文章就电泳图谱的种类、胶片的选择、滤色镜的使用 ,怎样选择正确曝光时间以及相机镜头、光源设备的配置、使用做了介绍 ,并针对用考马亮兰染色的电泳图谱存在着反差较低的问题 ,叙述了从电泳图谱拍摄的开始到最后的冲洗胶片以及放大相片的全过程要始终围绕提高反差这一关键问题的方法。
2) high contrast
高反差
1.

2.
In association with the sensitometric results obtained on using developers containing different inhibitors, it is concluded that high contrast caused by inhibitors can be achieved when the inhibitor moderately adsorbs on the latent image, coupled with a weak adsorption on silver bromide.
本文利用吸附曲线及电化学的方法,研究了一系列抑制剂在银及溴化银上的吸附行为,将这些吸附性质与显影过程中相应的抑制剂存在时的显影结果对比,实验表明:只有当抑制剂在银上为中等的吸附,而在溴化银上吸附很小时,才可能利用抑制剂达到高反差。

补充资料：反差增强
又称对比度增强，是一种点处理方法，通过对像元亮度值（又称灰度级或灰度值）的变换来实现。是图像增强的常用方法之一
