英文摘要	The two-photon exchange corrections is crucial to reconcile the discrepancy of the form factor ratio caused by different measurement techniques. We estimate the two-photon exchange corrections to some electromagnetic observables of electron-nucleon scattering in a light cone quark model. The two-photon exchange corrections to the differential cross section are strongly dependent on the kinematic factor, which is consistent with the results from other model. We further extend the two-photon exchange corrections to time-like region and find the two-photon exchange corrections to differential cross section is very small in low center-of-mass energy region, but the corrections to polarization observables are relative large.
