在中央

Among them is an approach that BrightSource uses, in which a field of small, flat mirrors called "heliostats" redirect and concentrate sunlight onto a central receiver at the top of a tower.

BrightSource 公司就在使用其中一项技术。该技术用名为&定日镜&小型平板镜片场改变阳光，使之聚合在塔顶端的中央接收器上。

This is particularly so when the concentrator has to track a moving incident source,for instance,to track sun in concentration solar power application using fixed target focusing heliostats.

譬如，在新型高倍太阳能聚光，塔式光热发电的应用上，定日镜场的每一台定日镜必须跟踪太阳并将太阳光反射到中央高塔的接收器上；为了提高聚光比和接收效率科学家考虑使用聚光式的定日镜，然而由于太阳跟踪的缘故其聚光器则必须在偏轴聚光的条件下使用，这就带来了光斑阔大即偏轴像差的问题。

In an open interest rate system, benchmark interest rate is the guide of all the money market. And also, it is the conference index for center bank to adjust monetary policy.

The character in the middle of the picture is the Lich King's mightiest Death Knight and also the legion commander. His army turned everything within their path to rot and decompose. His death coil drains the life-force from any who come in contact with it. He has no desires of the human beings. He is purely a tool of killing and conquering. Countless legions have been destroyed by him. His rapidly expanded forces are threatening the peace of the Red Land.

位于画面中央的是尸巫王手下最强大的死亡骑士也是军团指挥，他带领的军队所到之处天地变色，他拥有的死亡的光环能促使靠近的生命在短时间内老化，凋零，他没有人类的欲望，是最纯粹的杀戮和征服的工具，灭亡在他铁蹄下军团不计其数，他那日渐阔张军力正威胁着整个赤土大陆的和平。

Dreadlords live in heavily fortified lairs or march at the center of an army.

恐惧魔王一般都居住在经强化的沉重堡垒或者身处在一支军队的中央地带。

Their new home--30 square metres of grass witha lemon tree in the centre--must have felt like paradise.

它们在新家——一块30平米见方、中央有一棵柠檬树的草地——里一定感觉像在天堂一样。

Through the halls flowed a broad stream, and in it danced the mermen and the mermaids to the music of their own sweet singing. No one on earth has such a lovely voice as theirs.

一股宽大的激流穿过舞厅的中央，海里的男人和女人，唱着美丽的歌，就在这激流上跳舞，这样优美的歌声，住在陆地上的人们是唱不出来的。

They were then presented with an identical set of three lines on a fresh sheet of paper and asked this time to first mark the two ends of each line before marking the midpoints.

然后在另外一张同样的Ag纸上，先让患者标出他所看到的线段两端，然后再在标出的线段中央划一条垂直分隔线。

We also learned that both the CIA and the State Department attempted to keep Bush from referring in his 2003 State of the Union Address to Saddam's attempted purchase of "yellowcake" uranium from Niger.

我们还了解到，无论是美国中央情报局和国务院试图保持布什在谈到他在2003年发表的国情咨文对萨达姆的企图购买&黄饼&铀来自尼日尔。

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.
