In the polarization theory of porous electrode, the concept of "characteristic transmission current" and the "heterogeneous liquid film" model of gas diffusion porous electrode are put forward. The mathematical model of photoelectric conversion of semiconductor electrode and the photoelectric conversion theory of "mobile dopant" polymer semiconductor are put forward. A new differential solution to the absolute equivalent circuit of electrode AC impedance is proposed. The theoretical solution of the transient process of autocatalytic electrode is obtained.

The first electrochemical research methods and techniques are: phase-selective glow modulation method and phase-selective detection method for measuring instantaneous AC impedance; Controlled potential pulse current technology for measuring ultra-low corrosion rate: scanning microelectrode technology for measuring local corrosion. Under his guidance, the instruments successfully developed and put into production include: DHZ- 1 electrochemical comprehensive tester, XYZ- 1 ion chromatography suppressor, WF-III micro-area corrosion potential distribution measurement system, etc. , and won six invention patents. Recently, in the field of nanotechnology, a new ultra-micro complex three-dimensional graphics replication technology is proposed.
