自从前苏联的V. Lubimov（1980年）和瑞士苏黎世大学的W. Kundig（1986年）发表了关于中微子质量的研究以来，进一步的工作已在日本等国展开；现在有一批实验室在进行中微子研究。文章论述了两个关键问题，即光子与中微子的相似性和令人感兴趣的超光速中微子理论。

Work on neutrino's mass has been going on in Japan and several other countries since the early work of V. Lubimov in USSR inl980 and that of a work with W. Kundig at Zurich University inl986. At the present time, there are several laboratories concerned with the research aspects of such particles. It among the advances of all sorts of neutrinos, two main cruxes should be considered for this subject. One is that the similarity between the photon and the neutrino, the other is that the very interesting superluminal theory for neutrinos.
