A stepwise carbochlorination-chemical vapor transport(SC-CVT) technique is proposed for separation of thorium from mixed bastnaesite-monazite concentrate.
Sevoflurane is synthesized from aceton by vapor phase catalytic fluorination, vapor phase catalytic hydrogenation,chloridization and fluoromethylation, which gives a new synthetic method.
Objective: To probe the effects of siritch vapor condensate(SVC) on lipid peroxidation and of SOD-Se-enriched fruits of Lycium Barbarum L on anti-peroxidation in mice.
In this paper, the mathematical model of the reltion between water saturation vapor pressure and saturated temperature is established in the form of monoacidic polynomials.
Thewater vapor oxidation is take the high pure water steam as theoxidizing atmosphere, responds the production silicon dioxide by thesilicon chip surface silicon atom and the hydrone.
It Is necessary to include as a heat source In the thermodynamic energy equation at erm which represems the timerate of release of the latent heat of condensation of water vapor.
When the vapor emanated from the skin surface can not easily permeate to the air, it will form a high humidity region between the skin and the fabric which makes people feel mugginess and discomfort.
