两分

Supporters point out that the two dams will flood an area only one-sixth as large as that inundated by the giant Itaipu dam. But because of their modern turbines, and the strength of the Madeira's flow, they will generate electricity equal to 8% of Brazil's current output.

拥趸们指出，与巨大的 Itaipu 水坝相比这两个水坝的泄洪区面积仅为前者的六分之一，但是由于采用了现代化涡轮机，加上马代拉河的汹涌水流，两水坝的发电量将达到巴西目前电力产出的8%。

September 30, 12.45pm, Camp Bahariya- Last two competitors, Laurie Brophy from Wales and Peter Clarke from Hong Kong can be seen about 2 miles away from the finish line, with the camel sweepers.

09/30 12：45 pm (从出发时间 09/29 05：00 am 算起已经 31 小时 45 分)，最后两位跑者，英国威尔斯的 Laurie Brophy 和来自香港的 Peter Clarke，由骑骆驼的大会工作人员追随，离终点只剩两英哩了。

He rejoined the Communist League and wrote two lengthy pamphlets on the 1848 revolution in France and its aftermath, The Class Struggles in France and The 18th Brumaire of Louis Bonaparte .

他重新加入了共产主义者同盟，并写了两篇长长的文章来总结1848年欧洲革命的经验，这两篇文章分别是 The Class Struggles in France and The 18th Brumaire of Louis Bonaparte 。

Numerical simulations of the three dimension viscous flow over the SUBOFF-1 model provided by DARPA and other two models are processed by solving RANS equations withκ-εtwo-equation turbulence model and finite volume method, and with SIMPLEC method for pressure-linked terms, central difference shemes for temporal derivative terms, and second-order upwind schemes for convective and diffusive terms.

本文基于RANS方程，采用κ-ε两方程湍流模型来封闭控制方程，采用有限体积法离散控制方程，对于速度压力关联方程，应用协调一致的SIMPLEC算法求解，变化率项用中心差分，对流扩散项采用二阶迎风格式，分别对DARPA提出的裸艇体SUBOFF-1模型以及另外两种回转体模型进行了数值模拟计算。

The border of Ehuling group and Daguding group was renewed.it concluded that volcano rocks of former subcycle and latter subcycle volcanic activities all came from the same source of magma,according to their chemical compositions and their chondrite normalized REE patterns.

对如意亭剖面鹅湖岭组与打鼓顶组的界线进行了重新厘定，对早晚两个火山活动旋回火山岩的化学成分、稀土配分特征进行了比较，得出了两旋回火山岩系属同一岩浆源的不同阶段演化产物的认识。

The structure theorem is obtained by defining "ternary ordered partition method" which is used to choose the test-sets of the first $k$ tests, and by defining two operations and two relations on feedback sequences; The isomorphism classification theorem is strictly proved by virtue of the structure theorem, thus the complicated problem of discussing $3^k$ possible search domains is reduced to the relatively easy problem on $k+1$ representative search domains; By the techniques of "super-coin construction method" and "image-union method", the search problem on $k+1$ representative search domains is reduced to the simple verification of several conditions on finite space of small cardinality.

通过引入用于选取前$k$次试验的试验集的"三元有序剖分法"以及关于反馈序列的两种运算和两种关系，得到了结构定理；基于结构定理严格地证明了同构类定理，从而将必须针对$3^k$个搜索域的复杂问题转变为讨论$k+1$个具代表性的搜索域的相对简单的问题；通过"构造超币法"和"并像法"等技术手段，将关于$k+1$个具代表性的搜索域的搜索问题转化为简单的关于势非常小的有限空间的几个条件的验证问题。

This paper researches linear maps preserving orthogonality,obtains the linear maps preserving othrogonality,it is either a rank -declining or rank -keeping map or a map with nilpotent element in its codomain.

利用分块成向量的方法证明了MnMn(F为域F上所有n×n矩阵构成的乘法半群上的n×n拟正交矩阵组至多含有n个矩阵，利用方程组的解的理论证明了Mn中与给定矩阵A构成两两拟正交矩阵组的矩阵个数不超过n-Rank+1，从而得到Mn上保持拟正交性的线性映射φ要么是降秩的或者保秩的映射，要么φ的值域中含有幂零元。

In fact, just like during the first stage and for the same safety reasons, the competitors will be tackling two routes starting from Cordoba.

事实上，出于安全考虑，和上个赛段一样两组参赛者从Cordoba出发开始就分两条道路行驶。

To resolve this problem, we'll reel outwards drive across the bridge to the intermediate surface of variable-speed drive wheel with two wheels of processed into 30 °, the increase in friction with Groove, even if such a belt would not have had; the diameter of 6 mm, spin out to o-rubber belt changed out with Burr corn-cob o-shaped belt; crossing the bridge to another variable-speed drive belt pulley to roll out of the book, two rounds of the belt pulley turned into 1/2 inch, using chain drive sprocket, and fixed machinewe side wall to cross the bridge wheel seat side wall plate processing growth holes for adjust tension pulley and sprockets.

为解决这个问题，我们将分切机朝外传动面传动到中间过桥变速皮带轮的两轮加工成30°的带槽，增加摩擦力，这样皮带即使松了也不会打滑；直径6mm的O型橡胶皮带改成外面带毛刺的聚氨酯O型皮带；过桥变速皮带轮的另一个传动到出书辊的皮带轮，两轮改成1/2英寸的链轮，采用链条传动，再将固定在机器侧墙板的过桥轮座侧墙板孔加工成长孔，可任意调整皮带轮与链轮的松紧。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
