The results show that the bifunctional oxygen electrode has the most catalytic current when the ratio of catalyst to ethine black is 7∶3 and the pole, which is composed of nickel net and mixture of La 0.75 Sr 0.25 NiO 3 and ethine black, performs better catalytic activity than that is composed of nickel net and ethine black.
The invalidation behavior of RuTiSn,RuTiIrSnCo,IrTiTa and Pt/Ti pole in 1 mol/L H 2SO 4 was studied. The results indicate:The aggrandizement electrolysis longevity of IrTiTa anode is the longest,Pt/Ti anode is more long,RuTiSn anode is the shortest.

Otherwise, with the result of research before, this research designed the air cleaner integrally, including the configuration of electric pole, the shell of air cleaner, the measure of high voltage insulation in the cleaner and so on.
In this paper, a new construction type of membrane electrod─binetwork membrane electrode is suggested, whose catalyst layer is interconnectively composed of catalyst network of Pt/C coated with thin Nafion film having high gas diffusibility and the electrolyte network of carbon coated with thick Nafion film having high proton conductivity.
In practice, the measuring electrode is so small that we can simplify the corresponding equalued surface to a point.
Study and Application of Electrochemical Behavior of Calcium-ARS on a Mercury Film Electrode
A sensitive complex absorptive wave of Ca-ARS was obtained by using differential pulse voltammetry when a mercury film glass carbon electrode was immersed in 0.1 mol L-1 KOH and 4.5×10-4 mol L-1 ARS solution.
The electrochemical behavior of the system was also studied by cyclic voltammetry, and the experiment results showed that the electrode process was an irreversible absorptive with two electrons participating.
On the condition of weak acidity, the sensitive layer was prepared by electropolymerization of o-aminophenol on a gold electrode in the presence of the template (nicotine).
Firstly, the construction of HEPMSG is improved with the addition of PM excitation on the ferromagnetic pole, and its working principle and design method are studied in detail.
Optimal approximation of head-related transfer function's pole-zero model based on genetic algorithm
Based on the analysis of the HRTFs' spectrum and some perspectives of psychoacoustics, this paper applied multiple demes' parallel and real-valued coding genetic algorithm (GA) to approximate the HRTFs' zero-pole model.
Considering the salient pole and high magnetic nonlinearity of the electromagnetic doubly salient (EMDS) DC generator, a 12/8 pole prototype EMDS generator is designed and calculated using a 2-D finite element method (FEM).
There are four pole-pair coils in the stator supplying actuation currents.
