Abstract：
Numerical reasults are presented for the photoproduction of twojets via resolved quasi-real photons at HERA in next-to-leading order(NLO) QCD. It shows that the NLO contribution is about a factor of 0.5 to 1 of the LO contribution. This may provide an explanation to the ZEUS results: "the LO QCD results is below data a factor of 1.5 to 2". When the invariant mass of two-jet system is not too large, say less than 30GeV, the cross section is dominated by the photon gluon distributionin.This may be used to measure the gluon structure of photon. When the invariant mass of two-jet system is larger, say than 30GeV, the cross section is dominated by the photon quark distributionin. This may be used to measure the quark structure of photon.
