The resulting "frozen smoke" aerogel is flexible and has conductivity that makes it an ideal sensor.

用这种方法得到的“固体烟”气溶胶有良好的弹性和导电性，正是理想的制造传感器的材料。

Aerogel is nicknamed "frozen smoke" and is made by extracting water from a silica gel, then replacing it with gas such as carbon dioxide.

气凝胶的一个绰号是“固态烟”，通过从硅胶中抽去水分代之以气体(比如用二氧化碳)制成。

Contrary to the "gel" part of its name, aerogels are highly porous solids that look like frozen blue smoke.
