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.

采用核磁共振谱法测定了国产紫胶桐酸的优,结果表明,其分子中连二羟基处于反交位。

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，一个长途旅行的艺术品组携带着许多高科技仪器：一架原子力显微镜、一台核磁共振松弛测量仪。
