Some authors report that collagen in derma after industrial treating by the salts of chrom imply rather diffuse X-ray patterns. At the same time our X-ray photographs of these samples using Cr Ka-irradiation rather then Cu Ka-irradiation are all of fine quality. Therefore the collagen in derma is not distroed after salt treatment. In fact Ka-seria of Cu (using in all other investigations) cause transitions in Cr-atoms implying as diffuse phone on the film.
一些作者报告称，经铬盐工业处理后的真皮中的胶原蛋白呈现出相当弥散的X射线图谱。与此同时，我们使用Cr Kα辐射而非Cu Kα辐射对这些样品拍摄的X射线照片质量都很好。因此，盐处理后真皮中的胶原蛋白并未受到破坏。实际上，Cu的Kα系列（在所有其他研究中使用）会导致Cr原子发生跃迁，在胶片上表现为弥散光斑。
