Andrade 教授关于简单液体的滞性理论,和我们关于金属液体表面强力的理论模型,具有共同的基本假设,即同体熔解后(尤其在熔点附近温度)仍以原来特性频率继续振动。因此,根据这两个理论来研究金属液体在熔点时的滞性系数η_m 和表面张力 S_m 二者间的关系,显然是有趣的。Andrade 教授的熔点滞性公式为
Professor Andrade’s theory of hysteresis for simple liquids has the same basic assumption as our theoretical model for the surface strength of metallic liquids that the bulk continues to vibrate at its original characteristic frequency after melting (especially near the melting point). Therefore, it is obviously interesting to study the relationship between the hysteresis coefficient η_m and the surface tension S_m of molten metal at the melting point based on these two theories. Professor Andrade’s melting point hysteresis formula is
