atmospheric gases

Examples

  1. Since applied in atmosphere monitoring at the end of 1970 ` s , differential optical absorption spectroscopy ( doas ) have made quiet great progress
    差分吸收光谱技术( doas , differentialopticalabsorptionspectroscopy )自20世纪70年代末被人们应用于大气气体监测以来,在这方面已经取得了长足的发展。
  2. With annual sales of $ 7 . 7 billion , praxair , inc . ( nyse : px ) is the largest industrial gases company in north and south america , fortune 500 company , and one of the largest suppliers worldwide that supplies atmospheric , process and specialty gases , high - performance coatings , and related services and technologies
    年销售额达77亿美元的财富五百强企业普莱克斯(纽约证交所交易代码: px )是一家全球领先的工业气体专业公司,同时也是北美和南美洲最大的工业气体供应商,提供大气气体、工艺气体、特种气体、高性能表面涂料和相关的服务与技术。
  3. Main conclusions drawn from the analyses of calculating results are as follows : ( 1 ) the microwave absorption of atmosphere gas have obvious attenuation at the wavelengths for cloud detection , thereinto , the water attenuation effect changes greatly , so the 94ghz cloud detecting radar should have water vapor attenuation correction scheme . ( 2 ) when 37ghz and 94ghz radars detect clouds , the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change . ( 3 ) for the thin cloud layer and low water content of cloud , 37 - ghz radar backscatter signals are not as good as 94 - ghz radar , that is to say that the 94ghz radar has better capability in thin clouds detection
    本工作得出如下结论: ( 1 )大气气体的微波吸收在测云波段产生明显的衰减,其中水汽衰减效应变化很大;即将上天的空间94ghz测云雷达必须有水汽衰减订正方案; ( 2 ) 37ghz和94ghz雷达测云,由于大气和云衰减不同和雷达反射率的很大差异,导致雷达回波信号强弱不同; ( 3 )对云层较薄、含水量较少的云,在不计雷达参数的情况下, 37ghz雷达回波信号不如94ghz测云雷达,也就是说94ghz对薄云有更强的探测能力;对云层较厚、含水量大的云,由于强衰减的作用, 94ghz雷达回波信号小于37ghz雷达; ( 4 )从大气衰减的不利因素方面考虑,空间94ghz雷达测高层薄云的效果最好;测低层薄云时需要考虑气体衰减订正;因浓厚云的强衰减作用,探测其中下部的能力大大减弱,不仅要进行衰减订正,而且要借助其他信息来反演整个云层的含水量垂直分布; ( 5 )为了获得从极薄到极浓厚云的垂直分布探测能力,未来测云雷达系统最好采用双波长甚至三波长(如94 、 37和13ghz ) 。
