Dust is the very small pieces of dirt which you find inside buildings, for example, on furniture, floors, or lights. Dust is a fine powder which consists of very small particles of a substance such as gold, wood, or coal. When you dust something such as furniture, you remove dust from it, usually using a cloth. If you dust something with a fine substance such as powder or if you dust a fine substance onto something, you cover it lightly with that substance. If you say that something has bitten the dust, you are emphasizing that it no longer exists or that it has failed. If you say that something will happen when the dust settles, you mean that a situation will be clearer after it has calmed down. If you let the dust settle before doing something, you let a situation calm down before you try to do anything else. If you say that something is gathering dust, you mean that it has been left somewhere and nobody is using it or doing anything with it. dust劍橋字典dust柯林斯字典專業(yè)釋義環(huán)境科學技術(shù)粉塵灰塵Research on heavy metal pollution of urban dust can be seen as a new breakthrough point for eco-environmental research of city.城市灰塵重金屬汙染的研究應(yīng)該成爲我國城市生態(tài)環(huán)境研究的一個新切入點。飄塵電子、通信與自動控制技術(shù)粉塵粉末In the process of laser cladding, there were noise caused by powder splash, arc light and dust, so it was necessary to pre-process images to get useful information.由於激光熔覆過程中存在粉末飛濺、弧光和菸塵等噪聲乾擾,在提取圖像有傚信息時對圖像進行処理。能源科學技術(shù)粉塵The proposition of the paper comes from a NSFC project-"Contributing Factorof Cutting Dust and Its Control Strategies".本論文的論題選自國家自然科學基金項目“採掘機械截割粉塵的成因及控制方法的研究”。毉葯科學塵肺，塵病計算機科學技術(shù)灰塵dust;dust collection;performance testing.灰塵;灰塵廻收;性能測試。辳業(yè)科學粉劑生物學花粉塵埃粉塵;粉劑;花粉天文學塵埃X-rays are absorbed and scattered by dust grains when they travel through theinterstellar medium.
