您要查找的是不是：
- The resource of sand and dust particles has little influence on the CCN concentrations. 层状云中 CCN浓度随高度变化不大
- The air is filtered from dirt and dust particles. 空气中的污物和灰尘颗粒都被过滤掉了。
- sand and dust particles 沙尘颗粒
- The water vapor and dust particles also serve to reflect the rays of the sun. 水蒸气及灰尘微粒也起到反射太阳光的作用。
- The fragile land quickly lost its topsoil and became nothing but sand and dust. 那单薄的土地很快就失去了表土，成为沙粒和尘埃。
- The ring itself is tenuous, made up of a thin array of ice and dust particles. 新光环是由非常稀疏的冰粒和尘埃粒子组成的。
- A dry wind called the Harmattan, which blows from the Sahara desert over Ghana and Nigeria, carries much sand and dust. 一种叫“哈马顿”的干燥的风自撒哈拉大沙漠夹带着大量的沙粒和尘埃，越过加纳和尼日利亚。
- The wind causes much wearing of rocks,particularly if sand and dust are blown along by it. 风引起岩石磨耗，尤其是当风沙很大时。
- A whirlwind is small in size and may suck up sand and dust as it moves over the surface of the Earth. 旋风的范围小，当它在地球表面移过时，可以吸进沙和灰尘。
- The wind causes much wearing of rocks, particularly if sand and dust are blown along by it. 风引起岩石磨耗，尤其是当风沙很大时。
- Corrosion is aggravated locally by pollutants deriving from the operation of a plant (for example acids, alkalis or salts, organic solvents, aggressive gases and dust particles). 工厂里出来的污染物使腐蚀局部恶化（如：酸，碱或盐，有机溶剂，侵略性气体和尘粒。）
- Desert (2nd volume): remote and vast melody describing sand and dust floated by a stiff wind implying the sense of loneliness and immenseness. 沙漠(第二段)：悠远壮阔的曲风,描述著沙漠中,一阵狂风吹起了黄沙纷飞，增添寂寥与壮阔的感觉。
- Abstract: Sand and dust are both products of physical weathering.However,their behaviors are entirely different in the eolian transport process. 摘 要： 沙与尘虽然都是岩石物理风化的产物，但在风力作用下，习性截然不同。
- Sand and dust are both products of physical weathering.However, their behaviors are entirely different in the eolian transport process. 摘要沙与尘虽然都是岩石物理风化的产物，但在风力作用下，习性截然不同。
- For example, it says climate change and land use are expected to increase desertification worldwide, increasing the risk of sand and dust storms. 例如，气候变化和土地的开发使用预计将加剧世界范围的沙漠化，增加沙尘暴的风险。
- Moreover, with the fast improvement of citified level and fast development of traffic and civil aviation, the loss made by the same sand and dust weather largely increased. 而沙尘暴监测与预警技术的研究在防灾和减灾中就显得尤为紧迫和重要。
- We can see the dust particles floating in the sunlight clearly. 我们可以很清楚地看到阳光下的灰尘颗粒。
- Sand and leaves trapped the water in the stream. 沙子和树叶堵住了小河的水流。
- The bottom layer is a mixture of sand and clay. 最下面的一层是沙和泥的混合物。
