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 本文從等離子體波與波相互作用觀點出發,由高頻電磁波輻射轉移方程導出了引起譜線寬度變化的偏微分方程,編寫fortran程序求解偏微分方程的數值解,具體計算了日冕綠線f _ exiv 5303和夫朗禾費線3704 、矮新星oycarf _ eii 4923 . 9 、天琴rr型變星f _ ei 4934的譜線加寬值,對以上各譜線加寬中的等離子體致寬效應作了初步計算。
