;热力学;粒径 中图分类号:TQ131.2 文献标志码:A Effect of particle size on precipitation-dissolution equilibrium of CaF2 JIANG Ke, ZHOU Kang-gen, LI Cheng... and particle size of CaF2 on the precipitation dissolution equilibrium of Ca2+-F--H+-H2O system were investigated, and then the factors influencing the precipitation effect were determined combined......
Influence of particle size and temperature on the dielectric properties of CoFe2O4 nanoparticlesRajnish Kurchania22. Department of Physics,Maulana Azad National Institute of Technology (MANIT)摘 要... nanoparticles were synthesized using a chemical coprecipitation method. The particle sizes were calculated according to the Scherrer formula using X-ray diffraction(XRD) peaks, and the particle size......
Influence of Carboxyl Groups on the Particle Size and Rheological Properties of Polyacrylate Latices张心亚School of Chemistry and Chemical Engineering,South China University of Technology摘 要:particle size when the alkalinization temperature is 50......
J. Cent. South Univ. Technol. (2008) 15: 309-312 DOI: 10.1007/s11771-008-0058-z Spray deposition for making large size billet with swing atomizer LI Jian-ping(李建平), LIU Tao(刘 涛), TANG Qing-yun... spray deposition process, which has direct influence on the size and surface texture of the billets. To resolve the problem of manufacturing large size billets, a method of spray deposition......
where they adsorb onto quartz surface, resulting in an expected increase in butyl xanthate collector adsorption with a concomitant increase in the flotation recoveries. Key words: particle size; quartz.... Aimed at revealing mechanism of metallic ions activation on different particle size of quartz (37-74 μm and <37 μm), six common ions (Pb2+, Cu2+, Fe3+, Fe2+, Mg2+, Ca2+) are introduced as activators......
impoverishment problem of SMC-PHD filter As previously mentioned, to avoid particle degeneracy and prevent exponential growth of the particle size, the resampling step is recommended in standard SMC-PHD...J. Cent. South Univ. (2017) 24: 1826-1836 DOI: https://doi.org/10.1007/s11771-017-3591-9 A novel SMC-PHD filter based on particle compensation XU Cong-an(徐从安)1, HE You(何友)1, YANG Fu-cheng(杨富程)1, 2......
