Abstract：
Some properties about the effective boson charges are discussed in term of the neutron-proton interacting boson model.The effective boson charges of some U(5)-like and O(6)-like nuclei are extracted from the experimental data of electromagnetic transition probabilies.With the calculated effective boson charges the electromagnetic transition probabilities of the mixed states in the nuclei are calculated,too.It shows that the effective boson charges both of neutron and proton have something of screening effect.
