摘　　要：电子的电磁质量构成仍是物理学中一个悬而未决的问题,一般认为电子的电荷分布具有球对称性。由于球对称分布的电荷体系在其运动时的电磁场的相对论能量-速度关系完全不同于相对论(机械)质量-速度关系,那么运动电子的相对论总能量不仅是其速度的函数,也是其电磁质量与已知的电子静质量的比率的函数。基于以上认识,该文采用Bertozzi实验来研究电子的电磁质量,并对这一方法进行了初步的尝试,对电子的电磁质量给出了一个具有一定参考价值的定量结果。The electromagnetic mass of the electron remains yet to be an open question in physics. The classical model of the electron consists of a spherically symmetric distribution of electric charge. Because the relativistic electromagnetic energy-speed relation for spherical symmetric charge distribution is completely different from the relativistic（mechanical） mass-speed relation,the total relativistic energy of the electron in motion is not only a function of its speed,but also a function of the ratio of its electromagnetic mass to the known rest mass of the electron. In this paper,basing on the above mentioned knowledge,it was suggested that Bertozzi’s experiment should be used to research for electromagnetic mass of the electron,and the method was applied tentatively.
