其中Ws是核磁管内氚代试剂的质量；Ax为样品峰面积；As为内标物峰面积；E为样品在该化学位移处的质子当量即样品分子量产生该共振峰的基团中的质子数；Es为内标物在该化学位移处的质子当量。用于电催化的 BmimBF4CH3CN电解质溶液催化前后的核磁结果见图2-3。翻译成专业学术英语

Among them, Ws is the mass of tritium substitute in the NMR tube; Ax is the peak area of the sample; As is the peak area of the internal standard; E is the proton equivalent of the sample at that chemical shift, that is, the molecular weight of the sample divided by the number of protons in the functional group that generates the resonance peak; Es is the proton equivalent of the internal standard at that chemical shift. The NMR results before and after catalysis of the [Bmim]BF4/CH3CN electrolyte solution used for electrocatalysis are shown in Figure 2-3
