TEM observation showed that the center of the adiabatic shear band (ASB) was composed of recrystallized nano-grains (about 30-70 nm in diameter).

TEM观察表明绝热剪切带(asb)中心区域由30 - 70纳米的等轴晶组成。

Based on plenty of experiment data and analyzing results, we made several one-dimensional photonic crystals used in visible light and near infrared light which have band gaps from ten to a hundred nm.

根据大量的实验数据和分析结果，我们镀制出可见光区和近红外区的一维光子晶体，禁带分别有几十到一百纳米。
