With the increase of UV exposure, the resonance wavelength shifts toward longer wavelength and resonance peak intensity increases first and then decreases.
随着曝光量的增加，其共振波长向长波方向移动，共振峰强度先增大继而减小。

The results of numerical simulation show the lesion of photoaging skin can be selectively damaged if the wavelength, exposure duration and exposure dose of irradiated ligh are reasonably selected.
"We don't know the dose of photosynthesizer needed, the proper wavelength of light, the amount of area to be exposed, or the length of light exposure, " he said.
