Measurement of ionospheric large-scale irregularity

引用

Science China(Technological Sciences) 1996年第5期39卷 511-525页

作者：韩文焌郑怡嘉张喜镇 Beijing Astronomical Observatory Chinese Academy of Sciences Beijing 100080China

Based on the observations of a meter-wave aperture synthesis radio telescope,as the scale length of ionospheric irregularity is greatly larger than the baseline length of interferometer,the phase error induced by the output signal of interferometer due to ionosphere is proportional to the baseline length and accordingly the expressions for extracting the information about ionosphere are *** using the ray theory and considering that the antenna is always tracking to the radio source in astronomical observation,the wave motion expression of traveling ionospheric disturbance observed in the total electron content is also derived,which is consistent with that obtained from the conception of thin-phase screen;then the Doppler velocity due to antenna tracking is *** the inversion analysis for the horizontal phase velocity of TID from observed data is given.

On Fundamentals Predicting Floods-Landslides

引用

Journal of Earth Science 1998年第3期17卷 64-67页

作者： Yan Tongzhen Li Yun ’an Wang Hongxing Faculty of Engineering, China University of Geosciences, Wuhan 430074 Yi Shunmin State Key Hydraulics Laboratory of High Speed Flows, Sichuan Union University, Chengdu 610065

Based on the floods landslides commensurability system, the paper presents and discusses the disasters/hazards with comprehensive interaction and erosional processes. However, people are not enough to get their possibility for the sustainability. They have had so many disasters to meet and to control continuously. Finally, the fundamentals should be built up with nonlinear solutions of landsliding problems; the events of geomagnetism anomaly should be considered.
