Abstract:Professor HE Ji-shan is a famous geophysicist, educator, engineering management expert and one of the masters who epitomize the electromagnetic methods in China. He was born in Liuyang County, Hunan Province in 1934, graduated from the Department of Geophysics, Changchun College of Geology in 1960. He was elected to be an academician of the Chinese Academy of Engineering in 1994. He once served as the president of Central South University of Technology, the vice chairman of the Nonferrous Metals Society of China, the vice president of Chinese Geophysical Society, the director of Energy and Mineral Engineering Division of Chinese Academy of Engineering, the Chairman of Hunan Association for Science and Technology, and the chief editor of The Chinese Journal of Nonferrous Metals and Transactions of Nonferrous Metals Society of China from 1991 to 2001. Currently, he is not only the honorary chairman of Hunan Association for science and technology, but also the fifth presidium member and a member of the Standing Committee of the Division of Engineering Management of the Chinese Academy of Engineering, as well as a life member of the Society of Exploration Geophysicists. Professor HE Ji-shan has been involved in the geophysics research for a long time to make remarkable academic achievements. He created the Dual Frequency IP method and invented the Dual Frequency IP instrument. He has not just proposed the closed addition in a three-element set, but achieved the fast recursive coding of 2n Sequence Pseudo-Random Signal, and established the electrical system based on Pseudo-Random Signal as well. Moreover, he has established the Flow-Field method with high-resolution to detect the water inlet of the piping and seepage in dykes and dams, which provides the essential technical support and the scientific decision-making basis of emergency restoration for detecting the hidden dangers of dilapidated reservoirs and investigating the hazards of embankments in flood season. He has unified the definition and algorithm of the entire field resistivity of the frequency domain electromagnetic methods, and created the Wide Field Electromagnetic method to open up a brand-new research area for the electromagnetic exploration. He has also created the first national key discipline of China, which features the geo-electric field and observation system. What’s more, Professor HE has invented a series of geo-electric field observation instruments and equipments with international advanced levels and independent intellectual property rights, and made significant contribution to the resource exploration and engineering survey development of China. The exploration geophysics theory system characterized by the Pseudo-Random Signal Electromagnetic method and Dual-Frequency IP method that Professor HE has created and developed, has been hailed as a major event of applied geophysics internationally. His study has important guiding significance on the development of geophysics of China.
