abstract="An analysis of the occupational trauma cases in 8 enterprises of Changping county showed that the over-all trauma rate was higher among the workers of the mechanic process (3.85%). The trauma cases among the mechanical workers were 74.2% of the total trauma cases. The common site of trauma was the four limbs (75.0-82.0%). The trauma occurred more frequently in the last two hours of the 8 working hours (205/438, 46.8%). A statistical analysis on the periods of three curves of the body bio-rhythm (e.g; physical, sentiments and intelligence curves) revealed close relationship between the occupational trauma and the period of the body bio-rhythm.<p /> <p>Language: zh</p>",
