徐州市作为长江三角洲的"半日交通圈，"直接承纳了《长江三角洲地区现代化公路水路交通规划纲要》所带来的有关惠利，对于其发展区域经济有着十分深刻的影响作用。

For the entire subaqueous delta, accurate calculations for the critical value will depend upon a sound understanding of the sediment retention of the deltaic system. Moreover, it would be appropriate to consider two critical discharges, one for the maintenance of the delta volume, and the other for the maintenance of the surface area of the delta on land.

对于水下三角洲整体而言，应根据沉积物滞留指数来更准确地估算临界输沙率，而且需要区分2个&临界输沙率&，一个是保持三角洲体积的临界值，另一个是保持三角洲陆上部分面积的临界值。

In late September and early October 2002, 163 surface samples were grabbed from the Yangtze subaqueous delta within a range of 122°~123°E and 30°50'~31°50'N. Based on analyses of grain size, foraminifera, ostracoda, carbonate, organic carbon of surface sediments, the study area can be divided into two parts, i.

2002年9-10月在长江水下三角洲获取了163个表层样，综合粒度、有孔虫、介形类、有机碳以及CaCO3含量的资料表明，研究区明显分为两部分，即长江河口现代三角洲和晚更新世末期三角洲。

The medium-grained sandstones and medium-fine-grained sandstones form good reservoirs and the poststones medium reservoirs, while siltstones form poor reservoirs and pelitic siltstones poorest reservoirs. Sand bodies mostly develop in sand-flats, tidal channels and distributary channels of braided stream delta microfacies. The reservoir rocks of sand-flat and tidal channel are best with the physical property. Diagenesis such as compaction, cementation and dissolution has strongly reformed the reservoir rocks and the late dissolution has greatly improved their porosity and permeability.

中粒砂岩、中细粒砂岩属好储层，细粒砂岩属中等储层，粉细砂岩，粉砂岩属较差储层，而泥质粉砂岩则属差储层；砂坪、潮道和辫状河三角洲分流河道微相中的砂体最发育，它们决定了储集岩的发育、分布及原始物性条件；砂坪和潮道储集岩的物性最好，辫状河三角洲分流河道储集岩的物性次之，砂泥混合坪、辫状河三角洲分流河道间储集岩的物性较差；成岩作用对本区CⅠ油组的储层有强烈的改造作用，尤其是较晚期的溶蚀作用对岩石的储集性能有明显的改善，对本区CⅠ油组中孔高渗透储层的形成有很大的贡献。

It is found that the west slope in the Eastern Sag has the formation condition of braided river delta, the development area and stratigraphic position of braided river delta sedimentary system are defined, and the subfacies and microfacies are identified.

确定东部凹陷西部斜坡带具备辫状河三角洲的形成条件，并确定了辫状河三角洲沉积体系发育范围和层位，识别了辫状河三角洲沉积亚相及微相。

In the basis of the facies markers and facies analysis of principle, there are mainly river、delta and lake depositional sysytems in Upper Triassic of Nanniwan field,in which all kinds of difference sedimentary subfacies and sedimentary microfacies are distinguished, such as meandering river、delta plain、delta front、submerged distributary river course、frontal sheet sand and so on.

利用收集到的各种相标志和相分析原则，对研究区的沉积相进行了比较细致的研究，将南泥湾探区上三叠统分为河流、三角洲、湖泊三种沉积体系，并在各沉积体系中细划出曲流河、三角洲平原、三角洲前缘、浅湖等沉积亚相和水下分流河道、河口坝、前缘席状砂等沉积微相。

We have taked sedimentary facies research on the second member of Shanxi formation of Changbei gas field, this area pertained to marine facies braid river delta sedimentary system, we have gived a detailed discriiption on different subfacies, microfacies, sandbody's sedimentary character and distribution for the braid river delta sedimentary system.

对长北气田山2段开展了精细沉积相研究，确定该地区山2段属于海相辫状河三角洲沉积体系，并对该三角洲沉积体系的各亚相、微相和砂体展布特征与演化规律进行了详细研究，建立了自北向南延伸的辫状河三角洲沉积模式。2。

There are many academic fruits of the development of the City Clusters on Yangtze River Delta. It is few productions in studying the development of Nanjing's satellite cities as the system of "zonary cities". In 2004, the cities' governments of the City Clusters on Yangtze River Delta had extended the boundary of developing stratagems to extensive Yangtze River Delta.

对长江三角洲城市群发展研究的学术成果很多，但把南京市卫星城市发展以&带城&为体系来研究则没有见到。2004 年，长江三角洲城市群的城市政府已经把发展战略的边界延伸到&泛长江三角洲&。

The main target zone of the CARACOLES area in eastern Venezuela basin is a series of delta facies sedimentation in ocean-land transitional environment.

东委内瑞拉盆地卡拉高莱斯地区主要目的层为一套海陆过渡环境的三角洲相沉积，三角洲平原河道、三角洲前缘水下分流河道、河口坝及决口扇构成区内主要沉积骨架砂体，各种微相砂体单层厚度薄，分布面积小，在地震剖面上无法直接识别。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
