The larger the atomic volume construction,the higher the stability of intermediate phase.There exist 4 eutectic systems with 9 eutectic reactions in Au-RE systems.A criterion exists between the reduced eutectic temperatureand the atomic radiiof RE metals:the Teu/TA values dedine linearly with the increase of rR Value and keep essentially a constant when rRE values are larger than 0.175nm (namely the atomic size differences between RE and Au are larger than 21%).

Au-RE系中存在4个共晶系9种共晶反应，简约共晶温度与RE原子尺寸之间存在一个判据：简约共晶温度随RE原子半径增大呈线性下降，但当RE原子半径达到约0.175nm(即与Au相对尺寸差21％)时，更大原子尺寸差不再影响液相线和共晶温度下降，简约共晶温度保持常数。
