十分关注中国农业经济的发展。为此，他积极探索，形成了丰富的农业现代化思想：农业是国民经济的基础；发展农业科学技术、提高农民素质和领导干部科学管理水平、大力发展农村商品经济是实现农业现代化的必要条件；“先合作化，后机械化”是实现农业现代化的道路。这些思想，对我们今天农业的发展和农业现代化建设具有现实意义。     

纪念中华人民共和国建国50周年：邓小平对毛泽东经济思想的继承和发展

探索中国式的社会主义道路，实现中国的社会主义现代化，是毛泽东邓小平两代领导人的宏伟愿望。毛泽东经济思想是邓小平经济思想直接的理论渊源．邓小平经济思想则是毛泽东经济思想的继承和发展，它们之间存在着不可分割的一脉相承关系，是继承与突破、坚持与发展的结合。     

毛泽东科学决策特色探析

毛泽东作为无产阶级革命家、政治家，在长期的革命和建设实践中，进行了一系列重大而正确的决策，形成了一套独具特色的决策理论和思想，这些理论和思想是当代决策科学的精华。他好学深思，注重调查研究；在实施决策方面，运用矛盾原理创造出综合方法；在决策价值选择方面，以人民群众利益为出发点和落脚点；在决策程序上，运用择优的办法把眼前利益与长远利益、局部利益与全局利益结合起来；在决策的思想路线上，坚持实事求是，保证决策科学性。毛泽东科学决策的理论和思想是我党一笔宝贵的精神财富。     

浅析毛泽东现代化思想的内涵及特点

毛泽东的现代化思想涉及到经济、政治、文化等各个层面,规划了四个现代化的宏伟蓝图,构建了具有中国特色的社会主义民主制度,提出了建设科学的、民族的、大众的文化和“两为”方向与“双百”方针。从总体上看,毛泽东的现代化思想不仅是坚持社会主义发展方向与社会全面发展的现代化,而且还是注重发展生产力、实行改革开放并坚持走自己道路的现代化。     

论毛泽东教育思想与中国教育梦

毛泽东一贯高度重视教育，他的教育思想作为毛泽东思想的重要组成部分，不仅内容丰富，而且富有特色。今天，我们纪念毛泽东的最好方式，就是坚持毛泽东一贯倡导的群众路线、实践本位、全面发展的主张，把干部群众思想统一到实现“中国梦”的方向，开创世纪教育的新纪元。     

不屈的意志理性的光辉--1949至1965年毛泽东对苏外交坚持独立自主原则的哲学思考

独立自主是我国外交政策的根本原则，毛泽东的对苏外交是坚持独立自主原则的光辉典范。他一贯擅长的哲学思维使他能够在更深邃、更广阔的视野中，观察和分析中苏关系演变的规律，并据此制定出符合实情的外交政策和策略，坚定了独立自主的决心和信心，也使他的对苏外交思想和实践带有浓厚的哲理色彩和光辉。具体表现在：以斗争求团结的矛盾论方法；关于学习苏联、赶超苏联的辩证思考；以唯物史观为指导，增强对苏外交的群众基础与实力地位；依据意识能动性原理，重视发挥思想和精神的作用     

论毛泽东调查研究思想中的党建思想

毛泽东调查研究思想发端于革命年代，是坚持辩证唯物主义、反对唯心主义的产物，在社会主义现代化建设新时期，调查研究依然对坚持和完善党的思想路线和党的作风有着举足轻重的作用，也是加强党先进性建设和党执政能力建设的重要途径。     

浅析毛泽东的现代化思想

毛泽东现代化思想是建立在对中国现代化历史主题的正确认识基础上的，有一定的目标体系和实现途径的统一体，认识毛泽东的现代化思想对今天仍有重要启示。     

毛泽东对中国式现代化模式的贡献

毛泽东关于中国现代化的思想十分丰富，他的现代模式既不同于西方，也不同于苏联，而是符合中国国情的中国模式，这为之后的具有中国特色的社会主义现代化模式打下了基础，为中国的现代化建设和出了巨大贡献。     

