1直接吸收光谱时分复用技术双线测温显示文摘水蒸气在7185.6 cm-1和6807.86 cm-1处的吸收线作为测温谱线对在1000~3000K的温度范围内都有较高的灵敏度和吸收线强。通过对1391 nm和1468 nm两个激光器采用时分复用的方式,可以实现上述两条H2O的吸收谱线的扫描。基于直接吸收光谱(DAS)技术,实现了对高温燃烧过程中温度和水蒸气浓度的非接触式测量。平焰炉的实验结果表明,DAS的测温结果与热电偶的结果相吻合,温度和浓度的不确定度分别为4.2%和8.7%。该方案可以用于温度跨度很大的燃烧场的诊断。李金义 杜振辉 2015激光杂志2015,36,8:4
2Electric dipole moment function and line intensities for the ground state of carbon monxide显示文摘An accurate electric dipole moment function(EDMF) is obtained for the carbon monoxide(CO) molecule(X1+Σ)by fitting the experimental rovibrational transitional moments. Additionally, an accurate ab initio EDMF is found using the highly accurate, multi-reference averaged coupled-pair functional(ACPF) approach with the basis set, aug-cc-p V6 Z, and a finite-field with ±0.005 a.u.(The unit a.u. is the abbreviation of atomic unit). This ab initio EDMF is very consistent with the fitted ones. The vibrational transition matrix moments and the Herman–Wallis factors, calculated with the Rydberg–Klein–Rees(RKR) potential and the fitted and ab initio EDMFs, are compared with experimental measurements. The consistency of these line intensities with the high-resolution transmission(HITRAN) molecular database demonstrates the improved accuracy of the fitted and ab initio EDMFs derived in this work.陈华君 吴杰 刘浩 程新路 2015Chinese Physics B2015,24,8:0
