Several film were prepared by varying the raw polyethylene(PE) and the content of PE,then the surface patterns and coarse morphology of these film were view by optical microscopy(OM) and atomic force microscopy(AFM) and the average roughness R_a and the profile peak density D were obtained.

Simulation of Surface Roughness and Processing Fault Effects on Microchannel Flows;

Some researchers studied normal contact stiffness between rough surfaces in theory, their researches, however, are all based on the statistically describing results of the micro profile of rough surfaces.

Scattering from 1 dimensional random rough surfaces with varying roughness was investigated by numerical integration based on Kirchhoff approximation.

In order to study the PIM power level as a function of the tightness of the junction, the roughness of the waveguide surface, the thickness of the oxide layer on the metal surface and the input carrier power, firstly developed an equivalent ciurcuit model based on the rough surfaces contact model and then calculated the third order PIM power level using power series method.
