1. The momental equation and characteristic curves of a hydraulic coupling are given. The problems which are paid attention to in use and maintenance are pointed out.

2. The statistics momental analysis method was applied to compare with the traditional compartment model.

3. Green-pressing density, simulated green-pressing strength and bonding momental of high frequency brazing were assayed.

4. The permanent-magnetism frequency-conversion momental motor used for a lathe is in the drawing.

5. Bill Clinton's first 100 days will be filled with momental battles over the budget deficit and health care reform.

6. This paper carries out the thorough analysis and research to the momental load simulator by means of electro hydraulic servo control to realize loading.
