摘要：
The corrections of two-photon exchange on deuteron electromagnetic form factors are estimated based on an effective Lagrangian approach. Numerical results for the form factors G(C,M,Q) of the deuteron with the corrections are compared to its empirical ones. Moreover, the two new form factors, due to the two-photon exchange, are analyzed. A possible way to test the two-photon exchange corrections to the deuteron form factors is discussed.
