Application of a nano-material releasing anion on rice paper Fang Wang ,Qingshan Li,Fubin Li State Key Laboratory of Metastable Materials Science and Technology, Yanshan University Qinhuangdao, 066004, China Keywords: nano-structure material , opal ,rice paper, anion Abstract: A nano-material named opal blended with polymer, then were added into slurry, after a series of special paper-making process, the rice paper releasing anion was successfully prepared by us.
With the development of social science and technology, environmental protection is increasingly becoming the common concerns of all humanity.
Based on our past experience, we added natural mineral materials in the process of production of rice paper, fortunately, it has the function of the releasing negative ions.
Nanometer materials of opal was a kind of natural mineral material modified in Qicai Technology Company of Yanshan University[1].

In this paper, Continuous Basalt Fiber (CBF) was used as the raw materials, and then woven by the Digital sample looms.
The CBF, would be bound to play a significant role in future of fire-retardant materials and high-temperature composite materials, exhibited excellent flame resistance and heat resistance.
Results and Discussion 3.1 Results 3.1.1 Limiting oxygen index test The limiting oxygen index(LOI), reflected the burning behavior of the materials, is the minimum oxygen content to support combustion of materials in nitrogen-oxygen mixed gas, and abbreviated as LOI.
Therefore, Basalt fibers would have broad prospects in the area of flame-retardant composite materials.

Although the critical aspects of hazardous and toxic materials within oily petroleum sludge had been widely addressed, very little attention had been given to NORM and TENORM in such sludge.
As for recyclability, it promotes extracting and recycling the available materials from the sludge matrix to be used as an alternative energy source.

Volume Measurement of Large Material Stack Based on the RBFNN Interpolation Chen Chun, Yang Weimin, Zhang Pengxin Northeastern University, China No.11, Lane 3, Wenhua Road, Heping District, Shenyang, 110004 China chenchunsy@163.com, yangweimin@ise.neu.edu.cn, zhangpengxin510@yahoo.cn Keywords-RBFNN interpolation; material stack’s volume;computer aided measurement.
Abstract This paper presents a quantitative method of measuring the volume of material stack.The material stack is divided into many little rectangular columns,then the material stack’s volume will be got by calculating each rectangular column’s volume.At the same time,a measurement system is designed to achieve the automatic measurement, three-dimensional reconstruction, and volume measurement.
Fig.7 The reconstruction figure of 0.81L actual material stack Conclusion This paper presents a method of quantitative measurement of material stack,use two cameras to obtain left and right pictures,then use interpolation method to split the material stack,and calculate the volume.The experiment proves that,this method is simple and easy,high accuracy,and conform to the actual need.

Introduction Statement of the Problem Teachers want to give the lessons to raise up students capability in their fields, and students want to learn what they feel interesting, in the classroom, text book, materials, hand out, and oral explanation are to teach theory.
The application, the creative beauty show teaching can increase the motivation by providing vary sub-system and interesting matters, and can store the teaching data and materials as well as the disks.
For the efficiency teaching, all of materials are applying on the computer system to perform, the students are not just sit on classes for learning, they can see more demonstrations, and learn more about the beauty design, the teachers can provide more different teaching methods, the efficiency of computer teaching is better.

Some scholars especially in developed countries have paid attention on how to upgrade the properties of cement and concrete materials to the grade of aluminium, steel and fibre materials.
Experimental Materials.
Therefore, the greatest packing density of the cement-based materials increases from 0.72 to 0.80 and the strength of the cement-based materials rises.
