【Abstract】 By use of adjusting and stabilizing speed integrated circuit, with adjusting voltage,self feedback (electron) stabilizing speed is achieved’ The influence of solution damping change on the rotation speed of generator in the experiment is eliminated. With high precision clock signal and decimal counter,photoelectric measurement speed is accomplished.更多还原
