Factors that influence the performance of metal wire-mesh filters are summarized in this paper to give some recommendations for the better operation of the filter.

The paper first introduced the method of shielding test of metal wire-mesh screen , then analyses the influence to testing results by the two different size of testing windows .

Structural characteristics and functional mechanisms of metal mesh filtration technology were introduced in this paper.

Metal mesh,a common shielding material,is chosen to be measured in this paper in order to get some data and conclusions,which can narrate the value of practical applications of shielding technique.

The present experimental investigation attempts to understand the suppressing effect of metal mesh construction on deflagration waves of premixed ethyne air mixture in unconfined space.

Design experiment: testing uhe mechanical properties of metal wire;

Based on the requirements of the flexure test on angel control and cycle control in the process of bending of metal wire,combine with PLC control technology, high- performance and fine- segmentation driver as well as step- in motor.

In this dissertation, we study the electron transport in THz QCL, compare and discuss the waveguide property, and investigate the propagation property of THz metal wire waveguide.
