摘要：

The hadronic photon structure function F-2(gamma) has been measured in the Q(2) range from 4 to 30 GeV2/c(4) and down to x values of order 0.001, using data taken with the DELPHI detector at LEP between 1991 and 1993. A comparison is made with several F-2(gamma) parameterizations with special emphasis on their low rr: behaviour. A result on the Q(2) evolution of F-2(gamma) is presented.
