摘要：

Gaseous negative ions were mass spectrometrically measured in the exhaust plume of a jet aircraft in flight. Using a quadrupole mass spectrometer operated in a high-pass mode, it was found that by far most of the ions had mass numbers > 450 amu (atomic mass units) and number densities which markedly exceeded the number densities of ambient atmospheric ions. The latter were observed outside the exhaust plume and had mostly mass numbers © Copyright 1999 by the American Geophysical Union.
