采用液滴振荡法测量了铜熔体的表面张力。简化了液滴在下落过程中的表面振荡，并利用瑞利方程计算了液滴的表面张力。测量在包括过冷状态的宽温度范围内进行。铜的表面张力γ = 1257 - 0.20（T - 1356）（mNm（-1））（T = 1287-1998 K）。
The surface tension of molten copper was measured by the oscillating drop method using a falling droplet. The surface oscillation of the droplet was quite simplified during the falling, and consequently, the surface tension was calculated using Rayleigh's equation. The measurements were carried out in a wide temperature range including the undercooling state. The obtained surface tension of copper is expressed as follows:gamma = 1257 - 0.20(T - 1356) (mN m(-1)) (T = 1287-1998 K).
