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。
