摘　　要：过去二十多年,多接收电感耦合等离子体质谱技术(MC-ICP-MS)和相关化学纯化方法取得重要突破,使得高精度分析同位素的微小分馏成为可能。这一技术的进步极大地推动了非传统稳定同位素在环境科学、地球科学和行星科学领域的应用。同时,在不同温度和压力条件下(模拟地球和其他行星的内部环境)开展的同位素分馏实验,可以为研究人员提供同位素分馏机制的直接观察数据,故而同位素高温高压实验研究受到越来越多的重视。本文介绍了非传统同位素高温高压实验常用的装置,以及用于判断实验产物中的同位素平衡状态的方法,并对铁、硅、铬、镍、钒等同位素在高温高压实验领域的研究成果进行了梳理,以期为相关研究提供更多的参考。Over the past two decades,the significant breakthroughs in multi-collector inductively coupled plasma mass spectrometry(MC-ICP-MS)and chemical purification methods make it possible to measure small isotope fractionations with high precision.These technological advances have greatly promoted the application of non-traditional stable isotopes in the fields of environmental science,geosciences,and planetary science.In the meantime,experimental studies on the isotope fractionation conducted under different temperature and pressure conditions(simulated internal environments of the Earth and other planets)have become increasingly crucial,as they can provide direct experimental observations on isotope fractionation behaviors and mechanisms.In this article,we have summarily introduced commonly used equipments for high-temperature and high-pressure experimental studies on non-traditional isotopes and detailed methods for determining isotope equilibrium states of those experimental products,then have reviewed research progresses and achievements in the field of high-temperature and high-pressure experimental studies on fractionations of non-traditional isotopes of iron,silicon,chromium,nickel,and vanadium,in order to provide more references for relevant researchers.
