富氯乳剂的增感技术

从硫－金增感的机理入手，讨论了化学增感过程。针对氯化银增感的同时灰雾也急剧上升这一弊端，提出了硫－金混合增感、硫增感两步到位，以及化学、光谱增感交叉进行等一系列增感的方法。

光谱增感AgBrI-T颗粒乳剂光电子特性

用微波吸收相敏技术检测了光谱增感AgBrI T颗粒乳剂的自由光电子时间分辨谱 ,观察到增感样品在染料增感吸收峰位置有明显的光电子信号 ,在AgBrI T颗粒固有吸收带自由光电子衰减时间比未增感样品的衰减时间短。

光谱增感染料分散方法的改进及应用

对黑白、彩色相纸所用光谱增感染料在水溶液中的的分散工艺进行改进,成功地去除有机溶剂甲醇的使用,使增感染料稳定的分散在水溶液当中;将该水溶液应用于黑白、彩色感光材料的乳剂中,增感后的乳剂照相性能均达到醇溶液制备水平,在消除有机溶剂对工人健康的危害和对环境的污染的同时,还可降低生产成本。

Photogrammetry - Remote Sensing on the Study of Monuments and Historical Centers： The Effect of Hazards -The Case of Delphi Historical Center

Monuments and historical centers, because of their particular importance, are studied in multiple ways. The study concerns different scientific disciplines and technology. Photogrammetry and remote sensing contribute essentially to this study, because of the valuable qualitative and quantitative information they offer. In this paper we search through the possibilities of very high resolution satellite imagery on historical centers study, referring to Delphi historical center. The study concerns image enhancement techniques and visual interpretation of Ikonos satellite imagery. Image enhancement techniques facilitate visual interpretation, detection and recognition, of the physiognomy and spatial arrangement of Delphi historical center and offer information about physical and architectural features in the wide area of the historical center.
