1·Because they are porous, sedimentary rocks, such as sandstones and conglomerates, are important potential sources of groundwater.

由于像如砂岩和砾岩这样的沉积岩是多孔的，它们是地下水的重要潜在来源。

2·Although most fossils are found in marine sedimentary rocks, they also are found in terrestrial deposits left by streams and lakes.

虽然大多数化石是在海洋沉积岩中发现的，但它们也存在于河流和湖泊所留下的陆地沉积物中。

3·In this process, sedimentary rocks that originally formed on the seabed may be folded upwards to altitudes of more than 26,000 feet.

在这个过程中，最初形成于海床上的沉积岩可能会向上折叠到26000英尺以上的高度。

4·Attempts were made to calculate Earth's age from the thickness of surviving sedimentary rock and from the current level of the oceans' salinity.

人们曾试图根据现存沉积岩的厚度和目前海洋的盐度水平来计算地球的年龄。

5·It is a global record: there is remarkably little variation in isotope ratios in sedimentary specimens taken from different continental locations.

这是一个全球性的记录：在取自不同大陆位置的沉积标本中，同位素比率的变化非常小。

6·Because of these advantages, sedimentary evidence can be dated with sufficient accuracy by radiometric methods to establish a precise chronology of the ice ages.

由于这些优点，可以通过辐射测量方法以足够确定沉积证据的年代，从而建立一个精确的冰河时代年表。

7·Sedimentary rocks—the most common rock type near the surface—are also the most common reservoirs for water because they contain the most space that can be filled with water.

沉积岩——地表附近最常见的岩石类型——也是最常见的储水层，因为它们可以装水的空间最多。

8·The sedimentary systems were divided according to the characteristics in rock types, color and authigene.

根据岩石类型、颜色、自生矿物等特征，对沉积体系进行划分。

9·The sedimentary rocks are graywacke, siltstone, tuff andpellitie, etc.

沉积岩有杂砂岩、粉砂岩、凝灰岩、泥质岩等。

10·Concepts of sedimentary rock.

沉积岩的一般概念。

沉淀的

1·A sedimentary material consisting of very fine particles intermediate in size between sand and clay.

泥沙，淤泥由大小介于沙和泥之间的非常细小的微粒构成的沉淀性物质。

2·I am merely going to take a sedimentary section from this well, and segregate the sediment in the lab.

我不过是想从这口井里提取一些沉淀部分，然后在实验室里分离出来。

3·In the present situation of China, the root of many social problems is the excessively large amount of sedimentary money and its amazingly fast swelling.

沉淀资金过大、膨胀速度过快是现阶段我国经济诸多问题的根源。

4·Coal is a sedimentary rock composed principally of organic carbonaceous macerals and inorganic minerals.

煤是一种有机沉淀岩，主要包括有机碳化合物和无机矿物。

沉降的

1·The principle of improved method for calculating particle size tested by light transmission is to use the inherent sedimentary height of the same kind of powder with various sizes.

经改进的光透法测试粉末粒度计算方法的原理是：同种粉末各不同粒径颗粒在特定的条件下有它固定的沉降高度。

2·A process was designed which used quick lime as capture reagent of the dust and SO2, cyclone separator and sedimentary chamber as separation equipment.

设计了一种以生石灰为粉尘的捕获剂和SO2的净化剂，以旋风除尘器与沉降室为粉尘分离设备的工艺流程。

3·Aimed at the experimentation flux of silt Disc separator, the principle of Disc separator was introduced and the conditions under which sedimentary granules would not be taken by liquid were analyzed.

针对黄河泥沙碟式分离机试验流量，介绍了碟式分离机工作原理，分析了沉降颗粒不被液流带走的条件。
