费希纳颜色效应是一个很知名的视觉现象，是指转动分布着黑白相间条纹的圆盘( 贝汉转盘) 能够看到彩色环的现 象，它的形成原因目前仍未有定论. 本文对费希纳颜色效应进行了实验探究，在对贝汉转盘进行改进的基础上，从光源、转速、 条纹宽度等方面着手，对费希纳颜色效应的现象和规律进行了量化研究，对其成因进行了适当推测.

The Fechner color effect is a well - known visual phenomenon. When one sees a rotating turntable which with some black and white patterns on it such as Benham's top，one will see several other colors. The cause of its formation is still inconclusive. We analyze the phenomenon，improve the Benham's top，and make some experiments. Quantitative experiments are performed on aspects of the light source，rotational speed，stripe width and so on.
