The single-scattering properties of ice crystals are fundamental to the radiative transfer in ice clouds, which thereby are the basis for estimating the optical and microphysical properties of ice clouds. In this paper, with the particle internal reflection, refraction and multiple diffraction correct Van De Hulst anomalous diffraction (ADT), which thereby get more precise calculation for non-spherical...
The asphalt was modified with waste PVC and SBS, adopt 2%SBS+PVC and 4%SBS+PVC (the percentage of total asphalt system) two processes to compound modification of 90# asphalt. The softening point test, penetration at 25 °C test, ductility at 5 °C test and PI index were performed to characterize the modification effects. The results show that, the waste PVC/SBS compound asphalt can effectively increase...
