1·The results indicate that using cement stabilized aeolian sand and macadam as base course for road is feasible.
试验结果表明，水泥稳定风积砂碎石做基层在公路上的应用是可行的。
2·Dune surface wind velocity distribution differences can lead to wind erosion and aeolian sand in different part of the dune.
沙丘表面风速分布的差异性是导致沙丘不同部位发生风蚀与风积的主要原因。
3·The density changes very little after soaking when the compactness of aeolian sand is above 90%.
风积沙的压实度达90%以上时，浸水所造成的密度改变很小。
4·In the paper, through the compaction test, the optimum moisture content and maximal dry density of aeolian sand are determined.
本文通过击实试验，确定了风积沙的最佳含水量和最大干密度。
1·Quartz grain surface textures in coastal dune sand which is mainly derived from beach sand have features characteristic of both typical aeolian environment and inheritable and reformable beach sand.
本文通过对广东和海南海岸沙丘砂石英颗粒的扫描电镜分析，认为其表面结构特征，既具有典型的风成环境特征。
2·The local aeolian geomorphic unit is chiefly some small-scale deflation shallow valley deflation relic hillock, dune and soil hillock etc. that generate facing wind slope on ridge-mound and in hollow.
当地的风成地貌主要是一些发育在垄岗的迎风波及洼地中的小型风蚀浅谷、风蚀残丘、沙丘、土豆等。
3·Types of lakes: tectonic lake, crater lake, fluvial lake, dammed lake, glacier lake, karst lake, Aeolian lake, impact crater lake and artificial lake.
湖泊分类：构造湖、火山口湖、冲积残留湖、堰塞湖、冰川湖、喀斯特湖、风成湖、陨石撞击湖和人工湖。
