total voltage
1.The gate length L, the free-carrier concentration N in the active layer and the thickness a of this layer can be calculated to predict the minimum noise figure NFmin of the device on condition that the total gate-source capacitance Cgs, the intrinsic transconductance gm and the total pinch-off voltage Wp of the device are precisely measured.
4.Results Electransfection efficiency was increased to the highest value,up to about 49.7% when imDCs with the concentration of 5×10~6 cells/ml were mixed with 40μg-total RNA of human hepatocarcinoma cell,the electric voltage of electroporation apparatus was set at 300V,and the time of impulse was 500Us.
9.This problem may be solved by addition of a small amount of argon (ranging from 0.02 to 0.40 of the total pressure of the gas mixture). Various parameters of the color AC PDP filled with Ne Xe Ar gas mixture,including the firing voltage,operating margin of sustaining voltage,luminance,luminous efficiency and white field chromaticity,were studied to understand the influence of the argon addition on the performance of the AC PDP.
