中国海事调查体制

针对中国海事调查现状,从海事调查立法、调查机构和调查官三方面研究中国海事调查体制.在比较美国、英国及其他国家海事调查体制基础上,分析制约中国海事调查发展的主要问题,指出独立海事调查的发展趋势,提出完善和推动海事调查进一步发展的建议,强调了值得中国借鉴的战略利益.     

Lithostratigraphy and faunal aspects of marine Jurassic rocks in Thailand

Thai marine Jurassic rocks are well exposed in the Mae Sot, Umphang, and Phop Phra areas, less extensively near Mae Hong Son, Kanchanaburi, Chumphon, Nakhon Si Thammarat and Krabi. Generally they rest unconformably on Permian and Triassic, and are overlain by Quaternary strata. Fourteen lithostratigraphic units are defined (in ascending order): Pa Lan, Mai Hung, Kong Mu formations of the Huai Pong Group-Mae Hong Son area; Khun Huai, Doi Yot, Pha De formations of the Hua Fai Group-Mae Sot area; Klo Tho, Ta Sue Kho, Pu Khloe Khi, Lu Kloc Tu formations of the Umphang Group-Umphang area; and Khlong Min Formation-Chumphon, Nakhon Si Thammarat, and Krabi areas. Dominant widespread mudstones, siltstones and sandstones; limestones are confined to the Mae Sot, Phob Phra, Umphang, Kanchanaburi and Mae Hong Son areas; marls are found only in Mae Sot. Sequences are approximately 900 m thick (Mae Sot), 450 m thick (Umphang) and thinner elsewhere, especially the south. Based on ammonites, brackish to marine bivalves, and foraminifera, the beds are dated mainly as ToarcianEarly Bajocian.     

大气环境承载力是山西经济发展的硬约束

文章通过大气环境承载力评价模型，对历年来山西大气环境承载力的发展态势进行评价，并对2003年11个地市的大气环境承载力现状进行评述；根据预测模型，采用警告型预测和目标导向型预测对山西省和11个地市大气环境承载力进行预测，提出污染物浓度达到环境保护要求的排污系数和应有的递减速率以及11个地市的污染物排放量应达到的基准。     

Development of an Accurate Urban Modeling System Using CAD/GIS Data for Atmosphere Environmental Simulation

This paper presents an urban modeling system using CAD/GIS data for atmosphere environmental simulation, such as wind flow and contaminant spread in urban area. The CAD data is used for the shape modeling for the high-storied buildings and civil structures with complicated shape since the data for that is not included in the 3D-GIS data accurately. The unstructured mesh based on the tetrahedron element is employed in order to express the urban structures with complicated shape accurately. It is difficult to understand the quality of shape model and mesh by the conventional visualization technique. In this paper, the stereoscopic visualization using virtual reality (VR) technology is employed for the verification of the quality of shape model and mesh. The present system is applied to the atmosphere environmental simulation in urban area and is shown to be an useful planning and design tool to investigate the atmosphere environmental problem.     

气体比热容比测定实验中的压强处理研究

通过使用气体比热容比测定仪,对气体比热容比测定实验教学中压强p存在的两种处理方法进行了探讨,说明了压强p应采用大气压强与4mg/πd2 之和的理由,并提供了可用于计算大气压修正值表的程序,从而解决了使用DYM1型动槽水银气压表时查大气压修正值的问题。     

可控气氛热处理中碳势的测量与控制研究

系统地研究了可控气氛在热处理中的碳势,通过对炉气碳势的影响因素、碳势的测量方法、碳势的控制原理与方法的分析与综合,对影响炉气碳势的不利因素进行了剖析。同时针对这些不利因素,对炉气碳势的测量与控制方法进行了研究,提出了目前最佳的渗碳工艺方法,即在整个渗碳过程中对碳势进行台阶式控制的方法。     

论丰子恺散文的艺术特质

丰子恺散呈现为一种闲话语境，本潜含一种与读对话的可能性，拉近了作与读之间的距离。且又具有“淡如菊”的特点，即朴实平淡、自然无饰的语言以及清澄深远的艺术意境。     

优化公体乒乓球教学心理环境的实验性研究

运用文献资料法、实验研究法和数理统计等研究方法，对现行高校公共体育乒乓球选项课进行了合理的优化与改良，并创设出一套最佳教学心理学习环境。经过为期一年的实验性研究．发现学习心理环境设置的好坏。对于学生的课堂学习积极性的调动、课堂参与意识以及教学内容掌握程度的好坏有着较为明显的影响力。而且差异极为显著。     

论张爱玲散文的出世与入世

张爱玲的散文创作成就非常突出。在动荡的时代大背景下,多种原因形成了她作品中始终挥之不去的出世的孤独漂浮感和生命的虚无幻灭感——"苍凉";同时,她的散文又以一种执着的现世精神沉浸感知着市民生活的点滴意趣,去还原人的真实本性。两者互为映衬,形成了张爱玲散文的独特风景。     

中华猕猴桃贮藏保鲜的研究

本文研究了贮藏温度、相对湿度、气调因子和内源乙烯对中华猕猴桃贮藏效果的影响.结果表明,用0.05mm厚聚乙烯袋密封贮藏中华猕猴桃,造成自发气调环境(CO_2分压3-6%,O_2分压4-9%),控制温度于0±1℃,相对湿度90-95%,贮藏寿命可达150天左右,好采率不低于90%,维生素C保存率85-90%,果实新鲜饱满、风味正常. 结果还表明,不同品系中年猕猴桃的耐藏性能差异甚大.果实采收期以控制果肉可溶性固形物含量7-8%为宜.
