Stable isotope ratio variations are regulated by physical and chemical laws. These rules depend on a relation with mass differences between isotopes. New classes of isotope variation effects that deviate from mass dependent laws, termed mass independent isotope effects, were discovered in 1983 and have a wide range of applications in basic chemistry and nature. In this special edition, new applications of these effects to physical chemistry, solar system origin models, terrestrial atmospheric and biogenic evolution, polar paleo climatology, snowball earth geology, and present day atmospheric sciences are presented.
稳定同位素比的变化受物理和化学规律的制约。这些规律取决于同位素质量差异的关系。1983 年发现了一类新的偏离质量依赖规律的同位素变化效应，称为质量独立同位素效应，它在基础化学和自然界中有广泛的应用。在这个特刊中，介绍了这些效应在物理化学、太阳系起源模型、地球大气和生物进化、极地古气候学、雪球地球地质学以及当今大气科学中的新应用。
