请问分子光谱线里的signature这个词作什么意思讲？

最近看的一些文献经常有signature这个词，不知道作什么意思讲比较好。因为不是熟悉的领域，所以来请教大家，比如characteristic signatures 这种说法。。。 举一篇文章为例 CO2 Laser Signature Problem Abstract A CO2 laser may oscillate at any one of many possible lines. As the cavity length of such a laser is varied over a distance of λ/2, a large number of lines oscillate one at a time in succession. The listing of the identities of the sequences of lines constitutes a signature of the laser and is a matter of practical importance in the operation of these lasers in remote controlled applications without the use of mode-selecting elements in the cavity of the laser. We report here a rather remarkable result, namely, that the lines P(20) and P(16) of the 10.4-μm band compete so effectively relative to all the other modes that they can be relied on to oscillate over quite a wide gain curve and for a wide range of operating conditions. 嗯，我只想知道Signature 到底是啥东东呢。。。 |
