我个人认为你说的意思是“composition”和“constituent”的区别,具体到这两个单词在金属学中的区别,下面这段话讲的比较清楚,
“The composition of a system is defined as the amount of each element or component in the whole system, and the constitution of a phase is defined as the amount of each constituent or species on a specific sublattice of the phase. ”希望能有助于你的理解
