A MOUNTAIN WEASEL SPOTTED IN LHASA

<正>Four of us went to a suburb in Lhasa for an autumn outing one day in the middle of October.We drove out of the downtown area heading east and reached our destination,Caigongtang Temple.Interestingly enough,it was a result of random selection based on Google maps that led us here since we neither knew     

Human adaptation and socioeonomic change in northeast China: Results of the Fuxin Regional Survey

Northeastern China is one of the centers of early development of agriculture and sedentary life, as well as of the subsequent development of social complexity and distinct cultural attributes. While the outlines of this trajectory are clear, its important details are still elusive. Like all other regions of northern China, there is little data on the all-important transition from nomad hunter-gatherers to sedentary agriculturalists. The Fuxin Regional Survey was designed as the first step in accumulating new data and addressing the geographic and ecological contexts of these socioeconomic processes. Among the most remarkable results of this survey is the identification of early ceramics, which possibly predate the transition to agriculture. The systematic collection and analysis of stone tools was done in a way never before done in this region. Analysis of our findings, using GIS and other methods, sheds new light on the local trajectory of human adaptation in this area.     

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.     

论"五四"时期儒家道统之接续

接续是指对儒家道统在承继基础上予以新时期之创发,是接与续的统一.在承继先秦儒家道统论、宋明儒家道统论基础上,现代新儒家吸纳新鲜元素而充实之,以重构现代儒家道统论.异构是接续传统儒家道统,构建现代道统的一种方式.通过对佛学、西学的批判、比较,以求其异,以此来彰显和重构儒家道统."五四"时期,在国内思想界人文主义回归的背景下,熊十力、梁漱溟、张君劢、冯友兰通过反省传统儒学,以宋明儒家道统论为其理论渊源,通过中、印、西之比较而进行批判,分明壁垒,吸纳佛学的思辨体系或西学某些概念,以中西比较的方式凸显儒学特质之优长及其现代价值,现代新儒家试图以异构来接续儒家道统,复古有余而创发不足.     

长江中游地区楚墓中出土的青铜箭镞的锈蚀现象及锈蚀机理研究

青铜箭镞是古代制造量最大、一次性使用的兵器,与要求甚高的青铜剑和青铜礼乐器等相比,在选材和表面处理等方面有很大的不同,其锈蚀过程最能反映材料在经过数千年后所产生变化。长江中下游地区环境潮湿,埋藏条件复杂,本研究利用扫描电子显微镜（SEM）、能谱仪（EDS）、X-射线衍射仪（XRD）、显微硬度等分析测试技术,从材料科学的角度对长江中游地区战国晚期古墓中出土的青铜箭镞的锈蚀现象和锈蚀机理进行了全面的研究和分析,以期为古代青铜器的保护提供更准确的信息和资料。结果表明,青铜箭镞的组织结构可分为完全矿化层、过渡层和心部原始材料等三个特征层,不同特征层具有不同的显微组织、化学成分、致密性,以及显微硬度等;并沿横截面观察和分析了锈蚀层中的微裂纹的性质和产生原因,即,平行于表面的裂纹是由矿化层氧化物膨胀引起的剥离开裂,其进一步发展将形成“粉状锈”,而垂直于表面呈放射状的裂纹是当圆柱形箭镞杆膨胀时,矿化层的塑性差,抗变形能力低而产生的开裂;锈蚀机理研究认为青铜器的锈蚀过程是环境中杂质元素通过过渡层沿界面能较高的α固溶体和（α＋δ）共析体晶界或孔隙等缺陷逐步向内部扩散的结果。     

商前期青铜斝的制模工艺初步研究

制模是青铜铸造工艺的第一道工序,也是关键工艺之一,其重要性不言而喻。而文献记载的缺乏,考古实物资料的限制,严重影响了学界对陶模制作工艺的认识。近年来,我们通过对大量青铜实物的细致考察,发现大多青铜器上都有明确、整齐的范缝。为研究夏商之际的范铸技术,我们对商前期青铜斝进行了模拟制备,发现分型制模才是其制模工艺的主流,用此种工艺制模更加符合器物上的范铸特征。

Overpressure in the Malay Basin and prediction methods

Predrill overpressure prediction is important for well planning and migration modeling for prospect evaluation. The Eaton (Journal of Petroleum Technology, 24 , 1972, 929) and Bowers (SPE Drilling & Completion, 10 , 1995, 89) methods are used worldwide for postdrill overpressure prediction using sonic log and predrill overpressure prediction using seismic interval velocity. In this research, these two methods were used for overpressure prediction using 3D anisotropic prestack depth‐migrated seismic interval velocity in a field of the Malay Basin. In the shallow overpressured zone, where the mechanism of overpressure is undercompaction, the onset of overpressure was predicted reasonably well using the Eaton and Bowers methods with their standard parameters (i.e., Eaton exponent 3 and Bowers loading curve) for seismic velocity. However, in the deep overpressured zone, where fluid expansion is the cause of overpressure generation, these methods underpredicted the high overpressure. In the deep overpressured zone, the overpressures were better predicted by applying a correction to the Eaton method. On the other hand, the Bowers unloading parameters for the fluid expansion mechanisms did not show any significant effect on overpressure prediction. Hence, in the study area, the Bowers method is not effective for 3D overpressure prediction using seismic velocity, whereas the Eaton method is more robust and can be used for 3D overpressure prediction from seismic velocity.
