Introduction Pipe connection fits (PCFs) (Fig.1), particularly those made of lightweight materials and had a conical sealing surface, provide excellent sealing performance, which together with their small size has made PCFs being widely used in the pipe systems of aircrafts and engines [1，2].
A PCF is a multi-body & multi-contact mechanical connection component, whose sealing performance is determined by the complicated contact states and the mechanical properties of the materials.

This heat dissipates into the surrounding material – welding pieces, the temperature of the material rises and it softens [6].
The tool rotation and traversing leads to extrusion of material.

Some less common phenomena are hereby described such as dielectrics etching rate modulations or severe materials corrosion.
High rotation speeds of both resistive materials (glass wafer and shield plate) can generate very high charging levels.
Indeed, the electrical field can affect the dipoles orientation and affect materials etch rate [5] [6].
Another neutralization method relies on materials photo ionization using relevant light wavelength.

Regional Science and Technology Innovation Level Evaluation Index System This paper based on the studied of assessment index system of paper [7].
However, if factors weights are different, fuzzy matrix operation is in need, then get the final result of fuzzy evaluation: In evaluation index system of university culture, the factors set hereis spiritual culture, is material culture, is behavior culture, stands for characteristics of the project.

R (the resistance of structural element) is the function of indicating mechanical property of member materials and geometrical relationship.
Failure mode of the members is similar to the proper reinforcement damage of the single-steel rectangle section beam, so the CFRP can maximize the performance of carbon fiber materials to improve the bearing capacity of members.
