2004年河北省的降水特性

结合防汛水情工作的实际，从水文水资源角度系统、客观又有所侧重地分析了2004年河北省降水的时空分布特性、关键性降水出现时机及落区对我省水库蓄水的影响、大中型水库洼淀汛末蓄水状况，不仅探讨了风调雨顺之年的基本特征，而且有助于探索洪水资源化的实现途径。还为及时了解掌握2004年水资源动态变化的新情况，以便合理安排今冬明春生产、生活及生态用水提供了科学依据。     

湟水流域水源地基本特征与保护对策

通过分析湟水流域水源地的地貌、气候、水文、社会经济特征,指出水源地存在水土流失、森林减少、草地退化、人类活动增加、水质污染等生态环境问题。提出保护流域水源地的对策:尽快制定水源地水资源保护规划,实施生态保护工程,依法治水、管水,严格取水许可制度,实现可持续发展。     

Concentrating solar power for seawater desalination in the Middle East and North Africa

The paper presents a long-term scenario for the demand of freshwater in the Middle East and North Africa (MENA) and shows how it may be covered by a better use of the existing renewable water sources and by sea water desalination powered with solar energy. Growth of population and economy, increasing urbanization and industrialization, and the rather limited natural resources of potable water in MENA are leading to serious deficits of freshwater in many parts of MENA. Modern infrastructure for water distribution, enhanced efficiency of use and better water management are to be established as soon as possible. However, even the change to best practice would leave considerable deficits, which are poorly covered by over-exploiting groundwater resources. Increased use of desalted seawater is therefore unavoidable in order to maintain a reasonable level of water supply. The desalination of seawater based on fossil fuels is neither sustainable nor economically feasible in a long-term perspective, as fuels are increasingly becoming expensive and scarce. Concentrating solar power (CSP) offers a sustainable alternative to fossil fuels for large scale seawater desalination. CSP can help to solve the problem, but market introduction must start immediately in order to achieve the necessary freshwater production rates in time.

平面上任意形状范围内的磁荷分布

依据磁的库仑定律计算出几种最简单系统(一维5磁荷系统、一维7磁荷系统、一维正方形13磁荷系统和二维矩形17磁荷系统)的磁荷分布,进而得出解决平面上任意形状范围内磁荷分布问题的一般方法和具体步骤,从而证明平面上任意形状范围内的磁荷分布问题理论上可由磁偶极子法来解决。
