气凝胶中的超流体3He提供了一个独特的机会来研究短的平均自由程对具有各向异性配对的定义良好的超流体费米液体的性质的影响。传输系数和集体激励，例如纵向声音，预计反应敏感的短平均自由程，并提供测试最近开发的模型在气凝胶股准粒子散射的可能性。健全的实验，再加上费米液体理论的基础上的理论分析，系统与短的平均自由程，应该提供有价值的见解超流3He和气凝胶之间的相互作用。
Superfluid3He confined in aerogel offers a unique chance to study the effects of a short mean free path on the properties of a well defined superfluid Fermi liquid with anisotropic pairing. Transport coefficients and collective excitations, e.g. longitudinal sound, are expected to react sensitively to a short mean free path and to offer the possibility for testing recently developed models for quasiparticle scattering at aerogel strands. Sound experiments, together with a theoretical analysis based on Fermi liquid theory for systems with short mean free paths, should give valuable insights into the interaction between superfluid3He and aerogel.
