Based on the viewpoint of interaction between waves in plasmas , the partial differential equation that causes the spectral lines broadening has been deduced from radiation transfer equation of high - frequency electromagnetic waves in plasmas . the numerical solution has been obtained by using the fortran program we compiled . we concretely calculated the spectral lines widths of and fraunhoferx 3704 in corona , fj / a4923 . 9 in dwarf nova oy car and f . / a4934 in the variable star rr lyrae 本文从等离子体波与波相互作用观点出发,由高频电磁波辐射转移方程导出了引起谱线宽度变化的偏微分方程,编写fortran程序求解偏微分方程的数值解,具体计算了日冕绿线f _ exiv 5303和夫朗禾费线3704 、矮新星oycarf _ eii 4923 . 9 、天琴rr型变星f _ ei 4934的谱线加宽值,对以上各谱线加宽中的等离子体致宽效应作了初步计算。
