Main research results include: through theoretical research and experiments, a high-pressure, Fourier transform ion trap mass spectrometer was realized, which increased the working pressure of the ion trap ~50 times, making it a new, high-performance ion trap mass spectrometer. The working principle of the instrument provides a theoretical and experimental basis; in response to the needs of quantum computing and high-throughput biochemical analysis, a new ion trap structure was proposed, and the world's first large-scale, low-cost 3-dimensional ion trap array was successfully realized. Currently, he has been authorized an international invention patent and a provisional international invention patent (Provisional patent); he has published 19 papers in international journals (SCI, EI). He has been invited to give 9 conference reports and 16 other conference papers, and received travel funding for two international conferences (URSI 2008, ASMS Asilomar 2008).
