| Abstract: | As an advanced characterization method, time domain nuclear magnetic resonance (TD-NMR) technology can quickly and accurately measure the dynamic changes of free water and bound water in wood, and can also characterize wood pore distribution based on the moisture information. Therefore, it has been widely used in wood research. This paper concluded the methods of using TD-NMR to measure wood moisture content, water states, water distribution and wood pore distribution, and reviewed the main research results, with a view to providing theoretical basis for the research and application of related fields. |
