The numbers of clusters made up of 1551 and 1541 bonded pairs representing the non-crystal structure occupy predominate position and the small numbers of clusters made up of 1431, 1661 and 1441 bonded pairs coexist in the non-crystal system at 4×10〓K/s cooling rate, thus there exist a large number of icosahedra clusters in the non-crystal system. The numbers of clusters made up of 1421 bonded pairs corresponding to the fcc-like structure occupy predominate position and the small numbers of clusters made up of 1422 and 1551 bonded pairs coexist in the crystal system during the 4×10〓K/s cooling process, thus the system can form the regular fcc-like structure.

在4×10〓K/s的冷速下，标征体系非晶结构的五重对称键型1551和1541所形成的小团簇数量在非晶体系中占主导位置，同时还存在少量的1431、1441和1661等其它键型形成的小团簇，这样，体系中含有大量的二十面体团簇结构；在4×10〓K/s的冷速下，标征面心立方结构的1421键型所形成的小团簇数量在晶体中占第一位，同时还存在一定量的1422、1441和1661等其它类型的键对所形成的团簇，体系最终形成面心立方结构。

As caustic solution prewashing of FCC gasoline discharges lots of lye, it is nec essary to improve the process. The solid base pretreating of FCC gasoline wil l completely avoid this problem.

用苛性碱液对汽油进行预碱洗时易产生大量废碱液，为彻底消除废液提出了用固体碱预处理代替苛性碱液预碱洗的方法。

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.

研究结果表明：在2.0～8.0×10〓pa的氮分压之间，随氮分压的升高，TaN和NbN薄膜硬度下降，而TiN薄膜的硬度值不随氮分压的变化而变化；TaN薄膜的相结构由低氮分压时的正方β-Ta和面心δ-TaN所组成的两相混合物过渡到六方TaN结构，NbN薄膜则由面心立方结构的δ-NbN逐渐过渡到六方结构ε-NbN，而TiN薄膜的晶体结构基本不随氮分压的变化而变化，均为面心立方结构。
