The linear range of the electric pole is 10~(-5)—10~(-1)mol dm~(-3), the lower measuring limit may reach 5×10~(-6)mol dm~(-3). The actual tangent of the pole is 28mV, its pH range is 5.3-12.0, and the performance for measuring Ca~(2+)in water is good.
Under this condition,exchange current density is biggest 0.1441 mA/cm~2.The experimental result of single factor shows that:The electric pole cathode polarization is minimum when La-(0.8)Sr-(0.2)CoO-3 content is 9.09% and Na-2SO-4 content is 45.45%.
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.
