It is discovered that the observed 14N remote NQR signal intensity is strongly dependent on the strength of off-resonance and reaches its maximum value when the offset is close to the rf field strength. This dependence of signal intensity upon off-resonance may be used to increase the sensitivity of the 14N remote NQR spectrometer. The result is discussed and explained theoretically by the numerical calculation of pulse excitation bandwidth.             本文对遥测NQR谱中的偏离共振效应作了较详细地研究,发现~(14)N谱线的强度随偏离共振效应而变化。当偏离共振强度与射频场强度接近时,测得的谱线强度最大。该效应可用来增强~(14)N遥测NQR谱仪的灵敏度。上述实验现象在理论上采用脉冲的激发带宽方法作了解释和讨论。 文摘来源   << 更多相关文摘         相关查询: 带宽 激发 外存带宽 风激发 激发理论 度量带宽 频谱带宽 带宽估测 激发函数． 带宽划分 准带宽 激发策略  对查询结果不满意
