The possibility of manufacturing any torso product without creases and tears from a thin sheet made of plastic materials is theoretically proved.
In 1995 on the ХХХI Scientific Conference of the Faculty of Physic-and-Mathematic-and-Natural Sciences of the RUDN University, S.N.
It should be noted that parabolic bending with conservation of rectilinear generatrixes of torso products will be only under the condition of movement of two opposite contour straight edges along the trajectories calculated beforehand and that can be done with the help of the materials of a monography [13, p. 180].

Teaching facilities were either inadequate or out of date; course setups and teaching materials were old fashioned; teaching staff force was inadequate and a lot of teachers were overloaded with teaching assignments; in certain cases, some teachers did not prepare the lessons well and students had a lot of complaints.
The university set up “university student science and technology innovation fund” and carries out various kinds of science and technology competitions.

It will be helpful to save money for buying new products, backup and reduce the waste of energy, raw materials and outlay owing to management and stop running.
Remanufacturing technology and its application Materials failures, such as wear, corrosion and fatigue, usually occur on the surface.
Many key techniques applied in remanufacturing come from up-to-date achievement of science and technology such as advanced surface technique, micro and nano-coating and wear-resistance self-recovery material and technique, renovation heat treatment technique, molding technique of remanufacturing blank and up-date of outdated products.
The Ni-Al alloy coatings was chosed as remanufacting materials.
Acknowledgements The financial support for this work by the National Natural Science Foundation of China (Project No. 50901089) is grateful acknowledged.

The surface properties of UHWMPE and metal are very different, so it is more difficult to improve the bonding strength between the two materials.
EXPERIMENTAL Materials Chloroprene rubber A-90 (CR) was provided by Japan NEC Chemistry.
In addition, the main chains of CR/MMA rubber have both polar groups and non-polar groups, thus it has a strong adhesive force to polar and non-polar materials.
