模拟结果显示，温度在20~80K之间，考虑热膨胀时的导热系数比晶格常数固定时的值要低，但随温度变化的关系更加接近实验值时的情况；比较固体氩中不同掺杂时导热系数大小，发现同样掺杂浓度条件下，掺空穴时材料导热系数比掺氪时低，说明掺杂时由于晶格不匹配引起的声子散射比不同质量引起的散射更重要。

Crystal lattice constants are close to other experiment results. Three kinds of chemical bonds exist among Mg and B atoms, between magnesium and boride is ionic bond and metallic bond is the predominant interaction in the layer formed by magnesium atoms. A strong covalent bond in the form of sp2 hybrid between boride atoms is the most important factors which can affect the transition temperature of MgB2. Population analysis clearly shows that electrons are transferred from Mg to B, as a result, the electron-phonon coupling in the layer of B is very strong.
