So the influence sand trap on the flow velocity can be ignored in the flow field.

结果表明,在实验过程中使用该集沙仪对流场中气流速度的影响很小,其测量结果具有较高的精确度和可靠性.

The distribution of ladybirds, green lacewings and spiders during cotton growth period was: the trap corn> the treatment cotton field> the contrast cotton field.

方法1986～2001年每月定期在住宅、稻田、旱地3种生境采用夹夜法调查，收集鼠类标本，分类鉴定，统计鼠密度和鼠种组成。

It is shown that trap generation is proportional to the time of field application, and increases exponentially with the field.

结果表明在一定时间下，介质中新陷阱密度的产生与强电场的指数关系成正比，而在一定强电场下与作用时间成正比。
