The outcome show:1. The increasing number of the articles about the internet addiction is linear pattern, the correlation of the article's number and years' number is very significant.2. The study about the internet addiction is all over the country .Among the published articles ,Shang hai accounts for the most, the number of the articles in Jiang su , Hu bei, Shan dong is 37, 29, 28 . But the number of the articles in Yun nan , Gui zhou, Xin jiang is only 1. It may be related with the development of the economic ,the number of the university students and the prevalence of the internet.3. Among all the relative articles, the normal articles account for the most , the number is 422. The second are the master and doctor' articles and the nuclear journal.4. Among all the relative articles, the fist author who is from universities and scientific institutes account for 67.1%, from hospitals and mental health centers account for 11.1%, from middle schools and vocational colleges account for2.8%. The outcome shows us that the number of the articles from the universities and scientific institutes is remarkable more than other departments.5.

Different sexes universities' IAD ratio have remarkable difference (Z= -6.777, P <0.01); the effect size is 0.348, which lies in middle level.8. Different grades(from junior to senior) universities' IAD ratio have remarkable difference (Z= -9.847, P<0.01 ); the effect size is 0.119, which lies in lower level.9. In SCL - 90, the interpersonal sensitivity factor between IAD and NIAD has not remarkable difference (Z=2.424, P>0.01 ); but the factors such as somatization , obsessive_complusive , phobia anxiety, the two groups has remarkable difference,(P<0.01,Z=2.442-5.873 ). among the nine factors ,only the obsessive_complusive factor's effect size is about 0.8 which lie in higher level, but the anxiety and the depression factor's effect size is about 0.2 which lie in lower level.Conclusions The increasing number of the articles about the internet addiction is linear pattern , among the published articles ,Shang hai accounts for the most, the second is Jiang su ,Hu bei ,Shan dong, the least is Xin jang . And the normal articles account for the most , The second are the master and doctor' articles and the nuclear journal. In addition , the fist author who is from universities and scientific institutes account for 67.1%, from hospitals and mental health centers account for 11.1%, from middle schools and vocational colleges account for2.8%.
