中文摘要：

以Miedema半经验模型和比热容随温度有效形成热变化的经验公式为基础，结合基本热力学关系式对Fe-Sn和Ni-Sn体系的有效形成热及有效形成热随温度的变化进行了计算．采用电弧放电法制备了Ni-Sn和Fe-Sn纳米粒子．XRD结果表明，在Ni-Sn系中金属间化合物的初生相为Ni3Sna，而Fe-Sn系中出现的为FeSn2．计算结果与相应纳米颗粒体系的实验结果吻合较好．

英文摘要：

Based on Miedema semi-empirical model and an empirical specific heat equation, the effective heat of formation and its temperature dependence were calculated for Fe-Sn and Ni-Sn systems. Fe-Sn and Ni Sn nanoparticles were prepared by an arc discharge method and the formed phases were determined by X-ray diffraction （XRD）. Theoretically predicted primary intermetallic compounds were FeSn2 in Fe Sn system and Ni3Sn4 in Ni-Sn system, which are well consistent with the experimental results.
