摘要：【中文】本发明涉及一种基于低场核磁共振技术的卷烟保润性能评价方法。所述评价方法包括如下步骤：将两组烟丝样品进行平衡等处理后得两组待测烟丝样品；然后利用低场核磁共振技术测定两组烟丝样品的样品信号值，并根据反演信号，比较T₂₁的大小，T₂₁较小的烟丝样品保润性能优于T₂₁较高的烟丝样品。本发明利用低场核磁共振技术对卷烟保润性能进行评价，操作简便、耗时较短，可快速有效地达到保润性能评价的目的；并且具有无损检测的优点，避免了原料的浪费与污染，减少了开发过程中的物料损耗、降低研发成本、提高工作效率。 【EN】The invention relates to a cigarette moisture retention performance evaluation method based on a low-field nuclear magnetic resonance technology. The evaluation method comprises the following steps: balancing the two groups of tobacco shred samples to obtain two groups of tobacco shred samples to be detected; then, the low-field nuclear magnetic resonance technology is utilized to determine the sample signal values of the two groups of tobacco shred samples, and the T is compared according to the inversion signals₂₁Size of (D), T₂₁Smaller tobacco shred sample has better moisture retention performance than T₂₁Higher tobacco samples. The method utilizes the low-field nuclear magnetic resonance technology to evaluate the moisture retention performance of the cigarettes, is simple and convenient to operate, consumes short time, and can quickly and effectively achieve the purpose of evaluating the moisture retention performance; the nondestructive testing device has the advantages of nondestructive testing, avoids waste and pollution of raw materials, reduces material loss in the development process, reduces research and development cost and improves working efficiency.
