农林飞机结构抗坠毁设计技术

农林飞机通常在3-5m的超低空进行作业飞行,在离地面3m以上的空中往往会有树木、电线杆、电线、堤坝、土堆、山丘、建筑物等障碍物,稍有不慎,就有与之撞击的可能。这样的工作条件除要求飞机具有良好的超低空飞行性能以外,还要求飞机具有一定的耐坠撞能力。本文针对农林飞机执行任务过程中可能发生的碰撞、坠毁等特点,研究了农林飞机抗坠毁设计技术、计算分析仿真技术。     

战争中毁灭的人生——邓一光小说《远离稼穑》人物分析

在战争中个人要承受生命中怎样无法言说的沉重,作家邓一光通过他的中篇小说《远离稼穑》进行有益的探索,刻画"我的四爷"这样一个有过三次特殊被俘经历的人物形象,表现作家以勇气和胆识对战争文学题材的开掘与对角度的拓展所做出的努力。     

发展农业现代化若干问题的思考

没有农业的现代化就没有中国农业生产现代化，通过分析我国农业现代化的基本现状和存在的问题，提出了只有提高农业劳动生产率，开拓现代农业新领域，调整产业结构，发挥比较优势，坚持科教兴农，走集约化农业发展道路，我国农业的现代化和社会主义新农村建设才能取得更大的成效。

对陕西农业信息市场建设的思考

农业信息市场的建立和完善对促进陕西农业经济发展具有重要的作用,也是增加农民收入、减少坑农害农的重要手段。转变思想、树立信息战略资源观念;加大政府投入;强化农业信息人员配置;创新信息传播载体和激励机制是建立陕西农业信息市场的有效措施。     

Earth observation and UK science policy

This paper examines the way in which Earth observation is linked to UK science policy through the 1993 UK science White Paper and subsequent policy statements, and how the central theme of partnership has been developed in practice. An example of crop yield prediction is given to illustrate the strengths and the weaknesses of the approach. The UK science and space strategies are set in the context of the European Strategy for Space and links are made to the US global change research strategy.     

韩城区域经济发展的定位与思考

韩城，是我国著名的历史学家司马迁的故乡，是我国历史文化名城。但她仅是一座县级城市，一座小城，其经济状况与历史名城极不适应。韩城要发展，重点是要定好位，并给予政策扶持。要以文化产业为先导，振兴旅游业，带动现有的强势工业的改造和升级，发展特色农业，使韩城真正成为一座文化大市，旅游强市，煤炭、电力、钢铁发达，特色农业鲜明的现代化区域中心城市。

Spatio-temporal dynamics in the phenology of croplands across the Indo-Gangetic Plains

Spatio-temporal dynamics in land surface phenology parameters observed over croplands can inform on crop-climate interactions and, elucidate local to regional scale vulnerabilities either due to climate change or prevailing sub-optimal agricultural practices. Here, we observe spatio-temporal trends in land surface phenology parameters (cropping intensity, length of growing season and productivity) for kharif and rabi cropping seasons from satellite data across the Indo-Gangetic Plains from 1982 to 2006. The productivity of the Indo-Gangetic Plains croplands is of regional importance and is a vital component of Indian national food security efforts. Aside from local and intra-state heterogeneity in observed trends there was a clear west-to-east gradient in cropping intensity. Key observed trends include increasing cropping intensity in the eastern IGP, increasing number of growing days per year in Bihar, Uttar Pradesh and Haryana and increasing productivity in both cropping seasons across the IGP. This information is a crucial input to integrated assessments of the croplands to ensure management of the agricultural system shifts towards a trajectory of climate-resilience and environmental sustainability.     

Initial design of laboratories for sustainable habitation

An effective and self-sustainable artificial habitat design is essential for human spaceflight and expansion of mankind into orbit or towards other celestial bodies. There are two approaches that need to be implemented in future sustainable habitats: the use of re-cycling technologies in order to gain experience in closed-loop processes and the primary production of resource materials using In Situ Resource Utilisation (ISRU) principles. Various products will be provided and, where applicable, recycled in such a system taking into account basic human factors requirements such as crew work load capacity, safety and well-being, namely:
