Spatial Distribution and Potential Ecological Risk Assessment of Heavy Metals in Roadside Soils on Different Operated Times along the Lianyungang-Horgas Highway Lei Gu1, a, Bo Song1, b, Zhiqi Tong1, 2, c and Jianhua Ma1, 2, d 1 Institute of natural resources and environment, Henan University, Kaifeng 475004, China, 2 Henan open laboratory for key subjects of environmental change and water-soil pollution control, Henan University, Kaifeng 475004, China agulei1981@126.com, bsongbo@henu.edu.cn, ctzq@henu.edu.cn, demailmjh@henu.edu.cn, corresponding author Keywords: Lianyungang-Horgas Highway, roadside soil, different operated time, heavy metals, potential ecological risk.
Materials and Methods Sample collection Wanliu transect on Zhengzhou-Kaifeng section and Xiaowangzhuang transect on Kaifeng-Shangqiu section along Lianyungang-Horgas highway were selected as the study transects (Fig.1), the first section operated in 1994, and the second section in 2001.
Sample preparing and heavy metal determining In laboratory, after intrusive substances and plant materials in samples removed, the samples were air dried, grinded with an agate mortar, wholly sieved through a 1 mm aperture nylon sieve and well mixed, and then about 100 g soil samples were selected from 1 mm samples, grinded and passed through a 0.15-mm nylon screen wholly.
It had been discovered that Pb, Cd, Cu and Zn in roadside soils originated from oil exhaust, oil leaks, tire wear, brake abrasion, and radiator, and so on, so they were classified as typical traffic source metals; and Ni and Cr were classified as mixed source metal which originated not only from soil parent materials but also traffic activities [11, 13, 14].

Fuzzy comprehensive evaluation of the mode of the Mining Urban economic transformation Liu Lie-wu1,2,a, Song Huan - bing1,b 1.Faculty of Land Resource Engineering,Kunming University of Science & Technology,Kunming 650093,China 2.
That is to say, by providing raw materials industry primary industry products, precision and deep processing industry development, mining city development eventually form the deep processing industry mode, the core of which is technology intensive industry.
The essence of this kind of mode is the optimization and upgrading of industries, namely the production of primary products raw materials industry proportion drops, proportion of manufacturing intermediate products, final products industrial rises and gradually occupy the main position, so as to cause the high scale of industrial structure.
Inner Mongolia building materials,chemistry, metallurgy, energy and such industry bigger and stronger, make the industry in the national economy play a pillar role.
After the founding of new China, it was included in “the first five-year plan”key construction projects.

Aromatic imide (N-phthalimide) group was firstly introduced as electron acceptor in the donor-π-acceptor (D-π-A) opto-electronic materials.
Because of their high solubility and excellent thermal stability, fluorene-based materials have emerged as promising classes of organic semi- conductors in the field of organic electronics, especially in OLEDs [2-5].
Therefore, it will be interesting and meaningful to introduce imide to these materials.
All the interesting electrical and photophysical properties made these materials quite promising for the applications in OLEDs.

Both the mathematic models of air brake system and vehicle are very complicated since many differential equations need to be solved and many parameters may be correlated with each other, especially the parameters for the key components, such as brake valve, relay valve and pipelines.

Mickiewicza 30, 30-059 Krakow, Poland pmigas@ agh.edu.pl, mkorolcz@agh.edu.pl Key words: Rheology, Slag Viscosity, Blast Furnace, Hearth Lining Abstract: The applying of burden materials containing titanium compounds in the blast furnace process and the processes of forming titanium carbides and nitrides has a directly impact on the physical and chemical properties of slag and pig iron.
Due to the prevailing conditions inside, the hearth of the blast furnace is made up of graphite, carbon, carbon-graphite, and microporous materials.
Charge materials with titanium compounds have started being used in order to extend the life of the refractory lining and the service life of the blast furnace.
