Blood pulse flow, pulsatility index and standard deviation of blood flow were elevated from 317±48ml/min, 2.85±0.21 and 96±21 ml/min to 447±88 ml/min, 4.56±0.90 and 131±39 ml/min before and during EECP (P<0.05).
The result of the test indicated that the pressure pulse conditions should be from low pressure 0. 05 mPa 10 mm to high pressure 0. 2 mPa 30 min, the best fermentation conditions should be water content 58%, pH 8. 5 and temperature culture 28℃.
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 reaction mechanism between isoquinoline and ·OH radical in aqueous dilute solutions under different conditions was studied by pulse radiolysis.
The electrochemical behavior of ciprofloxacin (CFX) and its interaction with the natural calf thymus DNA (ctDNA) is studied by using pulse difference voltammetry on a carbon electrode.
Furthermore, it is clear that when carrier signal h(t)=0, closed-loop pulse-width modulation (PWM) DC-DC converters are not well posed, and when some condition is satisfied, the closed-loop PWM DC-DC converters with a P controller are well posed.
In this paper, the authors propose a new space vector pulse width modulation (SVPWM) algorithm based on non-orthogonal coordinates for N-level inverters.
