Abstract
The effect of the evolution of partons in nuclear environment to the structure function of nucleons bound in a nucleus is investigated. Together with the nuclear shadowing effect caused by the spatial overlap of partons from neighboring nucleons in the nucleus in the small x region, the ratio of the average nuclear structure function of nucleus ~(56)Fe to the deuteron struc- ture function is calculated and a good agreement between the calculated results and the ex- perimental data is obtained.
