Meanwhile, the difference in thermal conductivity of underlining materials (plastic sheet, steel sheet and aluminium plate) has little effect on the etching rate.
研究还发现，不同垫层（塑料片、钢片和铝板）导热性能对刻蚀速率影响很小。

The team started by etching thin layers of brass on plastic film, which could be sewed onto a fabric.
研究团队首先在塑料胶卷上蚀刻多层薄的黄铜，这些塑料胶卷能够被缝合在布料上。
