Different discretizations methods applied to models of core/mantle segregations are tested (single stage, multistage accretion, results of N-body simulations) in order to test the sensitivity of the thermo-chemical coupling to the type of discretization used. We found that while single stage and large discretization of segregation steps yield very different core temperature, multistage models of accretion and core mantle segregation, at least for the model presented in this paper, tend to yield similar results, whether it is for the light element concentrations or the final temperature of the core. As long as a magma ocean existence throughout the entire process of core/mantle segregation is posited, and that only the impactor's masses of metal and silicate are re-equilibrated at each step, the degree of discretization of continuous model does not matter as long as it encompasses more than 10 steps of calculations.

模拟吸积核热化学历史时离散化选择的影响

测试了应用于核心/地幔分离模型的不同离散方法（单阶段、多阶段吸积、N体模拟结果），以测试热化学耦合对所使用的离散类型的敏感性。我们发现，虽然单阶段和大离散的分离步骤产生非常不同的核心温度，但吸积和核心地幔分离的多阶段模型，至少对于本文提出的模型，往往会产生相似的结果，无论是对于轻元素浓度或核心的最终温度。只要假定岩浆海存在于整个核/幔分离过程中，并且在每一步中只有撞击体的金属和硅酸盐质量重新平衡，那么连续模型的离散程度并不重要，只要它包含10多个计算步骤。
