Abstract: The fuzzy numerical value analysis method is adopted for the first time, which solves the problem of nanometer electro-thermal in filming process. The key technique is embodied by controlling the time distribution, temperature and press in the filming process. The concrete technique of filming is showed by establishing the fuzzy mumbership function of above three indexes, which improves the precision of the materials of nanometer electro-thermal in hot-working. At the same time, the principles of the fuzzy relationship mapping inversion (FRMI) is put forward. Therefore, the standardization and continuity can be met.

Key words: fuzzy control, FRMI (fuzzy relationship mapping inversion), nanometer electro-thermal
