2Zr and V2(Zr0.5 Hf0.5)". This means that for these superconductors the elastic softening plays a role in enhancing Tc to some extent. It seems that between V2Zr or V2Hf and V2(Zr0.5 Hf0.5) there exists essential difference, which makes Tc increasing and the phonon frequencies softening for the formers while Tc decreasing and the phonon frequencies slightly hardening for the later after adding small amounts of Nb or Ta. It can be considered as the result of hybridzation of conduction bands, which is studied by means of the LMTO (linear combination of muffin-tin orbitals)method."/>     Ta对C—15相V<sub>2</sub>Hf和V<sub>2</sub>(Zr<sub>0.5</sub>Hf<sub>0.5</sub>)系列声子性能的影响
