摘要
本文收集了NGC4151近90年的光学资料，并用Jurkevich分析方法对其进行了光变周期分析其光变存在一个14．04±0．8年的长周期，且该天体的谱型与源的亮度强烈相关。
In this paper, the optical data from available literature have been compiled and used to infer the possible periods of variation by means of Jurkevich' method, and a period of about 14.0 years has been found. Besides, a strong correlation between brightness and colour index has been discovered.
