If it is a pile of dirt, it must be laid upon.

如果它是一陀灰尘，我一定要躺在它上面。

I've got a speck of dust in my eye.

我眼睛里弄进了一粒灰尘。

There's not a speck of dust in their house.

他们的屋里没有一点儿灰尘。

Luminaire so constructed that dust of specified nature and fineness cannot enter it when it is used in a dust-laden atmosphere.

在灰尘较多的环境下，可以防止具有某些特定属性或特点的灰尘进入其中的灯具。

Feather dusters and dry rags pick up some of the dust they disturb, but most of it just settles elsewhere.

可以用鸡毛弹子和干抹布去清扫灰尘，但是大部分灰尘没有得到彻底的解决。

Found crystal collection on dust, not to use the feather brush, which may have to light soft, lint-free cloth breeze dust, do not force wipe off, so as to avoid frayed crystal.

发现灰尘，而不是水晶收集使用羽毛刷子，而要轻软，不掉毛的布风灰尘，不要用力擦掉，以免磨损水晶。

Before cleaning the floor, it would be better to remove dust by using vacuum cleaner with brush, so as to avoid tiny dust scratching the floor. After that, soak a towel in floor wax polish and wipe the floor. Do not pour wax polish directly onto the floor.

在清洁地板之前，最好用附上刷毛的吸尘机将地面灰尘清除，可避免灰尘在拭抹地板时刮伤地板表面，然后再用毛巾沾上适量的地板蜡水洗擦地板，切勿将蜡水直接倒在地板上洗擦。

From the above seems to show the failure, the author estimated that the fault is mostly the work of the subsidiary CRT circuit damage occurred because the cathode-ray tube voltage of the focus is very prone to failure similar to the above phenomenon, the phenomenon that gave rise to such failure is due mainly to display work over time, then the CRT focus very near the jack attached to a lot of dust very easily, which encountered wet dust easily lead to the air tubes of focus very significantly decrease the performance of socket contacts, then a cathode-ray tube focus to the natural voltage decline will be affected down, so that we could monitor the performance will be prone to poor focus, image display is a relatively vague.

从上面的显示故障现象来看，笔者估计该故障现象多半是显像管附属的工作电路发生了损坏，因为显像管的聚焦极电压十分容易发生类似上面的故障现象，引起这种故障现象的原因主要是显示器工作时间一长，那么显像管的聚焦极插孔附近很容易附着不少灰尘，这些灰尘遇到潮湿的空气后容易导致显像管的聚焦极插孔接触性能大大下降，那么一来显像管的聚焦极电压自然就会受到影响而下降下来，这样的话显示器也就容易出现聚焦性能不好、图象显示比较模糊的现象了。

More fine and lighter dust particles are fetched into the upper by the upper spiral airflow, forming strong spirally ash hoop at the inside of the top gap and bringing forth the accumulation of the dust particles, then are drawn forth from the upper entrance of special dust insulator, through the lower helical groove of dust insulator, tangential admission to the dust collector from the air return mouth of the dust collector's outside.

较细较轻的灰粒，由上旋涡气流带往上部，在顶盖下面形成强烈旋转的灰环，产生灰粒的集聚，并被从特设的灰尘隔离室上部洞口引出，经过灰尘隔离室的下部螺旋槽，从除尘器外壁回风口切向引入除尘器，筒体下部与内部气流汇合，灰粒被分离而落入灰斗。

It covered the city with ashes,puffed out over the river and valleys,and hooked to the trees in the forest in thick tuffs.

这让整座城市都覆盖上了灰尘，灰尘被吹散到河流和山谷，厚厚地附着在森林里的树上。
