人类学视角下的祠堂重建——以江西某村落为个例

从人类学的视角出发，从社会结构等方面进行探讨和分析，可以发现祠堂重建不是一个简单的社会行为，而是社会经济发展与权力博弈的产物。它不仅影响了人们的日常生活，帮助人们寻找以祖先崇拜为基础的归属感，团结了族人，强化了宗族意识，在村落之间也有利于树立本族的新形象、提高本族的声誉。从本质上说，祠堂重建并非一种传统文化的有意识的保护，而是当下社会人们的一种积极选择，这种选择有意无意间促进了村落内部的团结与和谐，同时，也让人们在物质增长的基础上得到更多的精神认同。

号称经典物理留下的世纪难题“湍流问题”的实质是什么？

一直以来,湍流都被认为是经典物理留下的世纪难题,因而也被认为是一个重大的基础科学问题.本文简单回顾湍流研究历史,分析了均匀各向同性湍流的研究和真实湍流的研究间为何存在鸿沟.为何前者不能解决真实湍流问题,而后者则是今后应重点开展的湍流基础研究,和如何逐步解决真实的湍流问题.在结论中提出了今后湍流研究中值得注意的几个方面.     

Soil oribatid mite (Acari: Oribatida) diversity and composition in semi-deciduous forest fragments in eastern Amazonia and comparison with the surrounding savanna matrix

We recorded species abundance and richness of oribatid mites along 16 plots established in semi-deciduous forest fragments in Amazonia. The results were compared with a published dataset consisting of an inventory carried out in 38 plots in the surrounding savanna. Totals of 143 and 91 species were recorded in the forest fragments and savanna, respectively. Sørensen similarity index between both environments was 0.44. Ordination of sites according to oribatid mite species composition showed a clear separation between forest fragments and savanna. Rostrozetes ovulum, Archegozetes longisetosus and Eohypochthonius (Eohypochthonius) becki were abundant and frequent in the forest fragments but exceedingly rare in the savanna. Neoppia (Neoppia) schauenbergi, Pseudoppia sp. C, Microppia sp. A and Cosmochthonius sp. A were limited to the savanna. This study also represents an early step toward knowing which groups of species are exclusive to one or another vegetation type or are sensitive to their inherent environmental conditions.     

路面热平衡过程中下沉式道路结构应力及影响因素的数值分析

以某下沉式道路为研究对象，运用有限元法分析了路面热平衡过程中道路结构的应力分布情况，以探讨道路结构可能发生破损的原因和位置，结构抗浮底板层的弹性模量和厚度，以及结构抗浮底板层中铺装钢筋配筋率及其铺装位置对其应力的影响.结果表明，在下沉式道路结构中，极有可能在连续配筋混凝土层的底部最先产生张开型（I型）裂缝，且结构抗浮底板层的厚度和铺装钢筋层位对I型裂缝的影响较大.

急倾斜煤层采空区结构特征GPR探测

急倾斜煤岩体结构和地质缺陷具有隐蔽性。历史性无序开采形成的采空区分布的不规则性严重影响安全开采。以神新小红沟煤矿急倾斜煤层开采区域空区分布规律预测与参数确定为目标。通过理论分析、GPR地面与地下立体联合探测,分析了+522水平B3和B6开采扰动范围内采空区结构特征。+522水平距五一煤矿巷道垂直距离约为35.0～35.5 m.B3巷1 214～1 232m范围内空区覆岩破坏严重,多处出现破碎区。空区下部近似椭圆,上部似半椭球体结构,且空区已联通。1 232～1 250 m范围空区及覆岩破坏严重,局部区域积水量大,为现场开采设计与灾害防治提供科学依据。

Sedimentation processes and sedimentary characteristics of tidal bores along the north bank of the Qiantang Estuary

A tidal bore is a unique Earth surface process, characterized by its highly destructive energy, predictable periodicities and magni-tudes, and the production of characteristic sedimentary features. Tidal bores and associated rapid flood flows are highly turbulent flows of the upper-flow regime with a velocity over several meters per second. Reynolds (Re) and Froude (Fr) numbers, respectively, are larger than 104 and 1.0, making them significantly different from regular tidal flows but analogous to turbidity currents. Until now, understanding of tidal-bore depositional processes and products has been limited because of the difficulty and hazards involved with gauging tidal bores directly. The Qiantang bore is known as the largest breaking bore in the world. Field surveys were carried out in May 2010, along the north bank of the Qiantang Estuary to observe the occurrence of peak bores, including regular observations of current, water level and turbidity at the main channel. Several short cores were sampled on the intertidal flats to study the characteristic sedimentary features of tidal bores. Hydrodynamic and sedimentological studies show that the processes of sediment resuspension, transport and deposition are controlled primarily by the tidal bores, and the subsequent abruptly accelerated and decelerated flood flows, which only account for one tenth of each semidiurnal tidal cycle in the estuary. Tidal-bore deposits are generally poorly sorted because of rapid sedimentation after highly mixed suspension by intense turbulence. This behavior is characteristic of the absence of tractive-current depositional components in a C-M diagram. It also goes along with well-developed massive bedding, graded bedding, basal erosion structures, convolute bedding and dewatering structures. Together, these sedimentary features can constitute fingerprinting of turbidites, widely distributed in the deep-water environment. However, a tidal bore is triggered by intensely deformed tidal waves propagating into a shallow-water environment, which returns to regular tidal flows rapidly after the passage of the bore head. The tidal-bore deposits are usually bounded by the intertidal-flat deposits with typical tidal beddings at the top and on both flanks. The difference between tidal-bore deposits (TBD) and tidal sandy/muddy deposits (TSD/TMD) is evident not only in sedimentary structures, but also in the grain-size composition. They can be clearly distinguished in grain-size bivariate plots, typically the plot of mean grain size vs. standard deviation (or sorting). Some trend variations generally exist in mean grain size with TBD>TSD>TMD, sorting with TMD>TBD>TSD (larger value indicating poorer sorting), and both skewness and kurtosis with TSD>TBD>TMD. These findings will undoubtedly shed new light on our understanding of tidal-bore sedimentology, ancient tidal-bore sedimentary facies and environments, and related oil-and-gas field prospecting.
