Abstract
A high-efficiency and high signal-to-noise ratio surface nuclear magnetic resonance detection method is provided. The present disclosure adopts a concentric arrangement of a direct current transmitting coil and an alternating current transmitting coil to form a transmitting coil group, replacing the traditional single alternating current transmitting coil. Through the change of magnetization intensity caused by alternating excitation, the direct current emission time, alternating current emission time and emission interval time are adjusted, and the magnetization intensity is controlled to be gradually accumulated and stabilized in a certain range, thus improving the macro magnetization vector of hydrogen atoms. The single pulse emission time of the alternating excitation emission mode provided by the present disclosure is within 1 second, which can effectively improve the detection efficiency. The present disclosure achieves the effect of simultaneously improving the signal-to-noise ratio of surface nuclear magnetic resonance detection signals and enhancing detection efficiency.
