炉渣滤床技术处理亚麻生产废水

为了确定处理包头亚麻厂亚麻生产废水的设计方案，设计之前在现场进行了生产试验。在包头亚麻厂污水处理站，模拟炉渣滤床制造了3米高的炉渣滤层，滤渣从工厂锅炉房取用，将实际排放的亚麻煮漂车间、细纱车间、粗纱车间的生产废水混合后，通过炉渣滤层过滤处理，处理后出水由厂化验室和包头环保局化验。试验结果表明，处理后的排水各项指标完全达到国家排放标准。该工艺处理费用低，运行效果稳定，管理简便，具有明显的经济效益、环境效益和社会效益。     

浅谈发挥低年级学生学习英语的积极性

英语教学，特别是低年级英语教学既需要教师的积极性，更需要学生的积极性，二者缺一不可。要想发挥学生的学习积极性，首先应发挥英语自身的魅力，启发学生的积极性；其次，以情感促教学调动学生的积极性；再者，采取有效措施巩固学生的积极性。

三维模型中关键特性标注和提取的实现

关键特性作为"少数重要"的产品信息,是保证产品质量和顾客满意度的重要因素,其指定和标识需要与三维模型相结合才具有更直观的意义,同时也方便对其进行更有效的管理.本文给出了关键特性的定义和分类,提出了三维模型中关键特性的标注方法,通过对UG进行二次开发,实现了关键特性的属性添加和信息提取,并通过某型导弹弹头舱段壳体零件进行了验证.     

Digital Aircraft Sheet Metal Part Manufacturing System and Its Key Technology

The architecture of digital sheet metal manufacturing system is proposed based on the classification of sheet metal manufacturing information.The essence of digital manufacturing is the definition,management and transfer of information,and the key technologies are brought forward and described.It is pointed out that knowledge-based manufacturing elements design is necessary to make digital technology efficient.The management of all kinds of sheet metal manufacturing element information is to build single source of manufacturing data.Multi-state model-based digital transfer and coordination method is designed to provide a foundation for digital manufacturing of aircraft sheet metal part.The application of digital sheet metal manufacturing is exemplified with an aircraft sheet metal part.The application result is compared to that of the traditional analog transfer technology.It is shown that the developed technology can improve part quality,shorten manufacturing time and lower manufacturing cost.     

超声波法测量燃速初探

针对国内首次引进的超声波实时燃速测量系统编写了测试软件,用水作为被测试对象,进行了退移速率测量,分析了超声波测量燃速的主要影响因素。结果表明,测量精度主要受材料中声速的约束,声速会受到材料应力(压强)和温度的影响。该软件可以用于厚度、材料内声速和实时燃速测量。     

Earthshine and Asteroseismology Telescope (East) Network

Several automated optical telescopes have been setup at appropriate longitudes around the globe to study earthshine variations and asteroseismology. The first telescope has been setup at Teide Observatory, Tenerife, Spain in October 2004. The intensity of earthshine relates to the average of Earth’s albedo, and in turn relates to the global temperature of the Earth. A global network is necessary because each site can measure the earthshine reflected from only a part of the Earth. The network will also be used for asteroseismology study. It can measure photometric variations of pulsating stars. The long-term and continuous measurements allow the accurate determination of mode frequencies of stellar pulsations, which provides information on the properties of stellar interior.
