The optical cross sections of the Al 2O 3 C composite microparticle groups were calculated by using Aden?s and Kerker?s theory of Mie scattering. The emissivity spectra of the mixed groups of Al 2O 3 C composite microparticles were also calculated.是什么意思_The optical cross sections of the Al 2O 3 C composite microparticle groups were calculated by using Aden?s and Kerker?s theory of Mie scattering.
