The paper introduces producting technology of hot rolling high strength double-faced enamelled steel,study on mechanism how to realize properties of double-faced enamel and high yield strength.

Using double-side grinding technology in 300 mm Si wafer manufacturing process,the Si wafer can obtain high accuracy surface parameters,and generate obvious grinding marks,which can affect the surface flatness.

Considering that the fabric of computerized knitting machine is characterized by double-faced jacquard at present,the program based on multi-views is set forth to raise designing efficiency.

Based on the analysis of the process of double-sided polishing,we establish a mathematical model when the double-sided polishing machine working in a calm movement state,simulate the process of double-sided polishing by programming language as changing the parameters.

The wafer motion and the load in double-sided polishing process are main factors which affect the wafer surface quality.

According to the characteristics of core,clad and solid rim glass material of microchannel plate(MCP),the mechanism of double-sided polishing of MCP was analyzed.

The design principle of stitched reversible fabric;

Spinning processing of regenerated bamboo fiber,knitting and dyeing processing of reversible fabric of regenerated bamboo,single-side intertexture fabric of regenerated bamboo and Lyca were introduced.
