Adopting the strategy to search in name space and version space separately, this paper also presents backward inheriting path-finding mechanism in version space.

The integrations of vertical inheritance from the local literatures and horizontal reference to the literatures of various nations and races make up the driving force behind the literature evolution.

Based on the analysis of the measuring block,the loading block,the structure scheme and the selection of sensor,DWS ultraprecision(NANO-grade) vibration displacement measurement instrument and automatic data gathering tech are adopted to develop a new type of test table for testing the performances of gas dynamic and static pressure radial bearing.

This paper analyzes the reasons for the burning of the front radial bearing of the generator turbine Y 1701,presents the solutions for modification and the final effects.

This paper introduces a design process of a testing stand for aerostatic journal bearings.

The methods to improve the stability of hydrostatic gas journal bearings through enhancing the damp of rotor-bearing system were reviewed.

A new type of tribometer for experimental study of tribological performance of journal bearings under micro-load was established,which utilizes the method of load counterpoise to obtain mechanics equilibrium state of the test rig so as to apply load from zero.

To analyze the effects of non-Newtonian lubricants to the journal bearing lubrication under the condition of dynamic load,a modified Reynolds equation was derived.

In order to develop a new type of journal gas pressurized journal gas bearing through enhancing the damp of rotor-bearing system,the performances of rubber rings supported gas journal bearing with orifices of tangential supply were discussed.
