摘要/Abstract

摘要： 用超薄切片法及X-射线线扫描法研究了半个碘溴化银微晶中碘的成层分布,结果与预想的碘的分布相一致。横扫过薄样品的X-射线线扫描提供了一个比较准确的测定含有不同碘量成层结构的技术。这有助于我们改进碘溴化银乳剂的制备。文章还讨论了在该种工作条件下,X-射线源的空间分辨率和超薄切片的厚度。利用这种方法,把一种商用多层彩色片做超薄切片,用X-射线线扫描法直接对超薄切片中卤化银微晶的断面扫描,得到了各个轧剂层中的卤化银微晶的含碘结构。

Abstract: The Study of stratified iodide distribution in a single silver iodobromide tnicrocrystal by ultrathin sectioning and X-ray line scan were carried out. The result coincides with anticipated iodide distribution. X-ray line scan acrossthinner sample provides a relative accurate technique to determine stratified structure containing different amount of iodide. It will help us improve the preparation of silver iodobromide emulsion. The space resolving power of X-ray source and thickness of ultrathinsection in the experimental condition of this work were discussed.As a check test, the ultrathin section, of a commercial color film was prepared and the structure of microcrystals in the ultrathin section was determined by X-ray line scan.

Key words: ultrathin sectioning, X-ray line scan, stratified structure, iodide distribution, silver halide microcrystals
