This paper is devoted to the results concerning NO, NO(2), and HNO(3) obtained during airborne experiments performed in June-July 1973 on Concorde 001. The altitude of flight was about 16 km. Results concerning NO are, within the accuracy of measurement, in agreement with results of a previousspectrometric balloonborne experiment conducted jointly by IASB and ONERA (14 May 1973). Nitric oxide is concentrated in stratospheric layers clearly above the flight altitude. Integrated amount of NO along the optical path is (4 +/- 1.5) x 10(16) mol cm(-2) for a solar elevation varying from +2 degrees above the horizontal plane to -1 degrees . A value of 6 x 10(8) mol cm(-3) may be given as an upper limit for the local concentration at the flight altitude. Thereis no significant difference in the integrated amount observed at sunset and sunrise. Measured value of NO(2) local concentration at 15.5 km is (1.1 +/- 0.2) x 10(9) mol cm(-3), in sunset conditions. This value is not greatly modified between 15 km and 30 km. Measured value of HNO(3). This value increases with altitude between 15 km and 20 km. The local concentration is maximum at 20 km. The measured value is (2 +/- 1) x 10(10) mol cm(-3) at 20 km. It seems that local concentration decreases rapidly above 20 km.
本文致力于介绍1973年6月至7月在协和001号飞机上进行的空中实验中获得的有关一氧化氮（NO）、二氧化氮（NO₂）和硝酸（HNO₃）的结果。飞行高度约为16千米。在测量精度范围内，有关NO的结果与IASB和法国国家航空航天研究院（ONERA）于1973年5月14日联合进行的先前光谱气球实验结果一致。一氧化氮集中在明显高于飞行高度的平流层中。对于太阳高度从高于水平面2度到低于水平面1度的变化，沿光路的NO积分量为(4±1.5)×10¹⁶摩尔·厘米⁻²。飞行高度处的局部浓度上限可为6×10⁸摩尔·厘米⁻³。日落和日出时观测到的积分量没有显著差异。在日落条件下，15.5千米处NO₂局部浓度的测量值为(1.1±0.2)×10⁹摩尔·厘米⁻³。该值在15千米至30千米之间变化不大。HNO₃的测量值。该值在15千米至20千米之间随高度增加。局部浓度在20千米处最大。20千米处的测量值为(2±1)×10¹⁰摩尔·厘米⁻³。似乎在20千米以上局部浓度迅速下降。
