Generally, there are charges on most interface between solid and liquid, that is, when electrolyte contracts the surface of solid, the surface will produce charges for ionization, ion adsorption and ion dissolution, and other complex chemistry.
Based on equation 13, if a structure like as Fig.6 is designed, where the zeta potential is adjustable, the condition of changing ζ will be improved by changing material of microchannel or electrolyte in microchannel, at the same time, it increases the control ability on EOF. 0 0.25 0.5 0.75 1 1.25 1.5 0 0.0025 0.005 0.0075 0.01 0.0125 0.015 y(µm) u(µm/s) u distribution ζ=-75mv E=1000V/cm E=1500V/cm 0 0.25 0.5 0.75 1 1.25 1.5 0 0.0025 0.005 0.0075 0.01 0.0125 0.015 y(µm) u(µm/s) u distribution E=1000V/cm ζ=-75mv ζ=-150mv Fig.4 EOF velocity(ζ��75mv) Fig.5 EOF velocity (E=1000V/cm) Fig.6 Microfluidics control principle Conclusion Based on the special example and the forming mechanism of EOF, an EOF mathematic model is developed.

This type of iron is typically weakly oxidized and possesses a fine-dispersed, porous structure.
An increase in scattering intensity in the 5°–10° 2θ range may suggest the formation of microporous carbon structures.
As a result, the smaller MB molecules may adsorb more effectively in the porous structure of MC1.

The research of Corroded stell-structured surface characteristic Shanhua Xu 1, a, Bin Shi1, b, Xinlong Yang1, c 1School of Civil Engineering, Xi'an University of Architecture and Technology, Xi'an 710055, China axushanhua@163.com, bshibinxa@163.com, cyangxinlong568@163.com Keyword:corroded steel structural; three dimensional parameter evaluation; fractal dimension Abstract.
Parameter method and fractal theory are carried out for appraising corroded the stell-structured surface of the atmospheric acid corroded the environment.
Provided three dimensional parameter definitions. reference datum and computing method of fractal dimension, adopted non-contact-type infiniteFocus full-automatic zooming 3-D superficial measuring apparatus and MATLAB software to deal with the resulting data of the experiment, the results show that parameters method and fractal theory to comprehensive evaluation of corrosion surface of steel structure is more reliability.
Introduction It means the steel component is influenced by surrounding environment medium (mainly include factors such as chemistry, electrochemistry, etc.) to lead to the fact the structure is destroyed and dropped with performance to corrode the steel construction.
It is medium through leading to the fact to superficial gradual influence the steel construction is destroyed finally, so have important meanings in the research of the corroded stell-structured surface characteristic.

Recently, Bernstein reported that there has been a great interest in polymorphism, as an intrinsically interesting phenomenon including this LaYO3 compound based on the point of view of its crystal chemistry.
Polymorphism is the multiplicity of structures which refers to the existence of more than one crystal structure for a particular chemical substance [14].
Samples sintered at lower temperatures (i.e 1250 °C, 1300 ˚C, 1350 °C, 1400 ˚C,1450 ˚C) have orthorhombic structure with existence of secondary phases, meanwhile samples sintered at higher temperature 1500 ˚C have single phase with ordered monoclinic structure.
