在氮气和空气中退火时，随退火温度升高前者表现为红移而后者表现为蓝移，这归属于量子尺寸效应。
The optical absorption edges red-shift along with the increase of annealing temperature under nitrogen and blue-shift under air were observed, which can be attributed to the quantum size effect.
另外，对碳化硅薄膜的退火处理大多是在真空、空气、氩气或氮气气氛下进行。
In addition, the annealing process of SiC films is mostly carried out in vacuum, argon gas or nitrogen gas ambience.
利用钢卷退火温度曲线以及煤气和空气消耗量曲线，得到了单台罩式炉退火过程中的抽风量变化曲线，在此基础上，得到了系统抽风量。
According to the curve of rolled coil annealing temperature, the curve of gas and air consumption, the air volume for one batch annealing furnace and discharge flue gas system are obtained.
