与hydropower station相关的网络例句 [注：此内容来源于网络，仅供参考]

With the swift development of the hydroelectric project in our country, a set of large or extraordinary hydropower stations are being designed or constructed, such as the Three Gorges hydropower station, Longtan hydropower station, Xiangjiaba hydropower station, Xiaowan hydropower station, Pengshui hydropower station etc. All these hydropower stations adopt underground workshop, and have long diversion pipe system, and have one or two surge-chambers or adopt tailrace tunnel with sloping ceiling.

随着我国水电事业的迅速发展，一批大型、特大型水电站正在设计或处于待建之中，如三峡水电站、龙滩水电站、溪洛渡水电站、向家坝水电站、小湾水电站、乌江彭水水电站等，这些电站多采用地下厂房，具有较长的引水发电系统，并且设有调压室或采用变顶高尾水洞。

The objectives of this paper were to investigate the simulation and design of continuous multiple-station rolling forming process for a U-Section Steel Bar by CAE software-DEFORMTM Due to the limitation of elements number using a short strip 120mm went through all the stations to simulate the real continuous rolling forming on factory The roller gap was fixed as 0 30mm roll speed was 20 rad/sec and progressive angles were all equal for each rolling process which were the formed angle divided by by the number of station Three rolling processes were selected with 6 9 and 12 stations respectively During simulation processes two cases occurred Case A the strip was through a single station Case B the strip across two stations Because the strip laterals side was stretched and twisted during the process The model of case B closer to the practical process than case A and the calculated stress and strain on the tip of U section for case A were lower than these for case B by up to 15% From the result of case B for each process the stress for 12-station process was smallest 9-station process second and 6-station process next Because less-station can save larger cost and forming time but the bigger stress and strain for 6-station caused wrinkles on lateral sides not found on 9-station and 12-station Therefore 9-station process was a more suitable design than 12-station process smaller stretched and twisted and stress The progressive angles for 12-station was 7 5?

本文主要是以DEFORMTM有限元素软体模拟U型钢片连续道次成型与单一道次成型以确认单一道次模拟的是否可取代连续道次模拟之研究。因DEFORMTM 软体对於网格元素上的限制故使用较短素材120mm通过所有的成型站以模拟工厂实际连续成形方法。辊轮间隙固定为0 3mm；辊轮转速为20 rad/sec；弯曲角度的方法为将成型角度平均除以成型站数。有三种辊轮成型方式被选择分别为6站，9站，与12站。在模拟的过程中有两种现象会产生 Case A，素材通过单一成型站。Case B，素材会通过两个成型站。因为在模拟过程中素材的两端会有拉应力与扭力。Case B的模拟比Case A像实际的制程，并计算应力与应变在U型断面的Tip部中可发现Case A比Case B低约15%。从Case B的每站的结果可以得知，12站的成型应力最小，9站次之，6站最后。

As the clean, non-pollution, recycling utilized energy, small hydropower is an essential parts of Chinese strategy of continuous development. China offered a series of preferential policies on the different development periods of the small hydropower and the development of small hydropower had achieved outstanding accomplishment. Due to the absence of the social benefit and ecological benefit assessment in the economic assessment of the small hydropower, the netting electrovalence is irrational, the operation and maintenance on the small hydropower becomes difficult, and it will cause the lack of competitive ablility in the electricity market.

正因如此，中国在小水电发展的不同时期制定了一系列优惠扶持政策，小水电发展也取得了举世瞩目的成绩，但是就目前情况而言，由于小水电的经济评价中的社会效益和生态效益评价缺失，造成小水电上网低定价机制，从而导致了小水电站运行和维护困难，以及在电力市场中缺乏竞争力。
