density fog

It yields a long density range, and its development latitude allows push processing with relatively low fog.

它将产生高密度变化范围，同时显影过程允许进行会造成相关联的低灰雾的迫冲。

Methods 1%yekang cockroach gel bait and 0.5% Permanone smoke fog were used for chemical control. Adhesive killing method was applied in density investigation.

方法采用1%晔康杀蟑胶饵和0.5%氯菊酯的烟雾剂，密度监测采用粘捕法。

Chemical fog: Overall density produced by an excessive degree of development, due to unexposed silver halides being attacked by the developing solution.

化学灰雾：显影过度造成全面性增加的密度。是由于未曝光的卤化银被显影液感染所引致。
