Rough surface is easy to generate V shape of stress concentration, which reduce fracture strength.
粗糙表面的晶粒间易产生V形口，导致应力集中，降低了膜的断裂强度。

With CO_2 concentration increased, negative effects on corn seed rough protein, rough fiber and contents of total carbohydrate were observed but the starch of corn was positively effected.
2浓度增加，对玉米籽粒粗蛋白、粗纤维和总糖含量的影响呈负效应，对淀粉的影响呈正效应。

The coating is split and rough owing to the cellulose, so the problem can be solved by adjusting the proportion of coating particle and controlling the sduble silicate concentration.
