| 摘 要： | 从电磁波传播的基本理论出发,分析了微波在含有石墨碳的灰分中的传播,推导了电磁波在含碳的灰分介质中的幅度衰减和相位变化关系,提出一种新的利用微波测量烟道灰分中碳含量的方法,按该方法设计制作了相应的实验装置并获得了与理论分析一致的实验结果.

| Abstract: | Based on the theroy of electromagentic wave,the microwave propagation in fly ash containing unburnt graphite carbon has been analysed.According to the amplitude attenuation and phase shift of the microwave transmitted through fly ash, a new method and apparatus is developed to measure unburnt carbon content of fly ash. The experiment results matched well with the theoretic analyses. |

| Keywords: | unburnt graphite carbon microwave amplitude phase fly ash medium |
