Palladium-hydrogen system has the largest isotope effect in the metal - (hydrogen) systems so far as we know, so palladium is widely used in hydrogen isotopes (disposal) technology.

在迄今所知的金属-氢体系中，钯氢体系的同位素效应最强，因此，钯被广泛用于氢同位素处理工艺中。

From the Angle of physical organic Chemistry, the transition state of chemical reactions has been studied in chemical reaction rate and isotope effect.

本文从物理有机化学的角度，从化学反应速度和同位素效应二方面对化学反应中的过渡状态问题进行探讨。

"It's the first time the same isotope has been used in two different experiments at two different labs, and it showed basically the same effect, " Prof Fischbach said.
