摘　　要：DDX is one of the most important nuclear data used in nuclear engineering,particularly in design of nuclear device and neutron shielding. The experimental data is not only necessary for nuclearDDX is one of the most important nuclear data used in nuclear engineering, particularly in design of nuclear device and neutron shielding. The experimental data is not only necessary for nuclear engineering design, but also important for the study of nuclear reaction mechanism and for checking and improving nuclear reaction models as well. Beryllium has been considered as an important nuclear material in nuclear engineering, it often serves as the neutron multiplifier in fusion reactors because of the relatively large （n, 2n） reaction cross section, low mass and low neutron-capture cross section. Therefore it is very important to study the DDX experimentally for beryllium.
