我们制备了一种氦 - 3和氦 - 4的人工混合物，用作对源自地球地幔的样本进行精确的氦 - 3/氦 - 4测量的内标。该混合物被命名为HESJ（日本氦标准）。HESJ的氦 - 3/氦 - 4比值是通过获取日本四个实验室的五台仪器重复分析的加权平均值来确定的。HESJ的氦 - 3/氦 - 4比值相对于空气值（R/Ra）的推荐值为20.63 ± 0.10。所有研究人员均可获取HESJ。
We have prepared an artificial mixture of 3 He and 4 fie to be used as an internal standard for precise He-3/He-4 measurements of terrestrial mantle-derived samples. The mixture is named HESJ (He Standard of Japan). The He-3/He-4 ratio of HESJ was determined by obtaining the weighted average of repeated analyses from five machines in four laboratories in Japan. The recommended value of the He-3/He-4 ratio of HESJ relative to the air value (R/Ra) is 20.63 +/- 0.10. HESJ is available to all researchers.
