用标准σ－ω混合方法所构造的介子介电函数，计算了核物质中σ，ω介子的集体激发能谱（或色散关系），并考虑ρ°－ω混合的效应，结果表明ρ°－ω混合对色散关系的影响很小。

By using meson dielectric function constructured by standard σ-ω mixiingmethod

we calculate the collective excitation spectra(or dispersion relation)ofσ

ωmesons in nuclear matter

The ρ°-ωmixing effect on the collective excitation is studiedand the mixing effect on σ

ω dispersion relation is found small.
