Key factor influencing on the development level of our printing machine industry;

The reason was analyzed that fall behind the international advanced level in domestic printing machine for a long time.

By virtue of the advantage of CBR technique in knowledge obtaining and understanding,combin ing the characteristic of printing equipment,introduces the CBR technique into the faulty diagnoses field of printing machine,studies the principle and method of CBR technology,discusses the implementation process about CBR technique ap plied in printing equipment fault diagnosis system.

By looking into the features of the latest models of printing presses, mainly offset, the developing trends of printing machinery in the nineties are discussed.

This paper systematically sums up the reverse design of the cam mechanism in the printing machinery, and develops the software of the computer-aided reverse design.

Study on the scour mechanism of sandy seabed below submarine pipelines;

It seems that conducting the study on scour mechanism of "riverbed rolling up" phenomenon caused by hyper-sediment concentrated floods under the conditions of remarkable reduction of water volume and increasing serious situation of the withered and silted channels of the Yellow River, has not only an important academic value, bu.

Effect of viscous heating on hot-spot formation of particulate filled propellant under the mechanical impact load;

Cotton fabric strength affected by oxidation from detergent and mechanical impact during laundering

Mechanical fault analysis reveals that the possible causes of the problem can be narrowed down to the high spindle torque generated by the mechanical impact when a bar enters the roll bite.
