I researched Japan/China identification of methamidophos as bothered "poisoned gyoza". For high precision and accuracy, the many reagents in combustion tube were tested. As the results, the copper oxide with nickel and platinum was selected. In addition, I installed cryofocusing system using liquid nitrogen between combustion and IRMS and can analyze low concentration of methamidophos. Finally, Chinese methamidophos pesticide is very closed to a methamidophos reagent bought in Japan by using δ^<13>C.

我研究了日本/中国将甲胺磷鉴定为“有毒的饺子”。为了提高准确度和精密度，对燃烧管中的多种试剂进行了测试。作为结果，选择具有镍和铂的氧化铜。此外，我在燃烧和IRMS之间安装了使用液氮的低温聚焦系统，可以分析低浓度的甲胺磷。最后用δ^ C法测定了我国甲胺磷农药与日本甲胺磷试剂的接近<13>程度。
