"I think this paper nicely demonstrates that flies can tell deuterated and non-deuterated odors apart," she says.

“我认为这篇论文只是很好地表明果蝇可以分辨氘和非氘气味，”她说。

Furthermore, by the method of FTIR, 1H NMR and GPC, the deuterated ratio and structure ofd-PE have been characterized.

并通过红外、固体核磁共振以及高温凝胶渗透色谱（GPC）等途径对产物的纯度及氘代率进行了表征。

When PVP or HCO-60 was added to a deuterated chloroform solution of nitrazepam, the 1H-NMR signals of N (1 )-H shifted to lower magnetic fields.

PVP等在氘代氯仿中可使硝基安定1位氢的核磁信号向低磁场方向位移。PVP与硝基安定的相互作用比HCO-60等要强。
