液体火箭发动机是宇航推进家族的重要成员,将会成为下一个历史时期使有效载荷达到第一宇宙速度的唯一推进手段,是制约航天发展速度的最关键因素。发展运载系统,动力必须先行。中国在21世纪初必须推出能与世界先进国家相当的大型运载火箭。这些火箭不能建立在用原有的发动机增加数量以加大推力的基础上,必须研制单台推力更大、更先进、无污染的新型发动机,同时还需开展火箭航天飞机及其发动机使用的气动塞式喷管的预先研究,以火箭航天飞机为突破口,赶上世界先进水平。
Strategies to manage the risk of heavy metal(loid) contamination in agricultural soils

Soil contamination with heavy metal(loid)s threatens soil ecological functions, water quality and food safety; the latter is the focus of this review. Cadmium (Cd) and arsenic (As) are the toxic elements of most concern for food safety because they are relatively easily taken up by food crops. Rice is a major contributor of both Cd and As intakes to the Chinese population. Contamination and soil acidification are the main causes of high Cd levels in rice grains produced in some areas of southern China. The risk of Cd and As accumulation in food crops can be mitigated through agronomic practices and crop breeding. Liming is effective and economical at reducing Cd uptake by rice in acid soils. Paddy water management can produce opposite effects on Cd and As accumulation. Many genes controlling Cd and As uptake and translocation have been characterized, paving the way to breeding low accumulating crop cultivars through marker-assisted molecular breeding or genetic engineering. It is important to protect agricultural soils from future contamination. Long-term monitoring of anthropogenic additions and accumulation of heavy metal(loid)s in agricultural soils should be undertaken. Mass-balance models should be constructed to evaluate future trends of metal(loid)s in agricultural soils at a regional scale.
