查询词典 gas-forming reaction

A novel Belousov-Zhabotinskii type oscillating reaction was observed in a closed serine-BrO^-~3-Mn^2^+- H2SO4 system(Ser-BZ system), which exhibited the followign characteristics:(1)Although Ser is unable to be brominated, the sustained oscillations could still be observed in the above system under batchreactor conditions even in the absence of either acetone or inert gas flow.(2)The present oscillations displayed extremely short induction period(0) and very few oscillation number(1).(3)Cl^-, acrylonitrile, or Br^- could effectively inhibit the oscillations. However, in the case when enough Ag^+ was addedinto the system to completely inhibit the oscillations in , the oscillations on the Pt-electrode could still be observed.

首次报道了间歇釜中以丝氨酸-BrO^-~3-Mn^2^+-H2SO4为体系的新型BZ类振荡反应，其特征如下：(1)虽然Ser不能发生溴代反应，但即使在无丙酮或惰性气体流时也能在间歇釜中观察到持续振荡；(2)振荡诱导期极短(～0)，振荡次数较少(1次)；(3)振荡反应受到Cl^-，Br^-，丙烯腈等的抑制；但当加入足够量Ag^+使的振荡抑制后，仍可在Pt电极上观察到振荡现象。

The scientist has thought of two solutions: One kind is the gas floats the law, even if the train massive jet uses its reaction to the railway rail ground to do the best you can the train to float off; Another kind is magnetism floats the law, namely uses between two magnetic poles of the same name between the magnetic repulsions or two different famous magnetic poles the magnetic attraction causes the train to surface the boat from the railway rail.

The results showed that functional nanometer ITO powders of 30-50nm size with dispersion performance can be prepared. The condition is that indium salt concentration is 88mmol/L, SnO2/In2O3 =5.3wt%, reaction solution PH value is 8, The precursor are thermally reduced at 450 ℃ under hydrogen gas ,at the sametime adding 6at.% KC1 salt to indium tin salts.
