辐射

Combustion air/natural gas premixing, air staging and forced internal recirculation are integrated into a single burner to achieve low NO X emissions without sacrificing energy efficiency.

燃烧空气和天然气预混合、空气分段运输和受迫内循环结合构成一个燃烧器，在不牺牲能效的情况下达到低 NOx 辐射。

Experiments is located at Yucheng Comprehensive Experimental Station, Chinese Academy of Sciences, Yuchen County, Shandong Province (Latitude: 36°57′N, Longitude: 116°36′E, and Altitude: 20m) in 2000～2001 and 2001～2002 winter wheat growing seasons. Mainly observed factors under sprinkler irrigation and surface irrigation conditions include (1) dry and wet bulb temperature and wind speed at four heights, radiation, soil temperature and water surface evaporation of 20cm standard pan on the top of canopy;(2) winter wheat tillering, stem height, leaf area, biomass and yield; and (3) soil water content and winter wheat evapotranspiration.

实验在中国科学院禹城综合试验站进行，主要观测内容包括：（1）喷灌和地面灌溉条件下近地面不同高度处的温度和湿度、辐射、地温和冠层顶部水面蒸发量等农田小气候要素；（2）叶面积、生物量和产量等作物生长要素；（3）土壤水分变化过程、农田蒸发过程和冬小麦耗水量等要素。

The United Kingdom has pledged to provide technical assistance to the peacekeeping effort in Darfur, including airlifting supplies and equipment to assist the African peacekeepers.

英国承诺为达佛的維和努力提供技术帮助，包括提供非洲的維和部队空运补給和裝备。

Results: The level of ET-1mRNA in placental villus was significantly higher in pre-eclamptic women than that in control group.
