利用电泳光散射法可以确定带电颗粒的电泳迁移率,由电泳迁移率计算颗粒的Zeta电位需要准确确定Henry函数的数值。为此,利用最小二乘算法对精确Henry函数值进行拟合,获得优化Henry函数表达式;基于Gouy-chapman-Stern双电层模型理论,求解不同浓度、不同类型电解质溶液中颗粒的双电层厚度,从而获得准确的颗粒半径a与双电层厚度k-1的比值ka;最后利用优化的函数表达式获得准确的Henry函数值。使用该方法分别计算4种不同浓度电解质下颗粒的Zeta电位,实验结果表明,利用优化的Henry函数可以有效提高颗粒Zeta电位的计算精度,计算结果的相对误差小于1.0%。

使用动态光散射法可以获得颗粒的光强加权平均粒径,以及光强加权颗粒粒度分布。为获得数量或体积加权颗粒粒度分布,提出从光强分布到数量分布转换的直接比值法。该方法首先依据Mie散射理论求解不同粒径颗粒的散射光强,然后将光强分布与对应颗粒的散射光强进行比对,获得颗粒的数量分布,进而得到颗粒的体积分布。使用动态光散射法测量得到聚苯乙烯乳胶球混合样品的光强分布,利用直接比值法将光强分布转换为数量分布和体积分布,并与扫描电子显微镜测量的数量分布进行了对比,实验数据表明采用直接比值法能够获得准确的数量分布。

A ten-month field research study was meticulously conducted at Robert Moses State Park (RMSP) on the south shore of Long Island, NY. The objective was to determine if aerial phenomena of an unknown nature exist over a coastal location and to characterize their properties and behaviors. Primary and secondary field observation methods were utilized in this data-centric study. Forensic engineering principles and methodologies guided the study. The challenges set forward were object detection, observation, and characterization, where multispectral electro-optical devices and radar were employed due to limited visual acuity and intermittent presentation of the phenomena. The primary means of detection utilized a 3 cm X-band radar operating in two scan geometries, the X- and Y-axis. Multispectral electro-optical devices were utilized as a secondary means of detection and identification. Data was emphasized using HF and LF detectors and spectrum analyzers incorporating EM, ultrasonic, magnetic, and RF field transducers to record spectral data in these domains. Data collection concentrated on characterizing VIS, NIR, SWIR, LWIR, UVA, UVB, UVc, and the higher energy spectral range of ionizing radiation (alpha, beta, gamma, and X-ray) recorded by Geiger-Müller counters as well as special purpose semiconductor diode sensors.
