. The functional form of mathematical model for temperature field of induction melting process is given. The calculus of variations of the temperature in dispersing triangle unit was done. The stiffness......
of Science and Technology, Harbin 150080, China) Abstract: Effects of alternating electromagnetic field on the grain size, concentrating shrinkage cavity, dispersing shrinkage porosity and density... with the increase in alternating electromagnetic field intensity. The depth of concentrating shrinkage cavity is decreased about ten times when magnetic intensity is 0.2T. The volumes of both dispersing......
as collector and methyl isobutyl carbinol (MIBC) as foaming agent. The effect of the amount of collector and foaming agent, the type and the mount of inhibitor agent and dispersing agent were investigated... sphate, sodium polyacrylate and MIBC are 0.15,0.75,0.75 and 0.84 mg, respectively, the recovery rate of lithium cobaltate is 93% using sodium hexametapho sphate as dispersing agent and sodium......
there was only pure co-precipitation reaction and the speed of co-precipitation reaction was too high to have enough time of PEG. dispersing particles.关键词:......

at which hydrocarbon(HC) conversion reaches 50%) of only 237 ℃. However, Pt particles prefer dispersing on the external surface of KIT-6-40 due to those too small pores.关键词:......
Dy3+ activated LaVO4 films synthesized by precursors with different solution concentrations吴丹丹,马永青,张贤,钱仕兵,郑赣鸿,吴明在,李广,孙兆奇School of Physics and Materials Science, Anhui University摘 要:Using different-solution-concentration precursors with citric acid as chelating agent and polyvinyl alcohol as dispersing media, Dy3+ activated LaVO4 films were deposited......
nanoparticles were prepared by a modified co-precipitation method with graphene oxide(GO) nanosheets used as dispersing agent. The GO concentration is controlled at 0.0.005,0.01, 0.02, and 0.03 g/L......
. It is verified that the citrate ligand significantly affects the morphology of zinc oxalate particles, probably via its multiple roles of chelating, dispersing, and selective absorption. Thermodynamic......
to that of the composite antistatic agent fabricated by direct dispersing CNTs in the antistatic agent carrier. Moreover, the heat-treated CNTs could further enhance the antistatic effect compared with the initial......
