Determination of bulk viscosity of liquid water via pulse duration measurements in stimulated Brillo
We present a method by which to determine the bulk viscosity of water from pulse duration measurements of stimulated Brillouin scattering (SBS). Beginning from a common model of Brillouin scattering, the bulk viscosity is shown to play an important role i
应用激光诱导荧光技术测量水中溶解有机物含量，具有检测速度快，灵敏度高等优点，而实际测量中荧光光谱受到激光发射光，瑞利散射和拉曼散射等因素的不同程度影响，难以建立荧光强度与有机物浓度的准确关系。在分析激光诱导荧光光谱特征的基础上,利用误差逆向传播(BP)神经网络对复杂非线性映射关系的强大逼近能力，对上述各影响因素进行综合处理，从而建立光谱的荧光强度与有机物浓度之间对应关系。通过对已知浓度有机物溶液的测量，用得到的荧光强度有机物浓度样本对BP神经网络进行精确训练，实现对水中溶解有机物浓度的测量。实验表明，以上
Equidistant combination wavelength screening and step-by-step phase-out method for the near-infrared
We applied near-infrared (NIR) spectroscopy with chemometrics for the rapid and reagent-free analysis of serum urea nitrogen (SUN). The modeling is based on the average effect of multiple sample partitions to achieve parameter selection with stability. A
利用直流稳定放电的Kr-U HCD灯作为放电等离子体源,在591.54 nm波长对U原子进行共振激发,在400～800nm波长范围内观察到了几百条激光敏化荧光光谱线,并由此测定了UHCD灯中相应能级集居数增量的分布。
The distributed acoustic sensing (DAS) has been extensively studied and widely used. A distributed acoustic sensing system based on the unbalanced Michelson interferometer with phase generated carrier (PGC) demodulation was designed and tested. The system
