Carpets or rugsmats may be vacuumed using a cleaner that does not throw dust into the air or steam cleaned if soiled with body fluids 地毡及垫子可以不散发尘粒的吸尘机清洁。如地毡及垫子被体液弄污,则以蒸气清洁。

After months of delays we are finally ready to begin our search for interstellar particles of dust trapped in the aerogel collector from nasa ' s stardust mission 在数个月的延迟后我们终于准备好开始搜寻气凝胶中的尘粒了!
A mote stuck to a tree trunk often cannot communicate directly with a neighbor on the other side of the trunk just a meter or two away 因此固定在树干上的尘粒,经常无法直接与一、两公尺之外、位于树干另一侧的尘粒交换讯号。
Life - bearing meteoroids and dust particles would be exposed to the vacuum of space , extremes in temperature and several different kinds of radiation 带有生命的流星体与尘粒,还会暴露在宇宙的真空、极端的温度与数种不同的辐射之下。
But unlike pdas , motes can join forces in ad hoc networks to form a system that has greater computational power than its parts 不过,尘粒有一点与pda不同,它们可透过特定网络结合彼此的力量,形成单一系统,取得比个别零件大的运算能力。
Through analyzing the movement of a single particle in gas , it is pointed out that the effective method to control blasting - dust is to enlarge the particle - size 摘要通过对气流中单个尘粒的运动分析,指出降低爆尘的有效方法是增大粒径。
Dust indicates dry weather and since most weather changes come from the west , a red sky at night usually indicates dry weather approaching 尘粒多意味着天气干燥,因为大部分天气是由西向东发生的,晚上天空发红代表着干燥的天气系统正在靠近。
Cleans thoroughly between the fibre of carpets , lifts out ground - in dirt and traps in the crystalline powder . simply vacuum away when dry 能深入地毡纤维间,将隐蔽底层的污垢尘粒锁紧,变成结晶状粉末推出,只需以吸尘机将粉末吸走便可,轻松便捷。
That is why motes spend about 99 percent of their lives “ sleeping ” in a standby mode that drops the power consumption to a few millionths of a watt 因此,尘粒99 %的生命必须处于睡眠状况,也就是待机模式,才能把耗电率压低到百万分之几瓦特。
