辽西朝阳盆地位于燕山构造带东段,属于松辽外围中生代的断陷盆地,勘探认识程度不高。前人研究认为,朝阳盆地下白垩统九佛堂组为湖相沉积,而忽略了火山事件对于湖盆沉积的重要影响。对此笔者通过区域地质资料调查、钻井岩心描述、岩心薄片资料观察以及分析测试资料等手段,在火山碎屑岩分类基础上,根据火山碎屑含量划分出沉积火山碎屑岩以及火山碎屑沉积岩,并结合粒度、组分、沉积构造等特征细分出11种岩相类型以及9种岩相组合,进而提出火山碎屑流、火山异重流、火山灰异轻流、热液侵入和微生物诱导5种成因机制。结合钻井岩心观察识别出火山沉积序列及沉积特征,建立了朝阳盆地九佛堂组火山湖泊沉积模式,为研究区油气资源的勘探开发提供理论依据。研究发现,火山物质对湖盆内有机质富集起到积极的影响。朝阳盆地九佛堂组烃源岩地化测试显示:含有火山细粒物质参与沉积的样品有机质丰度指标更好,有机质更富集。由于燕山构造带内其他盆地同样具有相似的火山活动地质背景,研究结果也为这些地区沉积学及油气资源研究起到良好的对比参照作用。

“中文+职业技能”教育是国际中文教育和职业教育深度融合的特色教育模式,该模式精准对接中文学习新需求,为发展国际中文教育提供了新思路。近年来,共建“一带一路”倡议得到东盟国家的高度重视和积极响应,中国—东盟命运共同体建设走深走实,东盟已有8个国家将中文纳入国民教育体系,国际中文教育经历着重大转型,孔子学院也乘着职业教育走出去的东风实现了内涵式发展。“中文+职业技能”教育还存在一些值得注意的问题,如标准体系不够完善、东盟国家对国际中文教育认知存在偏差、与英语培训项目产生实际竞争等,这些在一定程度上影响着“中文+职业技能”教育高质量发展。通过运用SWOT分析模型分析当前东盟“中文+职业技能”教育面临的内部优势和机遇、外部劣势和威胁,进而探索东盟“中文+职业技能”教育高质量发展对策。

Journal of Iron and Steel Research International 2013年第10期20卷 23-27页

作者： CUI Li SHI Quan-qiang liu xiang-hua HU xian-lei Aviation Industry Corporation of China Shenyang Aircraft Corporation Institute of Metal Research Chinese Academy of Sciences State Key Laboratory of Rolling and Automation Northeastern University

Roller leveling process of longitudinal profile （LP） plate is hardly studied because plate thickness changes. Deformation characteristics and residual curvature during LP plate leveling process were investigated based on curva ture integral by elastic plastic differences. It was found that entry intermesh section is reduced with increasing thick- ness and entry intermesh should be from 0.7 to 1.1 mm for LP plate with 42/54 mm in thickness. In order to get satisfactory flatness along longitudinal direction, small entry intermesh should be selected and exit intermesh should be 0 ram. In addition, thickness section for I.P plate which can be leveled by 11 roller leveler is from 24 to 60 mm. Finally, there is an intermesh schedule that could level LP plate with initial curvature less than elastic limit curvature.

主动脉夹层是心血管导致死亡最常见的疾病,病情危急,进展快。主要发病因素包括细胞组学因素及临床疾病因素,但导致其致病的分子机制尚不清楚。近年来,随着分子生物学的发展,由于对主动脉细胞和分子生物学的了解,越来越多的研究更倾向于对主动脉夹层的分子机制展开。主动脉壁中层细胞外基质蛋白构成的异常,细胞外基质的破坏,打破了主动脉壁的平衡机制,导致主动脉生理性变化,进而引起主动脉夹层的形成。了解主动脉夹层形成的蛋白分子机制,以达到通过人为干预的手段影响主动脉夹层的形成及进展。本综述主要阐述主动脉夹层的蛋白分子机制研究进展。

华北克拉通保存有与Columbia超大陆裂解相关的中元古代岩浆记录。本文综述了华北克拉通中元古代A型花岗岩的时空分布、岩石学和地球化学等特征,讨论了各期次A型花岗岩的成因及构造背景,论述了其对华北克拉通中元古代裂解事件的指示意义。华北克拉通主要发育4期A型花岗岩:1)~1.78 Ga A型花岗岩主要分布于南缘熊耳裂陷槽和晋陕地区;2)~1.70 Ga A型花岗岩主要分布于北缘渣尔泰—白云鄂博和燕辽裂陷槽;3)~1.60 Ga A型花岗岩主要分布于南缘熊耳裂陷槽;4)~1.32 Ga A型花岗岩主要分布于北缘渣尔泰—白云鄂博和燕辽裂陷槽。这4期A型花岗岩均来源于地壳物质的部分熔融,可能与同期伸展作用导致岩浆底侵提供热源有关。整体具有造山后伸展到陆内裂谷环境的演化序列,且存在明显的时空差异。华北克拉通中元古代A型花岗岩记录了4期主要的裂解事件,为华北克拉通参与了Columbia超大陆裂解提供了依据。

Using the effective-field theory we studied the magnetic properties of a spin-1/2 Ising supedattice, which consist of three different ferromagnet materials. The magnetic behavior of this superlattice is examined. The critical temperature and the compensation temprature of the system are studied as a function of the exchange interactions between the nearest-neiboring spins across the interface and in the intraface. Temperature dependence of magenetizations is also given.
