The visible light absorption curve and heat recovery curve of mercuric and zinc dithizone in PMMA and PS are also measured.

测定了两种金属双硫腙在聚合物介质中的基态及激发态可见光谱吸收曲线，及其在黑暗环境下的热回复曲线。

PS, PMMA, SAN) were studied. The results show that filling ROF in small amount to ductile PVC matrix leads apparent improvement of impact strength while tensile strength and modulus increase slightly.

实验发现将少许ROF 填充到硬聚氯乙烯韧性体中，能使基体的冲击强度和拉伸强度同时提高，获得既增韧又增强的双重效果。

With increasing content of the scattering additive substance, the size of PS particles dispersed in the PMMA matrix increased and the extent of distribution decreased.

随着添加物用量的增加，分散在PM MA基体中的PS的粒径增加，分布的密度减少。
