高颐阙残损阙檐的修复技术

高颐阙是东汉晚期的红色砂岩的建筑物。位于四川省雅安市。阙檐东面残缺.导致日晒雨淋加剧,苔藓丛生,从而引起严重风化。为此,对残损阙檐进行了修复。根据高颐阙的结构.雅安市的气候特征及阙石的化学组成和物理性质.讨论了薄片检查和 X 衍射分析的结果、修复残缺阙檐的理论基础以及计算、修复的程序和效果。     

Multiphase flow simulation through porous media with explicitly resolved fractures

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the P_N+1DG‐P_NDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated.     

《寿昌乘》辑本辑佚之考察

《寿昌乘》系南宋晚期寿昌军(今湖北鄂州市)方志,大致散佚于明清之际,清末文廷式自《永乐大典》辑出,后柯逢时刊刻文氏辑本,是为武昌柯氏息园刻本,此即"宋元方志丛刊"影印之底本。《寿昌乘》是唯一存世的宋代湖北方志,所载内容,如寿昌军沿革、军制与军学等,均仅见于此志,史料价值弥足珍贵。然而,该志的辑佚却未尽如人意,主要表现为漏辑、文字舛误与体例混乱三方面。翻检《永乐大典》残卷,可新辑出《寿昌乘》佚文四条,且可纠正文字传抄之误;分析辑本纲目间的层级与隶属关系,则能恢复此志体例原貌。     

Biomechanics of coaching maximal instep soccer kick for practitioners

Kicking in soccer has been the subject of scientific research for more than 40 years yet review articles summarizing the biomechanical fundamentals of kick optimization as a guide to coaching are scarcely to be found. The current review article aims to bridge the gap between scientific research into the maximal instep kick (including studies employing 3D motion capture and full-body biomechanical modelling) and the application of such research in coaching. It does so by supplying a scientifically founded, coaching-friendly article explaining identifiable characteristics and motor control sequencing that define this skill. Relevant biomechanical factors are identified in a way that should help coaches better develop training programmes and, at the same time, foster better understanding of the skill among athletes. Such information will contribute to both accelerated skill acquisition and, by concomitant gains in skill efficiency, the development of programmes that minimize risk of injury to athletes during training.

焦竑的学术特点与史学成就

焦竑字弱侯,号澹园,又号漪园,谥文端、文宪,江宁(今南京)人,是晚明最负盛名的学者之一,尤其精于史学.明代史学风气至嘉、万时期丕变,由空疏转向谨严.其中功绩,王世贞之外,则首推焦竑.在焦竑传世的三十余种著作中,史学著作计有《献征录》120卷、《熙朝名臣实录》27卷、《逊国忠节录》4卷、《国史经籍志》6卷、《玉堂丛语》8卷、《皇明人物考》6卷、《京学志》8卷、《词林历官表》3卷等,此外尚有汇录大量考史笔记的《焦氏笔乘》6卷和《续笔乘》8卷等,是明代整个学术发展中非常有影响的人物①.     

赤水河疏浚与川盐(仁岸)入黔

张广泗上疏朝廷,于乾隆十年十一月至十一年闰三月,首浚赤水河,疏通68处险滩,使川盐由四川合江经赤水河到仁岸茅台村,运输路程大大缩短,盐价渐平,对黔人"斗米斤盐"之负担有所减轻,经济效益十分明显.文中还对赤水河源流及遵义知府陈玉(殿)是否参与赤水河疏浚、吴登举之死等问题,均有论述与考辨.

地方志与城市化推进中的文化记忆抢救工程

在今后相当长的一个时期,地方志工作需要致力于“文化记忆抢救工程”这样一个领域,这个工作是各地建设文化大省的重要内容。在我国城市化高潮来临的情况下,建设与保护是一对共生的矛盾,“文化记忆抢救工程”的急迫性在某种程度上就是要与社会经济发展抢速度。
