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.

• 实验表明,在TE_(011)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。
