摘要：

Aluminium samples were doped with an assortment of impurities and the shifts of their equilibrium melting curves were determined under static adiabatic experimental conditions. The shift of run-off temperatures (i.e. when the sample temperature breaks off from the melting 'plateau' and rapidly begins to rise) of originally 99.9999% pure Al samples caused by impurities was determined to be as follows (in millikelvin per part per million (ppm) by weight): Ag, -0.12; Zn, -0.16; Cu, -0.29; Fe, -0.35; In, -0.21; Quartz, -0.33; Si, -0.66; Ti, +3.30; Mn, -0.063; Cd, -0.10; Sb, -0.19; Ca ?; Ni, -0.43.
