Some defects exist in the Surface dense layer.───表面致密层存在有缺陷。

During the reduction process, it is possible to obtain metal with dense layer or ultrafine powder by controlling the reaction temperature and chloride concentration.───在还原过程中，控制反应温度及氯化物浓度可以获得金属致密镀层或超微粉末。

The outer porous layer is damaged after corrosion, while the inner dense layer played a key role to protect the coating from corrosion.───经一定的腐蚀时间后，微弧氧化陶瓷膜的多孔层最终遭到破坏，而紧密层对防腐蚀起着至关重要的作用。

The planet was, in fact, very near the horizon and was traversing a dense layer of mist which imparted to it a horrible ruddy hue.───那颗行星当时离地平线确是很近，透过一层浓雾，映出一种骇目的红光。
