The turbulent effects of plasmas in above spectral lines broadening have been calculated primarily. furthermore, as an example, the turbulent region scale that corresponds to the turbulent broadening value of fexiva5303 in corona has been calculated
進一步以日冕綠線f _ exiv 5303為例，計算了它的等離子體加寬值對應的湍動區尺度，發現與實際日冕尺度相符。 -
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。 -
From the past research work, it has been known that the main mechanisms of spectral lines broadening in the atmospheres of stars are doppler broadening, spectral lines broadening by rotation and expending, pressure broadening ( stark broadening ), natural broadening, spectral lines broadening in magnetic field, sonic waves and alfv e n waves broadening, etc. but it is not enough to explain the recent observation phenomena by above theories of spectral lines broadening
以往的研究已經判明，在恆星大氣內譜線致寬的主要機制是多普勒致寬、自轉源或膨脹源引起的致寬、壓力致寬（斯塔克致寬） 、自然致寬、磁場引起的加寬、聲波及阿爾文波致寬等。然而，已有的譜線致寬理論不足以解釋最近的一些觀測現象，仍存在觀測值與理論值之間的差異。 -
The historical retrospect of physical mechanisms of spectral lines broadening in stars is presented
本文對引起恆星光譜線加寬的物理機製作了回顧。 -
Thus, the nonthermal broadening in the stars " spectral lines above has been explained abstractly by the theory of spectral lines broadening in plasmas
因此，等離子體譜線致寬理論對以上恆星譜線非熱加寬給予了理論解釋。 -
So it is necessary to seek new theories to explain the spectral lines broadening of stars
這樣，尋求新的理論解釋恆星光譜線的加寬成為必要。
