摘要/Abstract

摘要： 本文测定了银盐扩散转移过程正负影像的覆盖力,测定结果表明,正像比负像覆盖力大3—10倍。这正是扩散转移体系的特点之一。覆盖力在很大程度上依赖于密度,随着密度的增大,覆盖力以指数形式下降。改变正像接受层的物理显影核或核的载体,都会引起覆盖力的变化。同时,沉积的银颗粒越细,覆盖力也越大。

Abstract: In this paper the covering power of the positive and negative images was determined. It was found that the covering power of the positive image is 3-10 times higher than that of the negative. It was found that the more the silver deposited, the lower the covering power will be on the same positive. And the covering power is seen to depend greatly on the density. With increasing density, the covering power diminishes exponentially. The experimental results showed that any change of the physical development nuclei or nuclei carriers (different kinds of hydrophilic silica) in the positive receiving layer will affect the covering power of the final image, and that the smaller the particle size of deposited silver, the higher the covering power.
