| 中文摘要:采用低场核磁共振分析技术（LF-NMR）对不同来源水处理后的烟丝进行分析，研究了不同处理工艺样品的含水率及水分分布状态的变化。结果表明：水的种类对烘丝关键工序烟丝水分含量及分布状态具有明显影响。其中反渗透水和磁化水处理的样品含水率高于自来水处理后的样品，分别高0.43%和0.72%。得到薄板适宜的加工温度为140~150 ℃，气流干燥适宜的加工温度为180~210 ℃。 |

| Study on Different Kinds of Water Distribution and Moisture Content in Tobacco by LF-NMR Technique |

|
| Abstract:The pipe tobacco processed with different kinds of water was analysed by low field nuclear magnetic resonance（LF-NMR） technique.The moisture content and changes of water distribution in the samples treated by different processes were studied in detail.The study result showed that the water species has a significant influence on the pipe tobacco processed by moisture content and its distribution.The total moisture contents of the samples treated with reverse osmosis water and magnetized water are generally 0.43% and 0.72% higher than that with tap water,respectively.The appropriate KLK processing temperature is in the range of 140-150 ℃，and the appropriate HXD processing temperature is 180-210 ℃. |