邓小平政党制度思想研究

邓小平在马克思、列宁、毛泽东政党制度思想的基础上作了进一步的发展，指出了比较完整的政党制度思想。其中主要包括三个方面的内容；坚持中国共产党领导下的多党合作制度，绝不能搞西方的多党制；坚持党的领导，改善党的领导，加强党的自身建设：树立党中央的权威，反对形式主义和官僚主义。     

Relationships of Aegilops tauschii revealed by DNA fingerprints: the evidence for agriculture exchange between China and the West

Genetic diversity and relationships of wild goat grass (Aegilops tauschii Cosson) from Iran and Xinjiang, west China, as well as its weedy type from the Yellow River region of Shaanxi and Henan provinces in China were analyzed by simple sequence repeat (SSR) fingerprinting. A high level of genetic diversity in Aegilops tauschii accessions from Iran was observed, and the richness of genetic diversity was followed by accessions from Shaanxi, Henan, and Xinjiang. The weedy type of Aegilops tauschii showed a close genetic relationship with the wild type from different regions in Iran. The results indicated that the weedy Aegilops tauschii found in the Yellow River region was most likely introduced from Iran—the diversity center of Aegilops tauschii. The weedy Aegilops tauschii populations found in the Yellow River region may be brought into the central part of China as a weed species together with common wheat (Triticum aestivum L.) from the west during various periods of time in history. This finding has provided strong evidence for the introduction of common wheat from the West into China via the Silk Road, and also demonstrated the important role of the Silk Road in the exchange of agriculture and other relevant technologies between China and the West.     

Molecular fossils and oil-source rock correlations in Tarim Basin, NW China

The distribution of "molecular fossils" (bio-markers) of steroid compounds in extracts from some spe-cific geologic age in the Tarim Basin have been analyzed andare used as the fingerprints for the oil-source rock correla-tion. Having been affected by maturation, migration, phasefractionation and biodegradation, not any molecular fossilsrelated to source and environment can be used as the finger-prints for oil-source rock correlation. Some special bio-markers widely existed in the extracts from Cambrian andOrdovician rocks in the Tarim Basin and showed obviousdifference in each stratum, including dinosteranes (C₃₀),4-methyl-24-ethyl-cholestanes (C₃₀) and their aromatizedsteroids, C₂₄-norcholestanes and C₂₈ steranes originated fromdinoflagellates and diatom. Few oils such as the heavy oildrilled in the Cambrian reservoir from Tadong 2 well (TD2)correlated well with the extracts from the Cambrian. Theamazing similarity of the relative contents of these com-pounds between the marine oils produced in Tazhong andTabei uplifts and the extracts from the Upper Ordoviciansuggests that the Middle-Upper Ordovician is the very likelymain source for the marine oils.     

广西合浦榕根山小型海草床的群落演替及其保护和修复研究

2001～2011年现场调查和监测广西合浦沙田镇附近的榕根山海草床,研究小型海草床的群落演替及其保护和修复.结果发现,从2001年到2005年,榕根山海草床的面积从13.3 hm2增加到17.1 hm2,但是2006年以后海草床的面积开始减少,至2011年面积已减少到不足1 hm2.海草的群落也由矮大叶藻(Zostera japonica)单一优势种群落演替为贝壳喜盐草(Halophila beccarii)优势种群落,引起海草的盖度、生物量和茎节密度明显变化.榕根山海草床衰退主要是由于海水水质变化、互花米草(Spartina alterniflora)入侵,以及鸭子放养引起,保护和修复榕根山海草床要控制海草床周边互花米草扩散和整治岸边的畜禽养殖及污水排放,同时还要加强对海草床的监测和保护及修复研究,探索海草与互花米草的竞争机制及互花米草控制方法,为小型海草床的保护和修复提供理论和技术支持.     

