摘　　要：衰变系数是计算Re-Os同位素年龄的重要参数。研究者在将采用不同衰变常数计算获得的Re-Os同位素年龄进行比对时,容易忽视衰变系数变更引起的Re-Os同位素年龄变化。本文提出了采用不同衰变系数的Re-Os同位素年龄之间的换算方法,指出了该换算方法的使用原则和要点。The decay coefficient is an important parameter to calculate the age of the Re-Os isotopic age. When the researchers compared Re-Os isotopic ages obtained by using different decay constants, it was easy to ignore the change of Re-Os isotope age caused by change of decay coefficient.In this paper, a conversion method of Re-Os isotope ages with different decay coefficients was proposed, and the using principles and key points were pointed out.
