 “一般坝”译为未确定词的双语例句
 The method presented in the paper is not only of great importance to instruct the anti seismic design of wasteland, but also valuable to the design of ordinary dams and embankments. 这一方法对一般坝体的工程抗震也有很大的参考价值 短句来源 The existence of the we ak solution is proved by penalty method，i. e. it is proved with Schaud er fixed-point theorem that the solution of the penalty problem exists and finally the existence of the weak solution is done. 考虑一般坝的承压无压渗流问题，导出其弱形式问题．用惩罚方法证明了弱形式问题解的存在性，即用Schauder不动点定理证明其惩罚问题的解是存在的，最后证出弱解的存在性． 短句来源

 ~~ 本文介紹了在坝体結构动力分析中利用靜力模型試驗結果的三个具体实例。这三个实例是:大头坝橫向地震力的分配、大头坝坝垜横向自振周期的研究及拱坝自振周期的确定。在后二个实例中用本文所述方法求得的結果,与动力模型試驗及坝体原型实測的結果相当接近。我們认为,这种方法值得在解决一般坝体結构的动力分析的其他問題中得到更广泛的应用。 A lot of reservoirs have been built in China. Among them, there are 16 larae-scale reservoirs with high dam of more than 80 metres and storage capacity of no less than 2 billion cubic metres. He-yuan earthquake with magnitude 6.1 occured at xinfengjiang Reservoir of Guangdong province in 1962 caused great attention domestically and abroad. So, it is very important to study earthquake countermeasures for reservoirs, especially the large-scale reservoirs. 中国疆土辽阔,水库众多,仅坝高大于80米、库容超过20亿米~3的大型水库就有16座。为了减轻大型水库的地震灾害,作者提出了几点地震对策。一是坝址选择对策。关键问题是在水库选址时,要进行活动断层调查和潜在震源判定,二是水库地震评定对策。对破坏性水库地震(Ms≥5)发生条件,作者提出了三条评定标标:1.大型水库,一般坝高要超过80米,库容要大于20亿米~3;2.活动断层,在库坝区(半经约25公里)存在大的活动断层;3.活动地震带,首先,库区要在地震带上,这里有中强地震的历史记录或潜在震源;其次,水库所在地震带当水库蓄水时,正好处于地震活动期。 The technique of then-lift and whole-block placement without vertical joints was applied in construction of Wuqiangxi Hydropower Station. The average block area of dam sections was 1300--1600m2. The maximum reached 2178m2, which was located on dam section with the ship lock. It was successful to use four large comprehensive mechanized construction systems which supported the concreting. The temperature control measures of concrete were successfully selected. These achieved international advance. 五强溪水电站大坝混凝土采用不分纵缝的通仓薄层浇筑施工新技术，一般坝段通仓面积为１３００～１６００ｍ２，最大通仓面积（位于船闸坝段）达２１７８ｍ２。施工中所采用的与通仓薄层浇筑配套的大型高速综合机械化施工的四大系统，以及所采取的混凝土温度控制措施是成功的，达到国内先进水平。 << 更多相关文摘
