摘要/Abstract

摘要： 本文系统地研究了灰化剂用量,pH,pAg对内敏直接正像乳剂灰化过程的影响。从研究中得到,随着灰化剂用量和pH的增加,直接正像乳剂的最大密度、最小密度和反差均增大,而感光度则降低。当pAg=7.3时,最大密度和反差均出现最大值,而感光度则随着pAg的增大而增大。

Abstract: In this paper, the influence of the amount of fogging agent, pH and pAg on the fogging process in direct positive emulsion was investigated. It was found that the D_max, D_min and gamma increase with increasing amount of fogging agent and pH, whereas the sensitivity of the emulsion decreases. The D_mix and gamma first increase with increasing pAg and then decrease. The maximum D_max appears at pAg=7.3. The sensitivity of the direct positive emulsion increases monotonically with increasing pAg.

Key words: direct positive emulsion, fogging process, fogging agent
