In this paper , the characteristics and the variation of these minor gases in the urban city ( beijing ) was studied by means of the data process and analysis and the discussion was made for the factors related to the variation 本文通过对这些资料的分析和计算，研究了最近几年这些微量气体在城市中的分布和变化情况，探讨了影响这些气体浓度变化的因素。
Furthermore , we design a more compact photoacoustic spectrometer based on a waveguide coi laser . 2 . the above systems are used to measure the ethylene production of apples , nectarines and cherry - tomatoes 微量气体光声光谱仪应用于生物学研究，分别测量了苹果，油桃以及樱桃西红柿等在不同成熟期或遭受胁迫状态下的乙烯产量，在揭示新的生物学规律方面做了有益的尝试。
Co2 laser - based differential absorption lidar ( dial ) systems have been used extensively for the remote sensing measurement of molecular species in the atmosphere and trace gases , therefore , have important value in military and civilian fields 基于二氧化碳激光器的差分吸收激光雷达（ co2dial ）系统被广泛地应用于对大气分子种类以及微量气体进行遥感的测量之中，具有非常重要的军事和民用价值。
The random error analysis of the method gives the relative deviation of 8 % - 10 % ) for the method of deriving co . it shows that the column content of co and other atmospheric minor gases can be well derived using this method , and the retrieval algorithm is very simple and effective 原理和数据分析表明，该测量方法可以较好地反演出大气co等微量气体的柱总量。对co大气柱总量的反演精度可达到8 - 10 。反演算法简单易用。
Some inpacts posed to ecological environment were also elucidated , such as adverse impact on human health and causes of odour problem etc . , and put torward that study of trace gases emitted from municipal sanitory landfill shouldd be paid great attention in china 阐明了微量气体的来源、产生和组成，论述了垃圾卫生填埋场微量气体对生态环境所产生的某些不良影响及其对人类健康的危害和所造成的恶臭问题等，提出要重视我国在填埋场微量气体方面的研究。
The dry atmosphere consists almost entirely of nitrogen ( 78 . 1 % volume mixing ratio ) and oxygen ( 20 . 9 % volume mixing ratio ) , together with a number of trace gases , such as argon ( 0 . 93 % volume mixing ratio ) , helium , and radiatively active greenhouse gases such as carbon dioxide ( 0 . 035 % volume mixing ratio ) , and ozone 干大气几乎完全由氮（ 78 . 1 %的体积混合比）和氧（ 20 . 9 %的体积混合比）构成，还包括一些微量气体，如氩（ 0 . 93 %的体积混合比） 、氦，以及对辐射起作用的温室气体如二氧化碳（ 0 . 035 %的体积混合比）和臭氧。
The co , water vapor , ch4 and other minor gases have been measured in beijing since 1996 by lageo , institute of atmospheric physics , chinese academy of sciences , using an infrared grating spectrometer of moderate resolution . the observation site locates on the roof of the building of the institute of atmospheric physics located in the right north between the 3rd and 4th circles . the co and water vapor column contents have been measured during autumn since 1996 , summers of 1997 and 1999 , and through 2003 , and ch4 column content for autumns of 1996 , 1998 , 2001 and 2002 自1996年以来，中国科学院大气物理研究所中层大气与遥感研究部利用中分辨率红外光谱仪系统，在北京市区北三环和北四环中路之间的中国科学院大气物理研究所主楼楼顶进行了co 、水汽和ch _ 4等大气微量气体柱总量的观测，获得每年秋季( 10 、 11月) ， 1997 、 1999年夏季和2003年一整年的co和水汽的资料： 1996 、 1998 、 2001和2002年秋季ch _ 4的资料。
As carbon monoxide , methane and nitrous oxide are active in atmospheric chemical processes , a change of the concentration of these species will affect the equilibrium of atmospheric chemical reactions and the balance of atmospheric species , implying the change of many other minor gases , including some pollutants such as ozone 大气中co 、 ch _ 4和n _ 2o等微量气体具有化学活性，它们在大气中浓度的变化影响着大气化学反应平衡和物质平衡，从而影响其他许多微量气体成分包括一些大气污染成分如臭氧的浓度分布及变化。
