The intensity of a ray of monochromatic light decreases exponentially as the concentration of the absorbing medium increases. 一束单色光的强度随着吸收介质的浓度增加而呈指数下降。
The reaction chronaxy of each monochromatic light and total reaction chronaxy of obese children were longer than that of controls. 实验组各单色光反应时值和总反应时值均长于对照组。
