The results in- dicated that the minimum or maxmum of positive rate of tuberculin test in girl students were more higher than that in boy students respectively no matter where they came from countryside or for- est region and pastoral area. Significance deviations testified by t-test exist between them, no sig- nificance deviations between girls and boys students who came from city and town.