Investigation of gas concentration cell based on LiSiPO electrolyte and Li2CO3, Au electrode

Solid lithium ion conducting electrochemical cells using LiSiPO as solid electrolyte and Li₂CO₃ mixed with Au as electrodes were prepared and employed as chemical sensors for the detection of CO₂ gas. The EMF of the cell depends on the concentration of CO₂ in air according to the partial pressure dependence of Nernst’s law in the investigated range from 100 to 2000 ppm over the temperature range from 473 K to 673 K.     

Coesite inclusions in zircon from gneisses identified by laser Raman microspectrometer in ultrahigh pressure zone of Dabie Mountains, China

The mineral inclusions in zircon from gneisses in ultra-high pressure (UHP) zone of the Dabie Mountains were identified by using a laser Raman microspectrometer. Coesite occurs as inclusions in zircons from all types of gneiss. Other important minerals, such as jadeite, omphacite, aragonite, barite, and anhydrite were also found as inclusion minerals. These discoveries indicate that (ⅰ) gneissic country rocks had metamorphosed at the same time as the enclosed eclogites; and (ⅱ) SO₄^-2-bearing fluids were present in the UHP metamorphic process, which is manifested by occurrence of barite and anhydrite coexisting with coesite.     

Numerical simulations of nutrient transport changes in Honghu Lake Basin,Jianghan Plain

Nutrients transported from catchments are one of the most important sources for lake eutrophication. In this study, the Honghu Lake Basin, located at the middle reaches of the Yangtze River, was chosen as the study area, and the watershed hydrological distribution model SWAT （Soil Water Assessment Tool） was applied to evaluate the trajectory of watershed nutrient transportation over time. Based on the analysis of driving factors, three experiments corresponding to natural, traditional and modern agriculture processes respectively were designed to evaluate the changes of nutrient inputs from catchments under the three environments. The simulation results showed that there were variations in nutrient production and changes in the range and rate. For three periods of the experiments, TN concentrations have changed as 0.12→0.31→1.15 mg/L, and production as 420→1650→6522 T/a; while TP concentrations changed as 0.018→0.057→0.117 mg/L, and production as 78→303→665 T/a. The nutrient transportation experienced slowly long-term increases during 1840--1950, then showed a relatively rapid increase during the period of 1950-1980s and the period from 1980 to early 1990s, with increasing rate of 1.4% and 2.4% respectively. And from the later 1990s to now, an obviously increasing trend with 15% increasing rate occurred. The effect from human activities on the watershed nutrient transportation increased rapidly, and had become a dominant factor in changes of the nutrient transportation.

秦俑博物馆室内气溶胶的演化特征及影响因素

 分析了2013 年秦俑博物馆(秦俑馆)1 号坑遗址保护展示厅的室内空气质量, 包括微气候条件、气溶胶质量浓度及化学组成的冬、夏季特征, 并通过探讨其在1989 至2013 年间的演化, 评价博物馆的旅游规划和环境改善政策对文物保存大气环境的长期影响。自20 世纪90 年代开始, 秦俑馆内一系列环境措施的实施和旅游条件的建设, 对秦俑馆室内的气溶胶及其组成产生了显著的影响。其中, 夏季室内总悬浮颗粒物(TSP)的质量浓度由1994 年的540.0 μg·m^-3降低至2004 年的172.4 μg·m^-3, 冬季TSP 的质量浓度由1994 年的380.0 μg·m^-3降低至2005 年的312.5 μg·m^-3。夏季PM_2.5的质量浓度由2004 的108.4 μg·m^-3降低至2013 的65.7 μg·m^-3, 冬季PM_2.5的质量浓度由2005 的242.3 μg·m^-3降低至2013 的98.6 μg·m^-3。尽管如此, 秦俑馆内的文物依然面临气溶胶酸性组分的长期威胁。
