Title : Remote Sensing Integrated Identification of Geological Hazards in the Batang—Mangkang Section of the Sichuan—Tibet Highway
LIU Xinghong, , YAO Xin, , YU Kaibing, , DAI Fuchu, , WANG Shifeng, , YAO Jiaming,
Abstract : The Batang—Mangkang section of the G4218 highway is located in the transition zone from the Jinsha River Valley to the plateau, and facing with strong neotectonic activities, broken rock masses and frequent geological disasters. Therefore, the construction and maintenance of the highway in this region are of huge difficulties. Traditional ground geological survey methods face many difficulties in highway route selection, disaster assessment and stability analysis, etc. Combining the optica

Title : Research Conception and Achievement Prospect of Key Technologies for Forecast and Early Warning of Flash Flood and Sediment Disasters in Mountainous Rainstorm
LIU Chao, , NIE Ruihua, , LIU Xingnian, , XU Weilin,
Abstract : The mountain flood disaster is one of the major natural disasters in the world. The global economic loss caused by flash floods in the 21st century has reached more than 46 billion US dollars per year. The area of mountain flood disaster prevention and control accounts for about 40% of the land in China, whereas the fatality caused by mountain flash floods account for approximately 70% of the death toll from flood disasters. In recent years, the construction of mountain torrent disaster preventi

Title : Thermal Damage of Monocrystalline Silicon by Multi-pulsed Millisecond Laser
GUO Ming, , ZHANG Yongxiang, , LI Hong,
Abstract : Monocrystalline silicon is widely used in the field of photoelectric systems, and it is easy to cause its thermal damage and change of performance under the action of laser. For the urgent needs of high-precision laser weapons and laser fine processing industry, the thermal damage of monocrystalline silicon irradiated by pulse train of millisecond laser andthe relationship among the laser energy density, number of pulses and other important parameters of thermal damage were analyzed, and the dam
