A simple criterion is derived in terms of molecular parameters to determine whether collisional narrowing is of importance in determining the equivalent widths of spectral lines of any combination of emitting and broadening gases. The criterion is verified by numerical integration, and a simple formula is given for the maximum error obtained when the Voigt profile is used as an approximation to the Galatry profile.
根据分子参数推导了一个简单的判据，以确定碰撞变窄在决定任何发射气体和增宽气体组合的谱线等效宽度时是否重要。该判据通过数值积分得到验证，并给出了一个简单公式，用于计算当用沃伊特轮廓近似加拉特里轮廓时所产生的最大误差。
