摘要: Recombinations in the ionized columns generated by faint radar meteors are observed as: (1) A rapid loss of returned signal first few milliseconds after formation column; (2) an apparent absence bright, low meteors; and (3) anomalies diffusion rates. Recombination at rates characteristic dissociative recombination atmospheric molecules N2(+) O2(+) is completely consistent with observations. It appears either that initial column or there charge exchange. a sufficient cause for differences between measures other studies.
