水流

Will come to rui Fang town water nan hole gold waterfall ,this seat at road side recite lean on have not ear teapot mountain cascade waterfall, because includes abundant pyrite with sulphur arsenic copper mine, lets earths surface submit golden, too is form yin and yang seas chief water source, ases gallop waterfall current let out but under shi jiu Like a piles up with gold mines waterfall, dazzling affecting, a screen limpid water curtain of straight rush gold yellow earths surface let people for a time rise play water idea, justs because heres water quality include huge amount of heavy metal material, for oneself safety, or prudent, gold waterfall locates in square self-improvement bridge side and long benevolence digging under this mountain six pithead, because in the early time at headstream picks up copper mine, mountain spring water with rainwater infiltration, slag sand deposits stream bed, and has fungus adhere multiply, hypsography differences compares big so form gold yellow waterfall spectacular sight, gold waterfall is gold melon stone local very characteristic a scenic spot, usually too very easy meets come this place screen nuptial dress new one.

来到瑞芳镇水湳洞的「黄金瀑布」，这座位在公路旁背倚无耳茶壶山的层叠瀑布，因含有丰富的黄铁矿与硫砷铜矿，让地表呈金黄色，也是形成阴阳海的主要水源，当奔腾的瀑水流泄而下时就像是一座堆满金矿的瀑布般，耀眼动人，一幕清澈的水帘直冲金黄色的地表让人一时兴起玩水念头，不过由於这里的水质含有大量重金属物质，为了自身安全，还是三思而后行，黄金瀑布位於本山六坑口下方的自强桥畔及长仁矿区，因为早期在上游采铜矿，山泉水与雨水渗入，矿砂沉积溪床，又有菌类附着滋生、地势落差较大所以形成金黄色的瀑布奇观，黄金瀑布是金瓜石当地很有特色的一个景点，平时也很容易遇到来此地拍摄婚纱的新人。

If an individual is crossing alone in swift current, he can keep his balance best by using an ice ax or a sturdy tree branch as a third point of support for contact to the stream bottom upstream from his feet.

如果一个人要通过水流很急的溪谷时，使用冰斧或强固的树枝当作第三个支撑点，称在上游方向，这样能提供最佳的身体平衡。

If two men cross, the taller and stronger member will use his ice ax as a third point of contact and will be the upstream man, facing upstream and breaking the force of the flow for his partner who also faces upstream and hangs onto the hips or belt of the upstream man.

如果是两人渡溪，较高与较强的人用冰斧作第三个支点站在上游方向，面向上游将水流的力量打散，在下游方向者也要面向上游，手则抓在上游者的腰部或腰带上。

This article introduced the general situation of the domestic and international ice jam research and the necessity of the water level research firstly.

文章首先介绍了国内外冰情研究的概况以及进行冰塞水位研究的必要性，接着，详细论述了冰盖的形成条件及形成过程，冰塞的形成机理及冰塞在空间发展的一般规律，由冰塞所引起的水位变化过程，影响冰塞水位的河势因素、热力因素、水流动力因素及人为因素等。

In this paper, flume experiments on the formation of initial ice jam thickness and its varying mechanism were carried out, brought to light the relations between factors of initial ice jam thickness, flow condition and ice discharge etc..

本文通过水槽试验，对初始冰塞厚度的形成及变化机理进行了试验研究，揭示了初始冰塞厚度与水流条件和冰流量等因素间的相互关系。

This article introduced the general situation of the domestic and international ice jam research and the necessity of the water level research firstly. In succession, discussed the formation condition and the formation process of the ice cover in detail, the ice jam formation mechanism and the general regulation of development in the space, the water level variety process that caused by ice jam, factors that influence the ice jam water level: the river power factor, the thermodynamic energy factor, the water current dynamical factor and artificial factor etc..

In the paper, river and the downstream area of dike are regarded as a whole system, and hydraulic model of coupling 1-D river and gradual dike-break is established, therein the Preissmann implicit difference scheme is applied to Main River, and the FVM is applied to the breach and polder. On the basis of FVM and unstructured grids, TVD ?

本文将河道与堤坝下游区域视为一个整体，对于单一河道采用Preissmann四点隐式差分格式计算，对于溃口及圩区采用有限体积法，建立了一维河道与堤坝渐溃耦联的水力模型，也是一维、二维耦合的水流模型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
