The averages of IF per year ranged from 0. 768 to 2.206.The original articles selected by SCI were totally cited 38 times. Every article was cited 1.41 times in average.Of all 275 papers,each had an average of 9.8 citing reference, increasing from 8.1 in 1999 to 12.0 in 2003.About 80.7 % of those references were written in foreign languages.The Price's index of those papers was 43.2%.Conclusions The number of papers kept improving in the past 5 years, and had a significant improvement in 2003.The authors showes great talents to use English articles as their main information sources.
