1·This article analyzes such Characteristics as sensitivity, fog density and contrast of the colour positive.

分析了彩色正片的感光度、灰雾度和灰差度等特性；

2·The method can smooth the fog density map and preserve large jumps along edges, which may make the estimated fog density map more accurately.

该方法既能平滑尘雾浓度图，又能很好地保留场景深度发生突变的边缘，使估计出的尘雾浓度图更加精确。

3·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。

4·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。

5·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。

6·The density and thick fog made the woods look like ghost while the street lights looked like moon with light circle.

浓密厚重的雾使树木看起来像鬼魂，街灯看起来像是带着柔光晕的月亮。
