摘 要:通過直接對內插方程求導,獲得了0.01~961.78℃分溫區的傳播不確定度方程。其靈敏度系數的基本結構與內插方程相同,仍然是組成原內插方程的基礎函數的線性組合,但組合系數不同,且仍是一分段函數。[著者文摘]

Equations of Propagation of Uncertainty on ITS-90 in the Sub-range from 0.01 to 961 .78 ℃FU Guang-sheng, KANG Zhi-ru 1.Hebei University, Baoding, Hebei 071002, China; 2. Hebei Provincial Institute of Metrology, Shijiazhuang, Hebei 050051, ChinaAbstract:By direct differentiation with respect to the ITS-90 interpolation equation in the sub-range from 0.01 to 961.78℃, equations of propagation of uncertainty on ITS-90 in the above range are given. Its sensitivity coefficients are also linear combinations of basic functions comprising the interpolation only with different constant, and are still sectional functions.[著者文摘]
