求翻译：To reduce dust dispersion, pneumatic drills were equipped with air deflectors, flexible pipes directing the air out flow from the vacuum fan opening towards the ground . The air deflectors result in a driftreduction varying from 30% to 70%, but theresidual a.i. concentrations are too high to exclude the occurrence of sub-l是什么意思？ 待解决

为减少灰尘的分散、气动钻机配备有空气导流板、柔性管道引导空气流从真空风扇开口朝向地面。 空气导流板导致不同driftreduction从30%到70%,但theresidual临时代办浓度太高,不排除该事件的分致命影响的蜜蜂。

要减少尘土分散作用，气动排种式播种机装备以air deflectors，指挥空气flow从真空风扇开头的flexible管子往地面。 空气deflectors导致driftreduction变化从30%到70%的，但theresidual a.i。 集中太高以至于不能排除非杀生作用发生对蜂蜜蜂
