The research indicated that the main electric particles forming guiding discharge channel were the electrons released from the process of the breaking up of the negative ions. During 10 microseconds after the laser pulse, the electrode also could guide discharge effectively; and it suggested the new conception of the electrode erosion, and developed new-type running disk electrode, which could discharge for a million times in atmosphere. It also suggested methods of the texturing roller of besmearing with oil film and cathodal discharge in processing. The research of the texturing roller indicated that roughness of 14 microns and the intensified depth of over 200 microns could be got.

The results show that there are many differences in the static characteristics of the rotor in large gap annular flow and that in bearings and seals, and the wall friction coefficient changes circumferentially. The results also show that the wall roughness and the eccentricity ratio have considerable effects on the static characteristics in large gap annular flow.
