Theoretical analysis, numerical simulation and field rainfall experiment and indoor artificial rainfall test methods have been applied to study the fundamental mechanism and process of rainfall infiltration induced landslides currently.Field test consume large manpower, material and financial resources, test period is too long, while the indoor artificial rainfall test combines the advantages of unit test and field test,which become a powerful tool for further study of the response rule of the unsaturated soil slope under rainfall conditions.

Analysis of energy efficiency of cooperative communication in Wireless Sensor Networks Liming Jin JiangXi YuZhou Vocational College of Science & Technology, Xinyu, Jiangxi, 338000 Keywords: wireless sensor networks; communication technology; efficiency analysis Abstract: Wireless sensor network (WSNs) is composed of a large number of cheap micro sensor nodes with wireless communication and computing capabilities, which will deploy in unattended monitoring area through the cooperation of autonomous monitoring tasks assigned, and sending the information of monitoring object collection to intelligent monitoring network system for remote users.
Marching, armed distribution and military material will supply situation, therefore the need to build a wireless sensor network to collect these information, And by the sink node transmitting the collected data to the command, the final fusion from the battlefield data form a perfect theater situation map.
