熔融 LiF-NaF-KF、LiF-BeF2 和 Li2CO3-Na2CO3-K2CO3 粘度的参考相关性

1974 年，Janz 提出了熔融 LiF-NaF-KF、LiF-BeF2 和 Li2CO3-Na2CO3-K2CO3 粘度的参考关系式，并从那时起得到广泛应用。然而，在过去的 45 年中，已经发表了许多其他测量结果。这就是为什么在本文中，提出了这些盐的粘度的新参考相关性。这三种熔盐的粘度的所有可用实验数据都经过严格检查，目的是建立改进的或新的参考粘度相关性。根据一系列标准规定的测量质量，将所有实验数据分为初级数据和次级数据。为 LiF-NaF-KF 提出的参考相关性，在 95% 置信水平下的不确定性为 2.9%，将先前相关性的温度范围从 (770–970) K 扩展到 (732–1163) K 并保留其不确定性。为 LiF-BeF2 提出的相关性在 95% 的置信水平下具有 4.9% 的不确定性，将先前相关性的高温范围从 (740–870) K 扩展到 (793–1573) K，但在它的不确定性。然而，它是一种更好的相关性，因为它基于上一次测量时不可用的测量结果。最后，Li2CO3-Na2CO3-K2CO3 的参考相关性，不确定度为 3%，也将先前相关性的温度范围从 (920-1170) K 扩展到 (738-1170) K 并保留其不确定性。 1974 年， Janz 提出了熔融 LiF-NaF-KF、LiF-BeF2 和 Li2CO3-Na2CO3-K2CO3 粘度的参考相关性，并从那时起被广泛使用。然而，在过去的 45 年中，已经发表了许多其他测量结果。这就是为什么在本文中，提出了这些盐的粘度的新参考相关性。这三种熔盐的粘度的所有可用实验数据都经过严格检查，目的是建立改进的或新的参考粘度相关性。根据一系列标准规定的测量质量，将所有实验数据分为初级数据和次级数据。为 LiF-NaF-KF 提出的参考相关性在 95% 置信水平下的不确定性为 2.9%，将先前相关性的温度范围从 (770–970) K 扩展到 (732–1163) K 并保留其不确定性. 为 LiF-BeF2 提出的相关性，在 95% 置信水平下具有 4.9% 的不确定性，... 在过去的 45 年中，发表了许多其他测量结果。这就是为什么在本文中，提出了这些盐的粘度的新参考相关性。这三种熔盐的粘度的所有可用实验数据都经过严格检查，目的是建立改进的或新的参考粘度相关性。根据一系列标准规定的测量质量，将所有实验数据分为初级数据和次级数据。为 LiF-NaF-KF 提出的参考相关性在 95% 置信水平下的不确定性为 2.9%，将先前相关性的温度范围从 (770–970) K 扩展到 (732–1163) K 并保留其不确定性. 为 LiF-BeF2 提出的相关性，在 95% 置信水平下具有 4.9% 的不确定性，... 在过去的 45 年中，发表了许多其他测量结果。这就是为什么在本文中，提出了这些盐的粘度的新参考相关性。这三种熔盐的粘度的所有可用实验数据都经过严格检查，目的是建立改进的或新的参考粘度相关性。根据一系列标准规定的测量质量，将所有实验数据分为初级数据和次级数据。为 LiF-NaF-KF 提出的参考相关性在 95% 置信水平下的不确定性为 2.9%，将先前相关性的温度范围从 (770–970) K 扩展到 (732–1163) K 并保留其不确定性. 为 LiF-BeF2 提出的相关性，在 95% 置信水平下具有 4.9% 的不确定性，...
