| 摘 要： | 讨论带参数的自适应时域方法计算极光系统的参数，以一个有理形式函数模型来代表系统函数，采用可以在线实时应用的递推自适应算法来确定该模型的参数。利用这种方法处理测量所得的极光亮度数据，现用互谱方法计算的氧原子「ＯＩ３２」跃迁时Ｏ（＾１Ｓ）态的平均有效寿命符合得很好。

| Abstract: | The parameters in auroral system are calculated using an adaptive parametric time domain approach. The adaptive algorithm, in which the system function is represented by a rational form model, allows on line real time application. The data processing illustrates that the effective mean lifetime of O ( 1S) thus determined, resulted from the OI 32 ] transition of atomic oxygen, is in accordance very well with the one evaluated in frequency domain. |
