We discuss and calibrate the spectronietry system based on concave reflection grating. The working principle, structure and parameters of the spectronietry system are introduced. For the wavelength calibration problem, three methods are put forward and discussed in detail with formulation calculation method, circular iteration method and interpolation. Interpolation is used to calibrate the concave reflection grating 相似文献

对产后1-6个月的乳母及其婴儿分别进行了乳汗中钙、铁、锌含量测定和婴儿身高、体重测量。结果显示,母乳中钙、铁含量与国内资料接近, 而锌含量偏低;乳汁中的铁和锌含量随喂养时间延长而逐渐下降;钙含量在四个月半前无明显变化,五个月后呈下降趋势。相关统计结果表明,乳汁中的钙、铁与婴儿的身高、体重无显著相关(P>0.05),锌与婴儿身高、体重呈显著正相关(P<0.01)。 相似文献

We discuss and calibrate the spectrometry system based on concave reflection grating. The working principle, structure and parameters of the spectrometry system are introduced. For the wavelength calibration problem, three methods are put forward and discussed in detail with formulation calculation method, circular iteration method and interpolation. Interpolation is used to calibrate the concave reflection grating spectrometry system and the error is less than 1 nm. Four spectrum images that the system collected are given in this paper. The experimental results indicate that a spectrometry system can be based on concave reflection grating and be calibrated by interpolation. 相似文献
