Anionic organic polymer flocculants are acrylic acid, sodium polyacrylate, polypropylene calcium and alkaline hydrolysis of polyacrylamide material and other polymers.
There are many results coming out.Acrylamide graft copolymer，as a cheap, abundant, renewable natural resources，can be added within the structure of polyacrylamide，and partially replace the more expensive synthetic materials, and reduce the cost of the product greatly.

Enterprise education curriculum is not standard, normative and systematic enough, which is mainly reflected in low status, no curriculum system and insufficient teaching materials.
University enterprise education only includes curriculum arrangement, teaching content and class hour arrangement etc, with no supporting enterprise teaching materials, few hours for enterprise education curriculum, lack of enterprise education activities and enterprise education practice platform etc.

At the beginning, analysis of the damping properties of structural materials was carried out.
Structural materials were chosen because of them the boring bar body has to be manufactured.
As a comparison materials Steel 45 and Steel 40Cr were selected.
