Prof. Zhang Zhonghua

Curriculum Vitae

Dr. Zhang Zhonghua got admission to Department of Engineering physics, Tsinghua University in 1957 and then transferred to Department of Electrical Engineering and Atumation in 1959. After his undergraduate studies in 1962, he went further postgraduate study. To reward to his contribution to accurate measurement on electricity, Dr. Zhang was honored as National Advanced Worker in 1990, and government special allowance in 1991. He was awarded the scientific and technological award by China Instrument and Control Society for his contribution in basic quantity of electricity measurement in 2001. He received the HeLiang hori fund of scientific and technological award in 2003. Dr. Zhang Zhonghua published over 60 pieces of academic paper on domestic and international scientific journals and participated in editing work of 6 scholarly treatises. He now hosts concurrent post as chief editors for Chinese Journal of Scientific Instrument, Acta Metrologica Sinica, Electrical Measurement & Instrumentation and has done a lot of work for academic exchange. He also took part in the work of societies and acted as vice-director-general of China Instrument and Control Society, director-general of China Society of Measurement. From April, 2011, he took the position as special consultant for Jiangsu Province Insitute of Quality and Safety Engineering.

Accomplishments

He was in charge of establishing national electricity capacity by method of transpose capacitor, which was traceable to the uncertainty of 1×10E-7. In 2007, he participated the international comparisons of 10pF organized by BIPM, which achieved the uncertainty of 4×10-8. From 1983 to 1988, he established the standard of high-intensity magnetic field by using nuclear magnetic resonance method(2-12 Tesla, uncertainty 6×10E-5) . He developed the inhibition method to overcome the long-distance transmitting problem of crogenic nuclear magnetic resonance method, which was among one of the best standard around the world. In 1992, he was awarded the second prize of the State Scientific and Technological Progress Award for this project. From 1987- 2002, he was responsible for the programme of Quantum Hall Resistance to establish the electricity resistance. Recently, he elected as the member of CODATA.
