沉积作用

As the years pass and layer on layer of rock fragments pile up, they are squeezed or compacted by the weight of the materials on top of them. Then sediment s may be cemented together, forming the sediment ary rocks.

随着时间的流逝，岩石和矿物碎屑一层层地堆积起来，上覆岩屑物质的重量对下伏岩屑产生压实作用，然后沉积物被胶结在一起，最终形成沉积岩。

This research reveals that dynamic action is the root reason for soil water-erosion, and that law of conservation of mass and energy is the basic principle of soil erosion, and that the coexistence of erosion and sediment is a universal rule of soilwater-erosion.

根据力学和物质与能量原理，对土壤水力侵蚀这一自然地理现象从哲学的高度进行分析，认为水动力作用是土壤水力侵蚀的根本原因；物质与能量守恒是土壤水力侵蚀的基本法则；侵蚀与沉积并存是土壤水力侵蚀的普遍规律。

They are sedimentary rocks, rocks which were laid down by the action of water on the bed of the ocean.

含有石油的岩石也与海洋有关，这是一种沉积岩，是在海水的作用下沉积到海底的。

They are sedimentary rocks, rocks which were laid down by the action of water on the bed of the ocean .

它们是沉积岩，是水作用于海床而沉积下来的。

In this tectonic setting, the special sedimentary environment and regional magmatism as well as tectonic force are the main factors which control the regional metallogenesis .

活动陆缘区特殊的沉积环境、区域岩浆活动及构造变形动力等作用，构成了区域矿产形成的主要背景和控制因素，从而使不同类型和元素组成的矿床得以形成，并表现区域成矿的总体分带规律。

The Raman spectra of the deposited species did not exhibit thespectral feature of buckminsterfullerene, but the hexagonal graphite and the amorphouscarbon in 〓 hybridization instead. The deposited species were desorbed and mass analyzed.

7经质量选择后的直链碳原子簇沉积在HOPG单晶面后改变了其本身的构型，主要以纯碳簇的形成存在，另外也发现相当一部分碳聚集而成芳香环，由于环状构型存在较多悬挂键，氢原子起到了饱和悬挂键的作用。

The results of simulations have shown that the molecular deposition film is similar to the self-assembled monolayer during scan process.

以量子化学计算结果作为初始条件，进行了分子沉积膜在金探针作用下的扫描过程和纳米压痕过程的模拟。

The results showed that the mixed surfactant had well distributed and uniform particles, and a size of 40-80μm. When the mass ratio of prepolymer and RDP was 1:1, the micro-capsule size was minimum, with little melamine resin deposited on the surface.

结果发现，复合型活性剂对微胶囊具有很好的分散作用，制备出的微胶囊颗粒均匀，粒径经检测在40~80μm；预聚体与RDP的质量比为1：1时，微胶囊的粒径最小，且只有少量蜜胺树脂沉积在微胶囊表面上。

When in the sedimentary formation these living thing chemical energy material, arrives between the earth's crust and the mantle rock magma region, because receives the high temperature high pressure the function, can the instantaneous aggravating internal heat response degree, also because these biological energy material stratum distributes non-uniform, thus has further created the partial region superheat, then intensified the profile conduction and the instantaneous paroxysm, finally intensified earth's surface and so on the earthquake volcano as well as plate movement terrain changes.

当沉积地层内的这些生物化学能物质，到达地壳与地幔之间的岩浆区域，由于受到高温高压的作用，就会瞬间加剧内热反应的程度，又由于这些生物能物质的地层分布不均匀，从而进一步造成了局部区域的过热，进而加剧了波形传导和瞬间爆发性，最终加剧了地震火山以及板块运动等地球表面的地形变化。

The intensity distribution of waves affecting on mudflats in Lianyungang, at conditions of tidal up-downs on water levels, is determined in this paper.
