It is shown that thetemperature coefficient of surface tension is negative, being -0.470 dyne/cm·℃ at1100-1500℃. A maximum was observed on the surface tension-temperature curve at1350℃, indicating an apparent positive coefficient up to this temperature. This is ex-plained by the presence of residual surface active impurities in the original sample whichlowered the surface tension, and the removal of such impurities during heating. 收稿日期: 1965-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 严铄 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1965/V8/I2/251 [1] Turnbull, D.: J.
