摘要小巧、可移动的单面核磁共振传感器在对隐藏的壁画模型进行实验室测试后，研究人员在意大利沃尔特拉的Villa Palagione别墅和Seminario Vescovile di Sant‘Andrea研究了隐藏的壁画、油漆和砂浆层。确定了不同的油漆和砂浆层，并在可获得的情况下进一步用便携式X射线荧光光谱进行了表征。在从Volterra的Fortezza Medicea分离和修复的壁画“La Madonna della Carcere”中，油漆和砂浆层被区分开来，将分离的壁画固定在其支撑物上的粘合剂的水分含量在修复和原始部分都有差异。这些研究鼓励使用便携式单面核磁共振技术对历史城墙的层状结构和保护状态进行无损研究。

AbstractA compact and mobile single-sided 1H NMR sensor, the NMR-MOUSE®, has been employed in the nondestructive characterization of the layer structure of historic walls and wall paintings. Following laboratory tests on a model hidden fresco, paint and mortar layers were studied at Villa Palagione and the Seminario Vescovile di Sant’ Andrea in Volterra, Italy. Different paint and mortar layers were identified, and further characterized by portable X-ray fluorescence spectroscopy where accessible. In the detached and restored fresco “La Madonna della Carcere” from the Fortezza Medicea in Volterra, paint and mortar layers were discriminated and differences in the moisture content of the adhesive that fixes the detached wall painting to its support were found in both restored and original sections. These investigations encourage the use of the portable and single-sided NMR technology for nondestructive studies of the layer structure and conservation state of historic walls.
