摘　　要：The precipitate patterns were studied in rare earthcholate diffusion systems. The corresponding precipitates were characterized by Forie Transformed Infrared(FTIR) and Extended XRay Absorption Fine Structure(EXAFS) spectroscopy. The experimental results indicate that rare earth ions tend to produce periodic precipitation, and the pattern precipitates are just the corresponding rare earth cholate complexes.The precipitate patterns were studied in rare earthcholate diffusion systems.
