建立了一项选择自旋翻转回波￣Ｈ核磁共振技术。该技术的重要特点之一是能够直接测定普通水和某些生物样品中微量的毒物药物及其降解产物，并且结果准确可靠，目前在毒物分析和药物代谢等领域中已得到了应用。 A spin-echo selective 1H nuclear magnetic resonance technique was established. One of the important features of this technique is the ability to directly measure trace amounts of poisons and their degradation products in ordinary water and in certain biological samples, and the results are accurate and reliable. At present, it has been applied in the fields of toxicology analysis and drug metabolism.
