The results showed that with the increase of nitride partial pressure in the range of 2. 0～8. 0×10〓Pa, the hardness of NbN, TaN single layer films decreased, but the hardness of TiN films kept unchanged. The crystal structure of TaN films changed from the mixture of tetragonal β-Ta and faced-center cubic δ-TaN to hexagonal TaN and that of NbN films from FCC δ-NbN to hexagonal ε-NbN. The crystal structure of TiN films is FCC in all the range of partial pressure researched.

Magnetotelluric field finite difference migration tomography Found on the researches of Zhdanov etc. in MT finite difference migration tomography, we analyze and summarize both fruits and limitation of foregone peoples' achievements. So more precise finite difference extrapolation equation can be deduced, and it can be easily applied into the migration tomography. New equation reserved the derivative terms of wave number both at vertical and horizontal direction, so that more exquisite geoelectric diversification can still be accommodated, that is the very requirement of practical data interpolation.
