fine sand细沙〔砂〕
sand dune An accumulation of loose sand heaped up by the wind, commonly found along low-lying seashores above high-tide level, more rarely on the border of large lakes or river valleys, as well as in various desert regions, where there is abundant dry surface sand during some part of the year沙丘 (被风堆积的松散的沙的沉积,常在有很高的潮水和地势低洼的海边,很少在大湖边或河流边。同样也在很多沙漠地区,那里有很多多年积累在地表的沙。)
sand dune fixation Stabilization of dunes effected by the planting of marram grass (Ammophila arenaria), or rice grass, whose long roots bind the surface layers of sand and so hinder its removal by wind. A larger scale method of dealing with the same problem is by afforestation沙丘固定 (通过种植滨草(砂滨草蚤缀属)或稻草稳定沙丘,这些草长长的根可以绑住沙的表面因此可以阻止沙被风吹动。更大规模的处理同样问题的方法是造林。)
sand extraction The extraction of sand by mining for building purposes and for the extraction of heavy minerals such as rutile and zircon沙石开采 (为了建筑使用的矿物和获得重金属例如金红石和锆石而开采沙子。)
sand flat A sandy tidal flat barren of vegetation. A tidal flat is an extensive, nearly horizontal, marshy or barren tract of land that is alternately covered and uncovered by the tide, and consisting of unconsolidated sediment (mostly mud and sand). It may form the top surface of a deltaic deposit沙坪 (没有植物的沙的潮汐滩地。潮汐滩地广阔的、几乎水平的、沼泽或贫瘠的土地,它间歇的被潮汐覆盖,由疏松的沉积物组成(主要是泥土和沙)。它可以构成三角洲沉积的表面。)
sand pit A place where sand is extracted from the ground砂坑 (在地面开采砂的位置。)
sand pit磨光玻璃表面上的小凹坑
sand trap除砂盘
tar sand A sandstone in which hydrocarbons have been trapped; the lighter compounds evaporate, leaving a residue of asphalt in the rock pores沥青砂 (一种砂岩,其中的碳氢化合物已被分离,蒸发较轻的化合物,留在岩石孔隙的沥青残渣。)
