The system can display in 3D the robots with higher quality graphics on PC by adopting the solid model technology, and modify the model of robots according to the size given by users, so that the parametric modeling is realized under interactive mode. It realizes the graphics simulation of robots in kinematics in both articulatory space and Cartesian space, and it also realizes the animated simulation of trajectory of linear interpolation in point-to-point mode.

该系统采用实体造型，能在微机上显示较高质量的机器人的三维图形，可以按照用户给出的尺寸修改模型，在交互方式下，实现机器人的参数化造型；系统能够在关节空间和笛卡尔空间中进行运动学的图形仿真，能进行点到点直线插补轨迹的动画显示，机器人的动作可以示教再现，也可以由程序设定。

With the fast development of economic construction of our country, the safety accident in production is outstanding day by day too, the question of safety in production receives the extensive concerns of the country , government and society more and more, directly subordinate organ as the government sets up the mechanism of safety in production rapidly in the whole country, the safety in production has been laid out the government"s important agenda, but as to new organization of safety in production, difficulty and pressure , opportunity and challenge faced are a lot, how to put the thinking in order in work of thousands of strands and loose ends, catch the focal point, give full play to the role of the government"s supervision and management, turn back the passive state of the safety in production rapidly, it is the focal point that this text discusses.

随着我国经济建设的快速发展，安全生产事故也日益突出，安全生产问题越来越受到国家、政府和社会的广泛关注，安全生产机构作为政府的直属机构在全国迅速建立起来，安全生产工作摆上了政府的重要议事日程，但就新的安全生产机构来说，面临的困难和压力、机遇与挑战是很多的，在千头万绪的工作中如何理清思路，抓住重点，充分发挥政府的监督管理作用，迅速扭转安全生产工作的被动局面，是本文讨论的重点。

Synopsis: To penetrate the continuous development of environment and population during the art teaching, art teachers should not only study thoroughly and tap fully the visible combination point of the EPD education in the teaching material, but also pay close attention to the recessive catenation point of the positive emotion in order to make the students practice the cooperation and innovation, feel the beauty, so as to merge the art teaching and the educational ideology continuous development, then to accelerate the students' all-around, healthy, harmonious and continuous developing.

内容提要：在美术教学活动中渗透环境的可持续发展与人口的可持续发展教育，美术教师不仅要深入研究、充分挖掘教材中EPD教育有形的"结合点"，而且要紧抓积极的情感体验这个隐性的"链接点"，让学生体验合作、体验美、体验创新，使美术教学与可持续发展教育浑然一体、情景交融，进而促进学生全面、健康、和谐、持续发展。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
