本文通过解放后黄河口三次改道，河口延伸和摆动的实测资料，探讨科氏力对塑造黄河三角洲发育模式的影响，以便预估每条流路河口归槽后的摆动走向。

Delta plain divided distributary river course and between river courses.

三角洲相区分为三角洲平原、三角洲前缘和前三角洲三个亚相。

The Yellow River course shifts and subdelta formation are analyzed first, and the finger-shaped geomorphology system caused by the river course shifts is also analyzed systemically. The environmental factors such as meteorology, hydrology, DEM , vegetation, soil, soil salt content, and exploitation are all described and discussed.

综合分析了1855年以来黄河流路变迁和亚三角洲的发育演化，以及在此控制之下形成的三角洲指状骨架地貌体系；对黄河三角洲的气象、水文、地形、植被、土壤、含盐量等环境背景特征以及人类开发活动进行了深入探讨和分析。

With regard to the external Qinhuai River regulation project in Nanjing City, the inverse Gaussian distribution curve was determined as the flood level frequency curve of the river course by use of the frequency statistics technique, and the parameters λ and μ of the inverse Gaussian distribution were derived according to the current flood design standard.

结合南京市外秦淮河堤防整治工程，放弃传统的堤防潮位频率曲线线型，采用频率统计分析的方法确定了外秦淮河堤防潮位频率曲线的线型为反高斯分布；根据该堤防现行洪水设计标准推求了反高斯分布参数λ和μ。

The results show that rising of groundwater levels after water transportation plays an important role in the decreasing in the crown loss of Populus euphratica, and the crown loss of Populus euphratica gradually increases with increasing distance from the river course. The trees crown loss was less than 10%, which mainly was distributed within 100 metres to each side from the river course. The proportion of crown loss of overmature and effete forests were 50%-75% within 200 to 400 metres.

应急生态输水后地下水位的抬升对胡杨树冠疏失度的降低产生一定的作用；总体上，胡杨的树冠疏失度随着离河道距离的增加逐步增大，而且离河道越远，疏失度增加的程度就越大；树冠疏失度小于10%的旺盛胡杨主要分布在离河道100m之内，其中多以疏失度少于50%的长势较好的胡杨为主。

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。

Remote sensing data were applied to monitor the wetland landscape pattern in the Yellow River mouth. Our results showed that wetland vegetation and ecosystem are located symmetrically along the Yellow River. Vegetation and landscape are zonated from the coast land-inward and, perpendicular to this, according to an increasing distance to the river course.

运用遥感手段监测黄河口湿地景观空间分布格局，结果表明黄河三角洲自然保护区湿地植被与生态系统沿黄河呈轴对称分布，距黄河由远而近的规律性分布与由海向内陆的分布一致，依次是潮滩、翅碱蓬、柽柳、芦苇、草地和林地。

On the delta during Yellow River in zero,there developed a great number of slump structures,which might be formed near the edge of point bar and channel bar or in the channel developed whithin the point bar or channel bar,as well as in the river course.

黄河断流后三角洲上的滑塌构造非常发育，在分流河道中几乎随处可见，它们主要发育在边滩、心滩外缘、周缘或内部的水道中，还可以发育在河床上。

These machineries which develops for the adaptation different river course environment, although the model varies, but Wan Bian to its, its principle of work is not same, that is elects through the magnetic separation way the river sand in magnetic iron.

为适应不同的河道环境而开发的这些机械，虽然型号各异，但万变不离其宗，其工作原理是相同的，那就是通过磁选的方式将河沙中的磁性铁选出来。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
