摘　　要：在重电磁场理论背景下,探讨了用激光通过强磁场探测轴子的高精度实验中光子静质量效应的大小和影响,并与调制扭秤实验给出的光子静质量限作比较.结果表明:此类实验中光子静质量效应对轴子质量限的影响很小;实验给出可能的光子静质量限mγ<1×10-3eV,精度远小于调制扭秤实验给出的光子静质量限精度,扭秤实验仍是目前检测光子静质量的有效手段.From massive electromagnetic field theory, the level and effects of the photon rest mass in high-precision experiments to search for the axions by using the laser beam traveling trough a strong magnetic field were explored. The results were compared with the limits of photon rest mass＇ presented by using modulated torsion balance. It shows that the photon rest mass in such experiments has very little effect on the mass limit of axion, and the sensitivity of the implied limit of the photon rest mass mγ〈1×10^-3 eV is also poorer than the limits presented by using modulated torsion balance. It is conclude that the torsion balance is still an effective measure to detect the photon rest mass.
