砂质

A sandy loam with a clay subsoil is best.

砂质壤土与粘土地基是最好的。

The feature of earth chemistry of volcanic rock in Xiangshan Group reflects that it belongs to the series of oceanic tholeiite in oceanic spreading tectonic environment.

结果 香山群的时代划归为中晚寒武世较合适；香山群主体是一套由板岩、细、粉砂岩和砂岩组成的浊积岩系，其砂岩类型主要是长石石英砂岩、细粒石英砂岩和粉砂质石英砂岩，前寒武纪变沉积岩和花岗片麻岩为主要碎屑来源和物源区组成；砂岩的岩石地球化学特征指示香山群属发育在被动大陆边缘斜坡环境中的沉积物，火山岩岩石地球化学特征反映其应属大洋扩张构造环境下的大洋拉斑玄武岩系列。

Many sparsely disseminated and nodular pyrite can be found in the oil shales. With the oil shale occurring in the bottom, trona, salt, dolomite and silty mud rock also the oil shale make up many sedimentary rhythms.

其内可见大量星点状、结核状黄铁矿，并作为天然碱矿层的直接底板与天然碱、盐岩、白云岩及粉砂质泥岩构成了多个韵律旋回。

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。

There is sufficient sand available to blanket the unconformity.

这里有充足的砂质物铺盖不整合面。

There is sufficien t sand available to blanket the unconformity.

这里有充足的砂质物铺盖不整合面。

The soils are derived from volcanic ash and consist of sandy to sandy-loam earth.

这里的土壤来源于火山灰和砂质壤土。

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。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

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。

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。
