| 摘 要： | 实验表明,在TE011模式园柱形腔中,不但可以使用扁平样品管测量水溶液样品的ESR波谱,而且获得好的腔品质因子Q和高品质的ESR信号。所观察到的信号高度,是使用最佳尺寸毛细管样品时最大信号高度的3.2倍;又是在具有波导尺寸的TE102腔中使用扁平样品管时所获得信号高度的3倍。本文对此作了定性的理论分析。 |

| Abstract: | The experimental results show that flat sample cell not only can be used to measure ESR spectrum of aqueous sample in a TE011 mode cylindrical cavity,but also gives a good cavity quality factor Q and high quality ESR signals. The observed signal height was 3.2 times as large as the maximum signal height that can be obtained when a capillary tube with optimum size was used in the same cavity, and 3 times as large as the signal height when a flat cell was used in a TE102 mode rectangular cavity with waveguide size. In this paper,a theoretical analysis is given. |
| Keywords: | electron spin resonance(ESR) sensitivity of ESR spectrometer TE_(011) mode cylindrical cavity flat sample cell. |
