采用一种基于单质全局物态方程模型QEOS(quotidianequationofstate)的混合物态方程,计算了锂铅合金在给定温度与密度下的压强、电离度,并对电离平衡、不同温度密度下电子及离子对总压强的影响进行了分析。结果表明,高温或高密时电子压强占主要部分,等温线整体行为与电子等温线一致;在常温固体密度附近,由于电子成键作用,使得离子束缚在一起,当温度升高时进入相变区。 Using a mixed state equation based on the QEOS (Quasi State of State) model, the pressure and ionization of lithium-lead alloys at a given temperature and density were calculated. The effects of ionization and ionization on electron-ion pair The impact of total pressure was analyzed. The results show that the electron pressure accounts for the major part at high temperature or high density, and the overall behavior of the isotherm is consistent with that of the electron isotherm; near the solid density at room temperature, the ions are bound together due to electron bonding, .
