| 摘 要： | 本文提出一个能统一描述多种谱线轮廓的新函数。它能准确地包括洛伦兹线型函数和双曲正割函数,并可逼近高斯型函数和佛克脱线型函数。此外,它还能描述有兰姆凹陷的谱线及非对称的单峰、双峰谱线。

| Abstract: | A new function of spectral line shapes is represented. It includes Lorentz line shape function, hyperbolic secant (sech) function and approxinmates to Gaussian function and Voigt line shape function. Besides this, it can describe not only the line shape with a Lamb dip but also describe unsymmetical single- peak and double-peak line shapes. |

| Keywords: | Lorentz Gauss Voigt line shape Lamb dip line shape |
