铁虫 (小有名气)

[求助] 论文摘要里两个关键词没见过,谁能解释一下啊?

Acta Materialia;Volume 59, Issue 4, February 2011, Pages 1577–1585
The integrated diffusion coefficient of the phases and the tracer diffusion coefficients of the species are determined in the Nb–Si system by the diffusion couple technique. The diffusion rate of Si is found to be faster than that of Nb in both the NbSi2 and Nb5Si3 phases. The possible atomic mechanism of diffusion is discussed based on the crystal structure and on available details of the defect concentration data. The faster diffusion rate of Si in the Nb5Si3 phase is found to be unusual. The growth mechanism of the phases is also discussed on the basis of the data calculated in this study.
首句里面有个 integrated diffusion coefficient 和 tracer diffusion coefficients不知道啥意思啊?

谁能帮忙解答一下

integrated  是综合 累计的意思  后面的是扩散系数;tracer 是跟踪的意思 是不是所学的学科里有这方面的名词?
