Density is a key of fuel property which directly affects an engine performance characteristic [2, 15, 16].
This includes rearrangement of product of similar molecular weights to give short chain aldehydes, acid compounds and high molecular weight materials [19].

Numerical Simulation of Laminar Flow Field in a Stirred Tank with a Rushton Impeller or a Pitch 4-Bladed Turbine Junling Fan1,a , Deyu Luan1,b 1 School of Electromechanical Engineering, Qingdao University of Science and Technology, Qingdao, 266061, China akeda2973@163.com, bqddy05@163.com Keywords: Rushton impeller, pitch 4-bladed turbine, stirred tank, laminar model, numerical simulation Abstract.
In such cases, Poorly designed mixing processes cause substantial increases in waste production at the expense of valuable raw materials and desired products, especially, in the laminar flow regimes.
While efficient mixing is often (but not always) achieved under such conditions, there are many applications for which turbulence is precluded because fluids are too viscous or because they contain materials that are shear sensitive and may become damaged by vigorous agitation.

Analysis and Evaluation of Heavy Metal Pollution of Surface Soil in Baicheng City Gang Wang*a School of Mechanical Engineering ,Baicheng Normal College, Jilin, China a haohehe@163.com Keywords: Baicheng City; Heavy Metal Pollution in Soil; Fuzzy Comprehensive Evaluation Method; Factor Analysis Method Abstract.
The key of factor analysis is to calculate feature value and accumulated contribution rate of relevant factors by the matrix of relevant coefficients; those in the living quarter can be seen in table 7.
The pollution area of Zn and Cr is large, indicating that pollution of these two metals mainly comes from additives of building materials of building in the urban areas and tyres of automobiles and waste batteries which are not processed well.
On the whole, the concentration distribution of heavy metal shows certain area difference which is mainly related to the functions of the areas and generally speaking, industrial areas and commercial areas are subject to heavy pollution. 2)Results from the research and analysis of the types and source of soil heavy metal pollution in Baicheng City via factor analysis show that the major pollution factors Hg, Cr, Cd, Cu and Pb of industrial areas are mainly from coal emissions and "three wastes" discharge from factories; the major pollution factors Pb, Cu, Zn, Ni and Cr of the green areas of the parks mainly come from household garbage deserted by residents; the major pollution factors Cu, Cr and Ni of the main roads are mainly from road construction, dust emission and road landfill; the major pollution factors Pb, Cd, Zn, Cr, As and Ni of living areas mainly come from vehicle exhaust emission, usage of addition agent for building materials and tires, improper disposal of wasted batteries

Evaluation of Tobacco Mixing Uniformity Based on Projection Pursuit LI Junli1,a , MAO Jianlin1,b, YIN Gengyun2,c 1College of Information Engineering and Automation, Kunming University of Science and Technology, Kunming 650051 2Yunnan Academy of Tobacco Science, Kunming 650106 1 a knight140928@163.com, b km_mjl@yahoo.com.cn, c gyyin163@163.com Keywords: mixing uniformity, coefficient of variance, projection pursuit model, genetic algorithm, index weights Abstract: A new comprehensive evaluation method of tobacco mixing uniformity was presented in this paper.
Mixing Uniformity Mixing refers to two or more materials mix in the external force, so that each component in the unit volume or unit weight distributes uniformly.
It was the key that to scientifically select the evaluation index and the establishment of an appropriate evaluation system during the process of comprehensive evaluation.
It can be seen from Table 4 that the mixing uniformity of tobacco products were improved significantly after the raw materials mixing process.
