TEM INVESTIGATION ON AGED ION-NITRIDING LAYER OF PURE IRON

The phase transformation in the diffusion layer after slow cooling and aging of pure iron ion -nitrided was investigated with TEM. Refering to principle of Moire method measuring macroscopical strain, the values of coherent strain at interfaces between a" and aN phases were determined by means of TEM analyses.     

Analysis of Measurement Items Composition under Bills Pricing Mode

This paper analyzes contractor's pricing connotation during bidding period with the implementation of National Standard GB50500-2003 and publish of document JB \206,expatiates the contents of measurements during construction period.Considering the problems derived from expenses of measurements during accounts settlement stage,a classified management method according to the characteristics of these measurements is put forward,and one step further,the rational pricing method of measurement items during the bidding period is suggested.     

System Design for Leather Cavity XCT

This paper introduces a method of solving the problem of leather cavity measurement in shoe CAD/CAM by industrial CT technology. Concentrating on peculiarity and requirement of leather cavity measurement, this paper presents a X-ray industrial CT system scheme, which not only satisfy the requirement of leather cavity measurement but also can achieve general industrial CT. measurement. The achievement on data collection system and motion control of stepping motor is emphasized.     

Development of House Architectural Area Computing and Plotting System

The exact computing of house architectural area and apportionment of area is strongly related to the actual interests of people. If it is done manually,there are many problem such as longer time spending, more workload, requiring detailed verification, nonstandard calculating report. Using ActiveX automation and ADO techniques, the house architectural area computing and plotting system was developed under Autocad R14 environment with VB 6.0 and Access database in order to solve above problem. The developed system can automatically compute house architectural area and apportionment of area for each floor of each building and can print the related data report and drawing. The system works well in many departments of house measurement. Several key technical problem of the system are discussed.     

Correlation and Arithmetic of Operational Risk Measurement Basing on Loss Distribution Approach

Based on the principles of operational risk measurement provided by Basel II,the paper discusses the problem of operational risk correlations among different business lines / risk types.The correlation coefficients between the aggregate losses among different business lines / risk types are calculated.Copula arithmetic is put forward to compute correlation coefficients matrix of aggregate losses.Besides,the result is used to calculate the capital requirement of operational risk.     

Analysis on the Claims Caused by the Defect of Contract

The engineering contract is composed of many documents between client and contractor, such as agreement, notification of award, tender and appendix to bid, conditions for particular application, instruction to bidders, technical specifications, design drawings and bill of quantities etc. Because of the limited time and money to prepare these documents, the defect is unavoidable. The defects include omittance, equivocalness, conflict and mistake. These defects often lead to claims.     

Review on the measurement theories of enterprise knowledge management during the past three years in China

The implement of enterprise knowledge management gives rise to extensive research on its measurement. Based on the existing measurement theories and evaluation index systems of enterprise knowledge management during the past three years in China, this paper analyzes the problems in measuring target and designing the evaluation index system in the existing research findings, and explains detailedly why measurement target of enterprise knowledge management should be "level evaluation" instead of "performance evaluation", and definitely points out the meanings of enterprise knowledge management level and significance of its evaluation. This paper also indicates that the design of the evaluation index system should be complete, reasonable, proper and operable.     

Research on Measurement and Report of Environmental Accounting

In this paper, the problems of bringing natural resources and environmental condition into accounting are discussed and lay emphasis on object measurement, imaging and disclosure in accounting report of environmental accounting. The author suggests that the environmental accounting is the necessary production of global economy for sustainable development in modern society; it is also a new ecological accounting subject formed by the result of environmental economies and accounting penetrating into each other. As a contribution of accounting circles to sustainable development, environmental accounting has become a hot topic in recent years.
