Effect of sole Y2O3 additive on the nitridation behavior of silicon powder was systematically studied using thermo gravimetry, differential thermal analysis, particle size analysis, X‐ray diffraction analysis, X‐ray photoelectron spectroscopy, scanning electron microscope and thermodynamic analysis in this paper. The thermo gravimetry results showed that Y2O3 additive can significantly decrease the...
Use of fuzzy mathematics in evaluation of thermal and moisture comfort of ramie fabrics and bamboo-cotton fabrics is introduced. The thermal transmittance, air permeability, moisture vapor transmission, and hygroscopicity of fabrics with different specifications are tested, and their thermal and moisture transmitting properties are compared with that of silk fabrics through fuzzy similar priority...
