摘要：
We study the virtual photon structure functions frond gauge/string duality. If the Bjorken variable x is not small, supergravity approximation becomes good in dual string theory. We calculate the virtual photon structure functions at large 't Hooft coupling in a moderate x-region and determine x-behavior of the structure functions. We also show that the Callan-Gross relation F-L = 0 is satisfied to a good approximation in gravity calculation.
