It's basically transparent, and extremely strong, nearly as hard as sapphire, so aluminum oxynitride is really useful for things ranging from bulletproof windows to super-durable camera lenses.

它基本上是透明的，而且硬度很高，几乎和蓝宝石一样坚硬，所以氮氧化铝被用于防弹玻璃、超耐用相机镜头等。

Total emissions of chemical oxygen demand and ammonia nitrogen will see an 8-percent drop, and that of oxynitride and volatile organic compounds will be reduced by more than 10% from 2020 levels, said the plan.

化学需氧量、氨氮、氮氧化物、挥发性有机物排放总量比2020年分别下降8%、8%、10%以上、10%以上。
