With the establishmentof the equivalent medium model, RTM-DRE was applied to study radiative transfer intransparent medium with scattering particles. By taking into account of absorption andscatter of particles, absorption of binder and reflection of interface, the apparent spectrumabsorption model of thermal control coatings was developed by RTM-DRE combined withMies theory. Validity, computational error and time of the model were validated andanalyzed. Furthermore, the apparent spectrum absorption characteristics of thermal controlcoatings were studied, and the influences of optical characteristics of binder and particles,volume fraction of particles, particles diameter, characteristics of interface, and incidentangle of irradiance were analyzed.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
