Shanlinsi Forest Recreational Park is located more than 2000 meters above sea level. Looking over the forest, it is full of towering cedars and cypresses with a natural and primitive breath of air. In this vast forest area, there is a well-known pristine eco-forest and dead cryptomeria trees standing tall in the swamp. Such desolate beauty makes people feel really lonely.

海拔超过二千公尺的杉林溪，放眼过去尽是高耸的杉树、桧木林，有著自然而原始的气息，而在这片面积广大的森林中，有一片鲜为人知的原始生态林、一片因为九二一阻塞河道形成的沼泽地，一棵棵死亡的柳杉笔直的朝向蓝天，有种孤寂、苍凉的美感。

Lithic associations composed chiefly of quartzose sandstones were developed in delta plains and delta distributary channels with good physical properties to provide available reservoir space.

以石英砂岩为主的岩性组合主要形成于三角洲平原及三角洲前缘分流河道，物性好，提供了良好的储集空间。

Ice dam, ice cover and ice jam, which are formed by stack, jammed and collective ice, can increase river resistance and water stage, resulting in flood, construction damage and navigation problems.

冰块堆积，堵塞和聚集形成的冰坝、冰盖和冰塞会导致河道阻力增加，致使上游水位上涨，并可能造成冰期洪水，建筑物破坏，航运不畅等危害。

Controlled by north and west depositional system, Fu-Yang oil-bearing layer consists of delta distributary plain and delta front sub-facies depsits of delta depositonal system, widely distributed various distributary channel sand deposits come into being favorable reservoir space.

目的层段扶杨油层沉积时期处于松辽盆地坳陷期的加速沉降阶段，受控于北部和西部沉积体系韵扶杨油层处于三角洲分流平原及三角洲前缘亚相，沉积的各种河道砂体平面上错迭连片，为扶杨油层形成大面积岩性油藏提供了良好的储集空间。

Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.

研究结果显示，两孔记录的古气候波动可与深海氧同位素曲线进行对比：对应于深海氧同位素曲线第6阶段(MIS6)，堆积厚层的河道相粗颗粒沉积及第3硬土层，反映当时气候寒冷；第5阶段(MIS5)，为滨海湖沼沉积，沉积物的颗粒显著变细；第4阶段(MIS4)，本区形成第2硬土层；第3阶段(MIS3)的早期，本区也发育滨海湖沼沉积，中晚期则形成潟湖—砂坝体系，在滨海平原区普遍发育粉、细砂层；第2阶段(MIS2)，地层由下粗上细的沉积序列构成，下部为黄灰、棕黄色粉砂，上部则为棕黄色或暗绿色硬粘土。

Through analysis on landscape water pattern, quality character and affinitive degree closing to people, this article does some research on water quality control technology application for river and man-made closed landscape water in Shanghai 2010 Expo site. The research results forms technology integration and provides some technical support to express the theme "better city, better life and beautiful water, beautiful city".

通过分析2010年上海世博会园区景观水体形式、水质特性以及与人体接触的密切程度，研究相应的水质控制技术在世博园区景观河道和人工景观水体中的应用，形成世博园区营造舒适水环境的水质控制技术集成，为体现&城市让生活更美好&的世博会主题提供技术保障。

Research has indicated that the advantaged sedimentary facies, sand structure granularity and chipping component are the important factors affected the physical property of the reservoir; the connexity of many phases distributary riverway sand in side direction has offered the condition formed the distributing stabilization in landscape orientation and biggish scale gas reservoir; early i...

认为有利的沉积相带、砂岩结构粒度、碎屑组分是影响储集体物性的重要因素；多期分流河道砂体在侧向上相互连通为形成横向上分布稳定、规模较大的工业气藏提供了条件；烃类的早期侵位有利于储层原生孔隙的保存和次生孔隙的形成，对高效储集体的形成有着重要作用。

It indicates that crevasse channel is a kind of very narrow and shallow short range small channel with a fixed path which is formed among wide-ranged channels by the major channel after the avulsion crevasse in a fluvial and deltic sedimentary system.

指出决口水道是在河流及三角洲沉积体系中，由主河道于大洪水期冲裂决口后，在广阔河道间形成的具有固定路径及一定限流作用的极窄、浅的短程小型水道。

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。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
