砂质的

In this paper, mechanical properties of the sandy silt and fine sand mixed with cement and fly ashes in different amounts after different ages curing are researched, and the effect of cementing is compared. Through pull-out tests and direct shearing tests of geogrid in various soil, the interface characteristics of between geogrid and soil are measured.

本文通过室内物性试验、直剪试验和单轴压缩试验研究了采用不同掺量的水泥、粉煤灰加固后的砂质粉土和粉细砂养护不同龄期后的物理力学特性，并对加固效果进行了比较。

Within a prevailing dry, but sometimes with drywet alternated, closed intermountainal basin, the oil shale of Wulidui Formation, together with trona, salt, dolomite and silty mud rock, underwent a climatic variation circle from hothumid →dryheat→ intensively dryheat→dryheat→hothumid.

在干-湿交替但以干热为主的山间封闭盆地大背景下，五里堆组含油页岩岩系经历了"湿热作用较强→干热为主→高度干热→干热为主→湿热为主"的气候变化旋回，形成了油页岩、天然碱、盐岩、白云岩、粉砂质泥岩的不同韵律组合。

Sand has accumulated in a deltaic pattern on both the marine and lagoon sides of the inlets in conjunction with this diminishing current flow.

随着水流速度的减慢，砂质物遂以三角洲的形式堆积在进水道面向海洋和泻湖的两头。

Based on 76 sediments on 12 sandy beaches in July 2003 in South China （36 sublayer sediments included, but not analyzed in this paper）, granulometric characteristics are discussed.

根据2003年7月在华南沿海12个砂质海滩所取得的76个沉积物样品（其中次表层样品36个，不计入研究范围），就该区的沉积物粒度特征展开论述。

Its food mainly consisted of various smal l planktons and organical fragments and the animals had no obvious kind selectio n of food.

营埋栖生活，潜居砂质底，洞穴的深度与贝类长度相当，依靠水交换滤取食物，饵料以各种小型浮游生物及有机碎屑为主，对种类没有明显的选择性。

Fluvi tile sands deposited by delta distributaries are quartzose.

In order to investigate the compound constructed wetland role on the agricultural waster water purification, we built the biological filter with macrophyte of Zizania caduuciflora and bulrush, gravel and sand as their substrates.

研究了茭草、芦苇两种植物，砾石层、粗砂层、细砂层为基质的生物滤池和木炭吸附池构成的复合人工湿地装置净化溶岩地区农田排水中氨氮、总氮和总磷的去除效果。

Combined with sand-body distribution character, oil-bearing formation heterogeneity and oil water movement, strategy for increasing oil production has been put forward.

结合砂体的分布特征、储层非均质性、油水运动规律等资料的分析提出了挖潜增产措施。

The most important reason is the heavy heterogeneity of braided sandstones.

辫状河砂体的非均质性严重，这是影响开发效果的重要原因。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
