Generally, the film quality of octadecanoic acid L-B films may be judged by the link between the attenuation of X-P S peak strength and film thickness. during this paper, the angular resolution X-P S technique is employed to see the

As a catalyst, niobium chloride plays an important role in organic synthesis. Most of the reactions catalyzed by niobium chloride have reaction strips. In addition, pentachloride has the advantages of mild, short time, high yield, less catalyst consumption, simple operation,
