The Capacities Evaluation of Oil Absorption Materials Dongming Wei a, Hongbo Zheng band Shushen Zhang Key Laboratory of Industrial Ecology and Environmental Engineering (MOE), School of Environmental Science and Technology, Dalian University of Technology, Dalian 116024, China aemail:0325dongming@163.com bemail:dlhongbo@126.com Keywords: Oil absorption materials; capacities; comprehensive evaluation Abstract：Nowadays, more and more oil-absorbing materials are researched, but lacking of an effective index system to evaluate capacities of oil-absorbing materials.
At present, the common oil-absorbing materials are divided into three categories: natural mineral oil-absorbing materials, organic materials and synthetic polymer materials.
More and more oil absorption materials are collected, researched and developed.
On the other hand, how to deal with these oily materials[4].

Effect Of Different Sintering Temperature On The Performance Of Mullite-Corundum Refractory Materials LI Ping1,2, GU Xing Yong1,2,a, LUO Ting1,2and Chen Yun Xia1,2 1Jingdezhen Ceramic Institute, Jingdezhen, Jiangxi, 333403, China 2Jiangxi Provincial Key laboratory of advanced ceramic materials, Jingdezhen, Jiangxi, 333403,China aguxing-y@163.com Keywords: Sintering temperature; Mullite whisker; Formation in-situ; Refractory materials Abstract.
The mullite-corundum refractory materials with well-dispersed needle-like mullite formed in-situ were prepared.
Secondly, calcined bauxite and Suzhou kaolin, the raw materials of the sintered materials, were weighed, wet grinded, dried and then sieved by 120 meshes.
Finally, the grinded and sieved raw materials of the sintered material and the granulated precursors of mullite whisker were weighed respectively and mixed uniformly according to the designed mass ratio of 7:3.

The critical density between masonry materials and lightweight materials is defined as 2000kg/m3 here.
The result of Fig.1 (a),(b), which shows that the coupling loss of masonry materials less than materials can also prove it.
Fig2 (b) shows the η RW of lightweight materials, which value is less than masonry materials at the same frequency.
It means that sound insulation performance of masonry materials is better than that of the lightweight materials.

Experimental Study on Cryogenic gas atomization Jet Cooling difficult-to-cut material Xiaoyan Guan1,a, Aisheng Wu1,b 1Jiangsu University of Science and Technology, Zhenjiang Jiangsu 212003, China aguanxiaoyankb@163.com , b22871120@qq.com Keywords: Cryogenic gas atomization jet cooling, difficult-to-cut material, cooling experiment.
It is indicated that the water dose to the best cooling effect must be equivalent to the amount of water that materials can vaporize and participate in the phase-change heat transfer under certain temperature.
When the water dose adds to 2ml/min, the droplets is same to the the amount of water that materials can vaporize and participate in the phase-change heat transfer under certain300℃ on nickel-base alloy surface.
The number of droplets which can vaporize and participate in phase change heat transfer is certain under Specific materials at a specific temperature, that is "vaporization capacity" of the material at the temperature.
