  1. 摘要环境测信号经常遭遇外在杂讯的干扰,诸如测电缆线受电磁干扰及遥测信号解调失眞等,而使眞实量测信号与杂讯混淆。
    Environmental measuring signals are often interfered by exterior noise which always resulted from the EMI or decoding distortion of telemetry.
  2. 研究了探测场或驱动场失谐情况下开放的Λ型无粒子数反转激光系统中原子响应的时间演化规律,并与探测场和驱动场都共振时的演化规律进行了比较.我们发现失谐对时间演化规律有显著的影响;当驱动场或探测场失谐时,原子对探测场和驱动场色散的响应不再为零,双光子相干不再是纯实量;探测场失谐的变化将使粒子布居和驱动场增益(吸收)的时间演化规律明显改变;随着失谐的增大,探测场增益(吸收)、色散和双光子相干随时间的演化行为逐渐偏离标准阻尼振子的演化规律;驱动场色散驱动场失谐的增加而振荡时间变长,振幅和稳定值变大.
    We study the time evolution law of the atomic response in an open Λ-type inversionless lasing system when the probe or driving field is off-resonance,and compare the law with that obtained when the probe and driving fields are resonant.We find that the detuning has considerable effects on the time evolution law:When the probe or driving fields is off-resonance,the dispersive responses for the probe and driving fields are no longer 0 and the two-photon coherence is no longer a pure real;The variation of the probe detuning can make the time evolution law of the population distributions and the gain (absorbtion) of the driving field changing obviously;With detuning increasing,the time evolution behavior of the gain (absorbtion),dispersion of the probe field and the two-photon coherence will gradually diviate from the evolution law of the standard damped oscillator;With the driving detuning increasing,the oscillating time of the dispersion of the driving field becomes longer,the amplitude and the stationary value increase.
