Based on the characters of water erosion and rock clasts , the zhangxia loess is possibly a product of aeolian - talus - pluvial process 张夏黄土下部呈现明显的水流侵蚀痕迹，中间夹有围岩碎屑，应属于风成、坡积、洪积成因的黄土状土。
Loess is silt - sized aeolian deposit and is mainly composed of quartz and feldspars , its osl signals can be set to zero by exposure to light 黄土作为一种风积物，主要矿物是长石和石英，光释光信号在搬运漂浮于空中时可以被阳光曝晒“回零” 。
The aeolian sand is the most abundant material in the desert area , but its engineering property is so bad that it has not been used widely as paving material 风积沙是沙漠地区最为丰富的物质，由于其工程性质较差，目前仍未被广泛用作沙漠地区公路的铺筑材料。
Through field test and observation , we have achieved the desired results and proved that the using of aeolian sand as paving material is feasible further 同时，本课题铺筑了1公里长的试验路，通过现场检测和观察，进一步验证了风积沙用作沙漠公路路面材料的可靠性。
Under the same soil moisture suction , water holding quantity in soils from high to low in turn was lou soil , hei - lu soil , loessial soil and aeolian - sandy soil 土壤水分动态变化过程(干湿交替次数)和变化强度(温度变化)对黄土高原地区四种土壤钾的有效性有较大影响。
On the basis of research of various physical characteristics of coal gangue , fly ash , aeolian sand , through contrast experiment , we chose this new reinforce material 在对煤矸石、粉煤灰和风积砂土的各项物理力学特性进行试验研究的基础上，通过对比试验选择了可供工程应用的新型固化剂。
Every children can do some new toys ? a slender necklace made by popcorn , manual small ornament and germanize aeolian bells made by wallpaper . we hang the bells from the ceiling 每天孩子们都会做点儿新玩意- -爆米花串成的细链子、手工做的小装饰品和墙纸样做的德国式风铃，我们把这些风铃挂在了天花板上。
The holocene loess - soil sequence in the loess plateau constitutes an excellent record of evolution of soil formation , monsoonal climate , aeolian dust accumulation and influences of arable farming of over 8000 years 长期农牧业的发展，使得天然植被在大多数地方已荡然无存，大片的林地被开垦为农田或被开辟为城市用地。
The ongoing fluvial , marine and aeolian processes in the site have produced a variety of landforms , including coral reefs , long sandy beaches , coastal dunes , lake systems , swamps , and extensive reed and papyrus wetlands 不断的河流，海洋和风的侵蚀作用使得该地呈现多样地貌，包括珊瑚礁、漫长的沙滩、海岸沙丘、湖泊、沼泽、大片的芦苇丛和纸草沼泽。
The slity soil has the greatest frost heave strength in all of soil and the aerolian sandy soil belongs to it , so it is necessary to the study on frost heave mechanics of aeolian sandy soil and measure of prevent frost heave in railway construction 风积砂土属于粉质土，而粉质土的冻胀强度是最大的，因而对风积砂土的冻胀性及其对铁路危害的研究是非常有必要的。
