求翻译：但如果聚合物浓度继续增加，则会阻碍光照到二氧化钛表面，反而会降低复合微粒对可见光的吸收。质量比为1：5的复合微粒之所以在可见光区有较高的吸收，是由于聚合物浓度太高，聚合物本身起了主要作用。是什么意思？

However, if the polymer concentration continues to increase, it will hinder the light to the titania surface, but will reduce the absorption of visible light composite particles. Mass ratio of 1:5 composite particles have been higher in the visible region the absorption is due to the polymer concent

But if the polymer density continues to increase, then can hinder the illumination to the titanium dioxide surface, instead can reduce the compound particle to the visible light absorption.The mass ratio is 1:5 compound particle the reason that has the high absorption in the visible light area, is b

However, if the polymer concentration continues to increase, it will obstruct the light to the titanium dioxide surface, it will reduce the absorption of composite fine particles on the visible light.
