Erosion and Sediment Production in Small Watershed in Purple Hilly Areas and Prevention Techniques

Purple Soil distributes extensively and mainly in China. Because of abundant easily weatherable parent rocks/materials and unstable soil structure, and also influenced by parent materials, usage systems, and slope gradients, erosion and sediment production of purple soils are very severe with main fashions of water erosion and gravitational erosion. Basing on observed data in small watersheds, rainfall erosivity,vegetation coverage, previous soil water content, flow and relating factors such as climate, topograph of small watershed,land usage, and soil kinds are all the influence factors of erosion and erodibility of purple soil as well as sediment production and transport in small watershed of purple hilly areas.The effective technological countermeasures of ecosystem restoration, agricultural tillage for water conservation and erosion prevention, agriculture project, and soil changing for fertility and anti-erosion were provided.

服务地方经济与社会体现区位优势和特色--高职院校学报发展概览

近年来高职院校学报迅速发展，取得了良好的社会效益，但还存在着诸如竞争力不强、未能体现高职院校特色等问题。因此，高职院校学报应当在谋求自身发展的同时，积极探索高等职业教育与区域经济发展的互动模式，为实现地方经济全面、协调和可持续发展提供参考依据，对区域经济发展起到推动作用，并在此过程中体现自身的特色。     

沉积盆地侵入岩区的异常“温度场、压力场和地球化学场”与油气的关系——以东营凹陷纯西辉长岩为例

通过岩石学、有机地球化学等分析 ,发现纯西辉长岩周围烃源岩具有有机质含量极低、高熟和裂缝发育以及油气比较丰富等特征 .研究表明 ,其根源是辉长岩形成的特殊温度场、压力场和地球化学场 ;辉长岩形成的异常高温大大促进了烃源岩热演化 ,并提高了生烃量 ;高压产生的大量裂缝为烃源岩排烃和油气聚集提供了通道和储集空间 ;而辉长岩带来的深源氢对烃源岩起到加氢作用 ,扩大了生烃量

Dynamic Characteristics of Inter-Satellite Links in LEO Networks

To establish an efficient inter-satellite link (ISL) in an LEO network, the effect of geometric characteristics of ISL on the ISLs and the devices on the LEO satellite should be examined. Because of the continuous movement of the LEO satellite, the time-varying behaviours of the ISL's geometric charactersistics continuously change with the changes of the satellite's position on the orbit. These dynamic geometric characteristics of the ISLs are important for ISL's performance analyzing and the design of the devices on the LEO satellite. This paper describes dynamic geometric characteristics of ISL, analyzes the impact of these regulations on the tracking system of the satellite's antenna and the power adjusting system of the satellite's transmitter, with the Iridium system as an example.
