模糊、淡化的黑白照片显现加固研究

本文研究了早期黑白照片模糊、淡化的原因,首次提出了在影像层中形成的空气、空隙-粒子、间隔散射界面是造成黑白照片模糊、淡化现象的主要原因。并且研制出了消除该散射界面、使模糊、淡化的黑白照片显现出原貌的显现加固剂。通过扫描电镜和相关性质实验测试,说明该保护剂具有良好的显色功能和防霉、抗水、抗粘结性等功能。

In this paper, as to the fussy and dilution of white ＆ black photograph,we firstly show that air-particle scatting interface is the key factor. Accordingly one kind of cryoprotector is researched to eliminate the scatting interface, thus the photos are consolidated. And the results of scanning electron microscope and the other experiment tests demonstrate that the cryoprotector has several effects： revivificai tion, mould - resistance, water - resistance, cohered- resistance, etc.
