摘要：

The behavior of induction signals during steady-state pulse irradiations in N-14 NQR was investigated experimentally. It has long been known that the signal response to a long sequence of rf pulses will dramatically increase for pulse spacings less than T2. This increase is exponential, and can result in signals comparable to optimally prepared Free Induction Decays. Because these "SORC" signals recur as long as the pulsing continues, very efficient signal-averaging can result. The dependence of these quasi steady-state signals on pulse parameters and on frequency offset are presented, together with a discussion of the applicability of the method.
