将空位声子散射理论应用于氧化锆和金红石中的氧空位。这些空位是稳定化氧化锆点缺陷散射的主要来源。结果表明，该理论与还原金红石的热扩散率降低有很好的一致性。这增加了氧空位对稳定氧化锆导热系数的影响的信心，特别是在热障涂层中。(C)1999 Elsevier Science B.V.保留所有权利。
The theory of phonon scattering by vacancies is applied to oxygen vacancies in zirconia and rutile. These vacancies are the major source of point defect scattering in stabilized zirconia. It is shown that the theory agrees well with thermal diffusivity reductions in reduced rutile. This lends confidence to the effect of oxygen vacancies on the thermal conductivity of stabilized zirconia, particularly in thermal barrier coatings. (C) 1999 Elsevier Science B.V.
