On the basis of the current situation of the evaluation method of higher education,this paper analyses the quality evaluation of higher education based on the criteria for performance excellence. The results show that introducing the criteria for performance excellence to the evaluation of higher education quality, on the one hand, we can overcome the disadvantages of previous evaluation index system of higher education, on the other hand also bring the innovation of the management for the education quality of higher education. This paper puts forward some suggestions and implications to the objective evaluation of higher education quality.

The ability of business executive is one of critical factors to influence the enterprise's existence and development.Given that the executive's ability belongs to soft variable,the previous studies usually neglect it,which leads to the existence of certain differences in the research conclusions.Based on the characteristic of executive's ability,the paper constructs the evaluation indexes system of the executive's ability.Using fuzzy analytic hierarchy process,we quantitatively analyze the executive's ability,and give the concrete quantization procedures with the example.Finally,this study provides the quantization indexes for measuring the executive's ability.

At present,the reasons why many people are suffered from lots of occupational diseases is that many office chairs are not accord with human body.In this paper,through the analysis and research on design of office chair,combined with the application of various factors of human engineering in office chair,people-oriented ideas is fully embodied,which provides theoretical guidance and research on the design of office chair according with human body.

复合材料(Composite materials),是由两种或两种以上不同性质的材料,通过物理或化学的方法,在宏观上组成具有新性能的材料.由于各种材料在性能上互相取长补短,产生协同效应,使复合材料的综合性能优于原组成材料而满足各种不同的要求,其中以树脂基复合材料应用最广.

This paper introduces the practical significance of the cash flow analysis,the contents of cash flow analysis,methods of cash flow analysis,cash budgetary control,control of cash flow problems.

To solve the uncertain multiple attribute decision making(MADM) problem of the performance evaluation and selection of suppliers,a multi-attribute-fusion model is developed via the DSmT.In the frame of DSmT,we transfer the evaluations by the guidelines to the belief values first;then,combining with the importance of guidelines we discount the belief values which are educed before.At last,the discounted belief values are fused to the final values:the final result of the performance evaluation.An example is given for the evaluation of suppliers to verify the effectiveness of the proposed method.

计算机辅助设计,英文缩写为CAD.计算机辅助制造,英文缩写为CAE.这项技术是伴随着计算机技术的发展而发展起来的,距今才短短的四十多年.CAD/CAM技术发展到现在已经有了很大的进步.现在的CAD/CAM软件主要在工作站或微机平台上运行.工作站的优点是图形处理速度快,性能好,但缺点是价格一直居高不下,给企业增加了成本,这就限制了CAD/CAM技术在工作站上的推广.随着计算机技术中Pentium芯片和Windows NT操作系统的出现并流行,CAD/CAM软件找到了新的运行平台.

Establishing basement wall board finite element model,the basement outter wall and floor bottom are influenced by flexible restriction of soil.The thermal stress caused by basement outter wall and bottom board at the changing of tempreature are studied.Through the finite element analysis,the distriction situation of thermal stress at climate change process are mapped and the law of thermal stress's change with wall length and bottom thickness is qualitatively summarized.

本文时现役CAD/CAM系统在NC刀轨生成方法上进行了对比分析.

本文只考虑墙体混凝土龄期达一个月后对其进行分析,并结合"王铁梦法-温度应力计算公式"研究墙体在环境温度变化以及同时期内混凝土收缩、徐变下的结构效应(应力、应变等)—本文统一称之为"环境温度效应"。本文以沈阳市气候特点为研究背景,找出最不利时的季节温差从而计算出外墙环境温度收缩应力。
