我们用集成量子电压噪声源（IQVNS）作为参考的约翰逊噪声温度计（JNT）测量了镓的熔点热力学温度T_{\mathrm {Ga}}$。$T_{Ga}$是使用科学和技术数据委员会（CODATA）为修订国际单位制（SI）而推荐的基本常数计算的。测量的T_{Ga}$与1990年国际温标定义的值一致。
We measured the thermodynamic temperature of the melting point of gallium $T_{\mathrm {Ga}}$ using a Johnson noise thermometer (JNT) with an integrated quantum voltage noise source (IQVNS) as a reference. $T_{\mathrm {Ga}}$ was calculated using the fundamental constants recommended by the Committee on Data for Science and Technology (CODATA) for the revision of the International System of Units (SI). The measured $T_{\mathrm {Ga}}$ is consistent with the value defined in the International Temperature Scale of 1990.
