[求助] 求幾句話英語翻譯

首先用stober法制備SiO2微球再以溶膠-凝膠法制備SiO2/TiO2復(fù)合物，并以亞甲基藍(lán)為染料，探索了二氧化硅的顆粒大小與焙燒溫度對復(fù)合物吸附效果和光催化活性的影響。結(jié)果表明：SiO2顆粒越小，吸附活性越好；實驗還發(fā)現(xiàn)：染料在催化劑表面的吸附是影響催化劑光催化活性的重要因素,吸附越好催化活性越差；還發(fā)現(xiàn)還發(fā)現(xiàn)取樣時間較早時，焙燒700度吸附效果最好，4h取樣時，1000度效果最好。

First，by the Stober Method，SiO2 microspheres were prepared，and then by the Sol -Gel Method，SiO2/TiO2 compounds were prepared again. With methylene blue as the dye, the impacts of the silica particle size and calcination temperature on the complex adsorption effect and photocatalytic activity were explored.The results showed that the smaller the particles of SiO2 were, the better the adsorption activity were.It was found in the experiment that the dye adsorption on the catalyst surface was an important factor to affect the photocatalytic activity, and that the better the dye adsorption was,the worse the catalytic activity was .Fnally,it was also found that the earlier the sampling time was, the better the effect calcined at 700 °C adsorption,and that the best effect was sampling after 4h and 1,000 degrees.
