| 摘 要： | 本文讨论了最近西欧中心的LEP关于轻中微子个数N_7的实验结果对大统一前子模型的限制.由于LEP的精确实验结果给出N_y=3,可能的大统一前子模型为禁闭弱作用大统一前子模型.我们也讨论了若允许重中微子代存在时,LEP实验结果对大统一前子模型的限制.

| 关 键 词： | LEP 中微子 禁闭弱作用 |

| Abstract: | Constraints to grand unified prdon models from recent LEP data about light neutrino species N, are analyzed, Because of the precise experimental results prefer N_v= 3, the possible models are grand unified prdon models with confining weak interaction. We also discuss the constraints to grand unified preon models if the very heavy neutrinos are allowed. |
