| titleOfInvention | A method for measuring transverse relaxation rate of wood cell wall pore surface |
| abstract | The invention relates to a method for measuring the transverse relaxation rate of a pore surface of a wood cell wall, which comprises the following steps: (1) sequentially performing heat treatment and water-saturated treatment on a wood sample to obtain a water-saturated sample; (2) using time-domain nuclear magnetic resonance Spectrometer is used to measure the transverse relaxation time distribution curve of the saturated sample, and curve 1 is obtained; (3) the wood sample after the measurement in step (2) is dried to absolutely dry, and then the gas adsorption pore size is measured, and curve 2 is obtained; (4) Calculate based on the data of curve 1 and curve 2 to obtain the transverse relaxation time value corresponding to the gas adsorption aperture under the same cumulative distribution frequency, and obtain curve 3; (5) Combine curve 2 and curve 3 to obtain the wood test. The distribution nodes of different pore systems within the pore size range of the cell wall of the sample are determined, the conversion coefficients between the nodes are determined, and the surface transverse relaxation rates of the different pore systems of the cell wall of the wood sample are determined. |
