peak-to-peak voltage
2.Using the MOS linear composite cell, the CMOS transconductance operational amplifier is designed. The linearization principle of the design is distinct and the circuit structure is simple. SPICE simulation results show that for ±5 V voltage supply and less than 1% nonlinearity error the maximum differential input voltage range is 8 V(peak to peak), and -3 dB bandwidth is 10 MHz.
5.The lithium diffusion coefficients, corresponding to anodic peak and cathodic peak in LiFePO4, obtained from CV were 4.3×10-11 cm2·s-1 and 3.8×10-11 cm2·s-1. The lithium diffusion coefficients obtained from PITT varied with potentials, and the lowest value was about 5.5×10-11 cm2·s-1, coinciding with the voltage plateau region in the charge curves.
7.The positive voltage at the current of 20 mA was 1.2 V and the electroluminescent (EL) peak wavelength was 938 nm. And the reverse voltage at 10 μA was 5～6 V.The output power at the current of 50 mA was 3.5 mW corresponding to 1.3 V.And the maximum output power of 12 mW was obtained at the current of 300 mA.
8.A new method of capillary electrophoresis to determine residue chlordimeform in honey was developed by means of capillary electrophoresis sample stacking technique. The influencing factors of analyte peak height, such as the phosphate concentration, methanol concentration and pH of running buffer, separation voltage, methanol concentration in sample and injection time, were optimized.
9.especially at the peak on 25.0 aum,it is mostly effected by the process parameters:the intensity can be increased twice,eighty times,four times,six times and six times,respectively,when the pulsed-voltage,pulse width,frequency,sputtering pressure and RF power are varied from 10 kV to 20 kV,from 40 μs to 100 μs,from 50 Hz to 200 Hz,from 0.1 Pa to 0.3 Pa and from 200 W to 400 W.
