基于UML的LCA中产品系统的建模研究

从产品系统本身的内在规律和产品全生命周期的观念研究了生命周期评价(LCA)的对象——产品系统及其特性，建立了产品系统概念模型；利用统一建模语言(UML)建立产品系统的结构模型、功能模型和信息模型，并描述产品系统的建模过程。     

世界文化和不可知论的政见——一个致力于跨文化融洽交流的计划

就世界文化课程内容的具体设置,及联合大学与传媒以更好地实现课程积极目标等诸问题进行探讨.通过多层次的论证强调指出人们始终持有相异或相冲突的宗教、哲学以及意识形态,尚没有一种普世真理足以使世间所有人心悦诚服.即便是广泛接受和运用中的科学知识,其发展亦受阻于人类本身的局限而不可确定.尽管科学在前沿问题研究上竞争激烈,也仍然无法回答和消除所有的问题和差异.因此,从全球或泛人类立场观之,人类现有的知识与理解能力具有不确定和不完整的特点,而这样的特点浸透在所有的具体文化信仰之中.认识到共同局限性的人们--尤其是政界的领导人--亟需摒弃极端的文化分离思想,以更宽容理解的心态思考和行动,这样才能避免不同民族及不同国家间的不断冲突和互相伤害.     

Robot Calibration Using Active Vision-based Measurement

This paper presents an efficient robot calibration method with non-contact vision metrology. Using the coplanar pattern to calibrate camera made the active-vision-based end-effector pose measurement be a feasible and cost-effective way. Kinematic parameter errors were linearized and identified through two-step procedure, thus the singular and non-linear condition was overcome. These errors were then compensated using inverse model method. The whole calibration process is flexible, easy to implement and prevents the error propagation from the earlier stages to the later ones. Calibration was performed on MOTOMAN SV3 industrial robot. Experiment results show that the proposed method is easy to setup and with satisfactory accuracy.

Nuclear Technique and Agriculture in China

Nuclear technique is a powerful scientific tool in agricultural research, an area with fruitful achievements in China. Application of nuclear technique in agriculture (Nuclear Agricultural Sciences) based on the development of related science and technology is a high-tech area, and also a significant aspect of non-electrical power application of nuclear technique. As an important component of agricultural science and technology, Nuclear technique application in agricultural field has achieved a lot and made remarkable contributions to the economic, social and ecological development of China. The current paper reviews the achievements, and presents the situation of the application of nuclear technique in the Chinese a-griculture briefly. The author strongly suggests that Chinese     

Research Frontiers of Agricultural Economics and Management

The focus of research on Agricultural Economics and Management (AEM) has been switching from de-veloped countries to developing countries. In important international journals on AEM such as ““American Jour-nal of Agricultural Economics““ and ““Agricultural Eco-nomics““, the research objectives mainly focus on AEM problems in developing countries, e.g. the effects ofglobalization and liberalization on agricultural produc-tion in developing countries, and problems in agricul-tural resources and environmental protections in devel-oping countries.     

Fabrication and Properties of CoSm-Based Multilayer Thin Films

In recent years, SmCo series thin films have been found to be good candidates for fabricating integrated electromagnetic components and ultrahigh density magnetic recording media[1,2]. Up to now,intensive studies of such films have been carried out in order to obtain appropriate microstructure, crystallographic orientation and other properties. Substitution of Cu or Ni for Co in SmCo/Cr series films leads to a decrease of the saturation magnetization, magnetic switching volume, and to an increase of uniaxial anisotropy and coercivity[3-5].Various deposition conditions have also been investigated[6]. The large increase in coercivity for the annealed SmCo/Cr films is due to the growth of crystallitest[7,8]. In this article, we report a study of the deposition process,structure, and magnetic behavior of sputtered Sm (Co,Cu, Ti)/Cr series thin films.
