But inside, a hard-traveling team of art conservators packs an arsenal of high tech gear: an atomic-force microscope, a micro-Raman spectroscope, a nuclear magnetic resonance relaxometer.

但在其内部，个长途旅行的艺术品保护小组携带着许多高科技器：子力显微镜、核磁共振松弛。

Nuclear magnetic resonance techniques are used to determine the national aleutric acid preferential conformation. The results show that the dithionic hydroxyl radicals are in reciprocal cross bearing.

采用核磁共振谱法定了国产紫胶桐酸的优势构象,结果表明,其分子中连二羟基处于反交叉位。
