摘要
本论文研究了2，4─—二羟基苯甲酸甲酯（简称D）的紫外吸收及与苯乙烯共混物的抗紫外降解性能，从荧光发射和荧光激发角度探讨了其能量转移效应。
In this paper we have studied ultraviolet-absorption properties of 2, 4-dohydroxylmethy benzoate and ultraviolet-degradation properties of its co-polymer with styrene. Also wehave probed effects of energy transfer from the aspects of fluorescence emission and excitationspectra.
