气凝胶
AerogelA highly porous, low-density solid material derived from gels in which the liquid component of the gel has been replaced with a gas. The gel's solid network forms the structure of the resulting aerogel, resulting in extremely low thermal conductivity. / 一种由凝胶衍生而来的多孔、低密度固体材料，其中凝胶的液体组分已被气体取代。凝胶的固体网络构成了气凝胶的结构，从而产生极低的热导率。
