This paper deals with the intermediate results of the development of a national standardized classification system called JCCS to ensure harmonized use of various kinds of information to be processed through the whole life cycle of construction projects in a nation-wide Japanese CALS/EC scheme. JCCS is planned to be a Japanese IFD and developped on the technical basis of ISO 12006-2 and 12006-3. Japan has currently no such an IFD-like library of terminologies which is to be an essential tool for the multiple and harmonized information processing, so that JCCS should be a key technology for the successful CALS/EC. First, the development concepts and related technologies are described. Second, evaluation of the current situation of information process in the construction industry is clarified, and followed by the requirements of the development of JCCS. In the main part, the current version of JCCS is outlined, major contents of which are the basic architecture of JCCS, JCCS schema, JCCS basic tables and the usage of JCCS in practice. Finally, future develoment in plan is briefly explained.  相似文献

Click-streams of online shopping are the tracks/trails of interactions between a customer and a vendor.We observe that it is of great importance both in theory and practice to explore a deep analysis method for analyzing click-stream information of an individual customer in a specific transaction for understanding the bidirectional value transfer within the machine-human interaction of an online store and for its personalization.We analyze the significance,the hierarchical structure and the characteristics of click-stream information and propose that Ricoeur's hermeneutic theory be the foundation of forming such a deep analysis method.Then we use the empirical context information of the click-stream to improve the naive interpretation put forward by Ricoeur.Moreover,we apply the Grounded Theory to extend the deep analysis of Ricoeur's theory of textual interpretation.The improved theory fits well with the needs of interpretation and the analysis of click-stream information.We exemplify and show the feasibility of this analysis method by using data collected(a single case)from a large study of human-computer interaction.  相似文献

The Major Research Program "Deep Sea Processes and Evolution of the South China Sea", or "The South China Sea Deep", launched in January 2011 by the National Natural Science Foundation of China, is the first large-scale basic-research program in ocean science in the country aiming to reconstruct the life history of a marginal sea. The overall scientific objective of the program is to dissect this typical marginal sea by studying its history of evolution and its modern processes, including the following three major components:(1) Development of the deep basin:utilizing new techniques to re-measure magnetic anomaly lineations, to explore the deep tectonic features, to drill the oceanic crust, and to study volcanic seamount chains; (2) deep-water sediments: observing the modern processes to reveal the patterns of deep-water circulations and sedimentation, analyzing deep-sea sediments to recognize paleoceanographic response to basin evolution, and subsequently to bridge the modern and paleo-studies of the deep-sea processes; and (3) biogeochemical processes:using a variety of techniques including deploying submarine observation and deep-water diving device to investigate the distribution patterns and environmental impacts of deepwater seepages and sub-bottom circulation, and to reveal the role of microbes in deep-sea carbon cycling. As compared with the open ocean and other marginal seas, the South China Sea enjoys many more advantages as a marine basin for reconstructing the life history. Meanwhile, the South China Sea Deep Program provides unique opportunities in studying the evolution and variations of the sea-land interactions between the Pacific and Asia.  相似文献

The landfalling processes of Typhoon "Haitang" near Lianjiang of Fujian Province of China from 00 UTC 19 to 12 UTC 20 July 2005 were reproduced by using the nesting non-hydrostatic WRF model and data assimilation technology (Level II Doppler radar data of Changle of Fujian Province are assimilated to the simulation every one hour from 01 to 06 UTC 19 July 2005). The mesoscale structure and evolution of the typhoon before, during, and after its landfall were discussed. The simulation data show that the assimilation exper- iment with the high temporal-and-spatial-resolution radar radial velocity and reflectivity data can produce much better simulation of the typhoon track, intensity evolution and landfalling location than the control experiment without assimilating radar data. By using the assimilation experimental data, the mesoscale fine-mesh structure and evolution before and after typhoon landfall were analyzed. Because of the influence of sea-land thermodynamic difference, two asymmetric convective regions were located at ocean and land, respectively. To better understand and investigate the asymmetric-structure characteristics of the landfalling typhoon, several dynamical diagnostic tools, the helicity (H), the moist potential vorticity (MPV), the convective vorticity vector (CVV), the moist vorticity vector (MVV), which are associated with the development of strong convections, are introduced. Further analysis illuminates that the distribu- tions of these physical diagnostic parameters are totally asymmetric, and subsequently, the associated convections also show distinct asymmetry.  相似文献

A record of “double dawn” at State Zheng in the first year of the reign of King Yi in Western Zhou Dynasty in the chronicle “Bamboo Annals” (Zhushu Jinian) is discussed. We think that it may be a record of an annular solar eclipse happening in 899 BC. The record and the †T, which describes the secular variation of the earth’s rotation, are analyzed and discussed.  相似文献

In the comments “the cause of crustal deformation in the vicinity of Zhangbei earthquake area” (hereafter referred to as “Cause”), the authors propose a new seismic focal mechanism of Zhangbei-Shangyi earthquake occurring on Jan. 10, 1998. which opposes our D-InSAR model. They assume that the displacement measured by D-IuSAR is not the surface representation of seismic  相似文献

To improve the numerical simulation of the severe snow storms occurred in the south of China and the middle/lower reaches of Changjiang River during January of 2008, the observations from the automatic weather stations (AWS) over the Qinghai-Xizang Plateau (QXP) and its surrounding areas were assimilated into the Weather Research and Forecasts (WRF) model using multi-cycle 3-dimensional variational data assimilation (3DVAR). Due to the large-scale special topography of the QXP and its surrounding areas which may reach up to the mid-troposphere, the AWS located at different height on the deep slope of the plateau are different to those located on plains and take a role analogous in some extent to that of radio soundings in obtaining the vertical “profile” information of the atmosphere, and have the advantages in the aspects of sampling frequency, location/height fixing, and synchronization. The information captured by these AWS may carry the early-warning “strong signals” in the upstream sensitive area for the downstream weather systems to the east of the plateau and thus the assimilation of these AWS data is expected to lead to significant improvements on the simulation of the severe weather system occurred in its downstream areas through adjusting the 3-dimensional structures of the atmospheric thermal-dynamics for the initial conditions of the model. This study indicates that the assimilated information of moisture, temperature and pressure carried in the observations of AWS over the Qinghai-Xizang Plateau and its surrounding areas is very important and useful in the forecasting of precipitation in its downstream areas.

在对《离骚》的接受过程中,司马迁的悲其志历来是人们关注的重点。但在理解这句话时,人们多从司马迁与屈原的悲剧性人生理解,这并不能达到十分准确的理解目的。结合《离骚》和《屈原列传》,可知司马迁的悲其志与《离骚》的内在情感是一致的。屈原之志主要指其高洁人格、忠君爱国理想和怀才不遇的经历,而司马迁的悲其志表现的正是对屈原高洁人格和忠君爱国理想的赞美以及对其怀才不遇的哀伤。  相似文献
