The work describes the methods and procedures used to determine the wavelengths of minimum transmittance of holmium oxide in perchloric acid solution. Measurements of spectral transmittance of the solutions were made by means of a high precision spectrophotometer over the wavelength range 200 nm to 680 nm. The wavelength scale accuracy of this instrument was verified by extensive measurements of mercury and deuterium emission lines. The measurements of spectral transmittance of the holmium oxide solutions were made as a function of temperature, purity, concentration, and spectral bandwidth. Analysis of the uncertainties associated with these parameters and the uncertainties associated with the calibration of the instrument wavelength scale and the data analysis have resulted in an estimated uncertainty of ±0.1 nm for the determination of the wavelengths of minimum transmittance of the holmium oxide solution.
该工作描述了用于测定高氯酸溶液中氧化钬最小透过率波长的方法和程序。通过高精度分光光度计在200纳米至680纳米波长范围内对溶液的光谱透过率进行测量。该仪器的波长刻度精度通过对汞和氘发射线的大量测量得到验证。氧化钬溶液光谱透过率的测量是作为温度、纯度、浓度和光谱带宽的函数进行的。对与这些参数相关的不确定度以及与仪器波长刻度校准和数据分析相关的不确定度进行分析后，得出氧化钬溶液最小透过率波长测定的估计不确定度为±0.1纳米。
