Scaly textures in a veneer of nitrogen frost bore witness to patterns of sublimation and deposition, as the thin atmosphere breathed through cycles of expansion and collapse.
氮霜，鳞纹理板，孔，是对升华和沉积模式的见证，由于稀薄的大气通过循环的扩张和崩溃。

As to evaluation feedback, bore in mind, the effectiveness of in-class tests can not be overlooked as well as the expansion and enhancement of knowledge in designing process.
测评反馈部分的设计要注意当堂检测的效度，还要兼顾到拓展与提高。
