A rotating cylinder photocatalytic reactor was designed and assembled,and the measurement of illumination distribution,as well as the degradation experiments of 4BS dye solution in batch operation were performed.

The illumination distribution on a horizontal plane of the plant culture shelf in the laboratory was analyzed.

Based on this principle , illumination distribution measurement experiments of flashlight cast system are done.

Effects of modifying between light distribution,yield and quality of different shapes on "Red Fuji" apple;
