| 摘要: |
| 采用3种材料(第1种以有机硅为主要成分并引入氟碳化合物；第2种是质量分数分别为30%和70%的Remmers300和酒精；第3种是质量分数分别为30%和70%的硅烷单体和酒精)来加固石质文物样品，然后用单边核磁技术探测样品0，3，5mm深度剖面的孔隙率、孔径分布.结果发现：经过加固处理的样品孔隙率有所减小，同时具有较小的含水率；用第1种和第3种材料加固的样品其渗透加固效果较好，但通过三维形貌仪分析发现，第3种加固材料使样品表面形貌及颜色改变较大.综合比较后得出，第1种加固材料较为理想. |

| Abstract: |
| Three kinds of materials (organic silicon as the main component and the introduction of fluorocarbon compounds; mixture of 30% Remmers300 and 70% alcohol,the mixture of 30% silane monomer and 70% alcohol) were used to consolidate the stone samples, and then use mobile single sided NMR(nuclear magnetic resonance) technology to detect porosity, pore size distribution of samples at depth profiles of 0, 3, 5 mm. The results show that the porosity of samples and the water content were reduced after consolidation, the first and the third kind of consolidation materials penetrate better than the second. Through three dimensional morphology analysis, the third kind of consolidation material changes color and surface topography of the sample changes significantly. Comprehensive comparison shows that the first kind of consolidation material is more desirable. |
