| 摘 要： | 分别采用Holtsmark,Neutral Point,Nearest-Neighbor和Mayer模犁微场分布函数对Stark线型进行了研究,进而得到相应微场函数下的Stark加宽和频移,研究了4种不同的微场分布函数对Stark加宽和频移的影响.研究结果表明,在电子加宽参数不变时,4种微场分布函数对stark加宽和频移的影响随离子加宽参数的增加而增加;在离子加宽参数不变时,4种微场分布甬数对Stark加宽和频移的影响随电子加宽参数的增加而增加;特别是,当离子加宽参数较大时,Mayer模型微场分布函数对Stark加宽和频移的影响异常明显.这说明,微场分布函数对谱线的加宽和频移的影响在离子与离子碰撞剧烈的等离子体环境中尤其显著,在这样的等离子体环境中,进行等离子体诊断时,选择合适的微场分布函数非常重要.结果对等离子体诊断有一定参考价值.
