摘要：

The thermodynamic temperatures of silver, gold and copper-silver eutectic fixed points were measured with a photoelectric pyrometer relative to an aluminum point of 660. 302 degree C. The values obtained were (961. 744 plus or minus 0. 055) degree C, (1064. 145 plus or minus 0. 060) degree C and (779. 583 plus or minus 0. 060) degree C respectively. Although the final uncertaint of the copper-silver eutectic was similar to that of the other two, the effort necessary to obtain it was much greater and it is not recommended as a major reference point for use in photoelectric pyrometry.
