radiation-induced decomposition

Effects of UV-B Radiation on Litter Decomposition and Mechanism

UV-B辐射对植物残体分解的影响及其机理

The results show that the rate of decomposition increases with the lengthening of radiation time, the rate of decomposition increases with the increasing in temperature under 60 degree centigrade and the rate decreases with the increasing in temperature above 60 degree centigrade.

结果表明：DBS的降解率随辐照时间的延长而增加；溶液温度在低于60℃时，DBS的降解率随温度的升高而增加，高于60℃降解率随温度的升高反而降低；

The radiation decomposition of the sample is mainly the rupture of C C bond, and less is the rupture of C F bond.

材料的辐射降解主要发生在主链上，即C C键断裂，而侧基C F键的断裂相对较少。
