摘　　要：本文提出一种利用含水量的定量调制测定重水氘代率的核磁共振(NMR)实验方法,并通过实验和推理为所建实验方法提供理论依据。该方法操作环节少,易于定量操控,因而所得结果可信度高。实际样品的测量表明可满足普通核磁共振实验室对重水试剂评估的要求。Here, an NMR method, combining with the quantitative adjustment of water content, was suggested for the determination of the deuterated yield of Heavy This method was well supported by the experimental and theoretical analysis. Since there were only few steps involved, the experiment was easy to be handled quantitatively, and so that the result obtained should be reliable. The real sample test showed that this method can meet with the requirement for the evaluation of heavy water in normal NMR Labs.
