Survey the whole process of Chinese cyber literature which stand firm in the mainstream of Chinese literature gradually,experiencing the stage of preparatory rising,the stage of moderate prosperity and the stage of realignment.

The Analysis of Blisk-tunnel NC Machine Based on UG Secondary Development;

In order to improve the stability of slot rough machining for open blisks,the ruled surface was used to approximate the freeform blade surface,which can reduce the computational complexity of slot rough machining for open blisks with freeform blade surfaces.

The drawing,forging roughcast, mold's structure and isothermal forging's technology of TC17 alloy blisk are studied .

Describes the principle of flatness filter carrousel,the maintenance method of relevant doubtable failure points,some matters to use multi-meter and solid state relay by means of a case of troubleshooting for a uncommon failure.

4500kW brushless exciter is the device which supplies the direct current for 1000MW level turbine genera- tor,among the manufacturing technology of 4 500kW brushless exciter,the diode rectifying is very important part,assuring the good contact between the rectifying components and rectifier wheel is also very important .

With a domestically-made 660 MW supercritical steam turbine generator unit serving as an object of study,the torsion rigidity of shafting specific structures(such as stepped shaft,wholly-wrought wheel disks) and its effect on torsion vibration were calculated and discussed as a major focus.
