用一个简单的平均场晶格气体模型预测了在低氢压下只吸收少量氢的铬、锰、铁、钴、镍、钼、Ru、Rh、Ir、W、铂、铜、银和金的氢化物生成性质。结果表明，仅根据低压数据(摩尔标准生成热Hx0和间隙氢振动的爱因斯坦温度θE)确定的热力学参数也可以描述它们的高压行为。结果，给出了这14种金属在不同温度和1Mbar压力下的压力-组成等温线。在可能的情况下，与实验数据进行了比较。
A simple mean-field lattice gas model is used to predict the hydride formation properties of Cr, Mn, Fe, Co, Ni, Mo, Ru, Rh, Ir, W, Pt, Cu, Ag and Au, which at low hydrogen pressures absorb only small amounts of hydrogen. It is shown that with thermodynamic parameters determined from low-pressure data only (the molar standard heat of formation Delta H x 0 and the Einstein temperature Theta E of the interstitial hydrogen vibration) it is also possible to describe their high-pressure behaviour. As a result, the pressure-composition isotherms of these 14 metals are given for several temperatures and for pressures up to 1 Mbar. Where possible, comparison is made with experimental data.
