A preious population-based surey found a linear association between the number of lie births and chronic LBP, een after adjusting for age, BMI, smoking, and car ownership as an indicator of social class in both men and women. Also in pregnant women, the number of lie births was associated with LBP.

It is shown from the study results that when the CDOM concentration ρ≥62.5mg/L, there was only a peak in the EEMS spectrograms, the excitation and emission wavelengths moved blue with decreasing CDOM concentration, and the move in wavelength and the change in CDOM concentration were well correlated; when ρ≤52.5mg/L, there were 3 peaks in the EEMS spectrograms, and the EEMS spectral shapes were basically invariant when the CDOM concentration changed.

结果表明：当CDOM质量浓度ρ≥62.5mg/L时，其EEMS均为单一峰，随着质量浓度降低，激发和发射波长向短波长方向移动，这种波长移动变化与质量浓度的变化呈良好的线性相关关系；当ρ≤52.5mg/L时，其三维荧光光谱显示3个峰。质量浓度在此范围内变化时，EEMS谱形基本不变。
