明代留存下来不少财政数据,这些数据均以叙述性文字罗列,给今人利用造成极大困难,急需运用现代统计技术加以整理。但是,由于这些财政数据的来源和性质十分复杂,整理起来有相当的难度。赖建诚教授的《边镇粮饷:明代中后期的边防经费与国家财政危机,1531~1602》一书,在这方面进行了值得充分肯定的尝试,但也出现了一些比较重大的错误。这些错误带有一定的普遍性。这提醒我们在整理解读明代财政数据时应特别注意以下问题:历时性研究必须准确判断财政数字的年代;转录财政数字必须辨清各项目之间的分合关系;比较财政数字必须以性质相同、口径一致为原则;解读财政数字必须明了当时的财政制度。  相似文献

The Hui-style residence is an important architectural heritage of China. The hollow wall structures are widely used to build its exterior wall system. However, the thermal performance of the hollow wall is no longer able to meet the new energy-saving and environmental requirement. This article describes a laboratory study of the development of foamed mortar (FM), with the potential for use in thermal upgrading of the Hui-style hollow wall system without dramatically changing its traditional structure. The key early age, physical, mechanical and thermal properties were systematically measured. Two extended models were respectively developed to calculate compressive strength and thermal conductivity, as a function of porosity. Environment chamber test was also employed to investigate the effectiveness of this novel thermal upgrading approach and the results show that filling the voids with FM can effectively improve the overall thermal resistance of the hollow wall system by 44%, which is almost equal to the overall thermal resistance when using the more expensive commercial inorganic stucco system. In addition, the combination of these two methods yielded an overall thermal resistance of 0.701 m2·K/W, which is even higher than 0.67 m2·K/W for the code required in the hot summer/cold winter climate zone.  相似文献

The increasing availability of telemetry data with high spatial and temporal resolution promises to greatly advance scientific understandings of the movement patterns of individual organisms across space and time. The amount of data provided by such methods, however, can be challenging to analyze and interpret. In this study, we present a new approach for analyzing animal movements that aggregates telemetry locations into spatial clusters and extracts the information from sequences formed by individuals passing through these spatial clusters. We applied this integrated approach of spatial aggregation and sequence analysis to quantify and compare trajectories of cattle (Bos taurus), mule deer (Odocoileus hemionus), and elk (Cervus elaphus) tracked by automated telemetry at the Starkey Experimental Forest and Range in northeastern Oregon, USA. Our approach effectively differentiated movement patterns of the three species. It provides a useful mean of quantifying movement patterns of species in a landscape.  相似文献

Epipaleolithic/early Neolithic settlements at Qinghai Lake,western China   总被引:1,自引:0,他引:1  
Transitions from terminal Pleistocene Upper Paleolithic foraging to Holocene Neolithic farming and pastoralist economic orientations in the northern Tibetan Plateau are examined from the perspective of Epipaleolithic sites located near Qinghai Lake, Qinghai Province, western China. Jiangxigou 2 is an artifact-rich, multicomponent midden site with the main period of occupation dating ca. 9000–5000 cal yr BP, containing abundant flaked stone artifacts including a substantial proportion of microlithic tools, abundant faunal remains including gazelle, deer, and sheep, and a small number of ceramics, including the oldest known on the Tibetan Plateau. Heimahe 3, on the other hand, is a brief hunter's camp dating ca. 8450 cal yr BP, with evident affinities to late Upper Paleolithic camps in the same region that date several thousand years older. The two distinctively different sites are probably nodes within a single Epipaleolithic foraging system that developed on the margins of the high Tibetan Plateau during the early Holocene, and that served as a basis for colonization of the high-altitude Plateau at that time. Jiangxigou 2 appears to be connected to early Neolithic agricultural settlements along the upper Yellow River (Huang He) drainage during the middle Holocene, and may provide insights into forager–agriculturalist interactions that lead to the development of pastoralist systems in the region.  相似文献

马家浜文化区的环境研究,以往都以1000年左右为尺度,即把马家浜文化作为一个基本时间单元来分析,所得结论是粗线条或大趋势性的。在马家浜文化研究近半个世纪的今天,我们已经有条件提取更多信息,变趋势性考察为过程性研究,进而描绘这一时期更加细微的演化曲线,构建人地关系景观。  相似文献
