尽管这在都柏林区是罕见的，然而还会有缺衣少食的亡命之徒埋伏在荒郊僻野处，把手枪顶在安分守已的路人头部加以威胁。他们可能像泰晤士河堤岸上那些饥饿的穷流浪汉似的到处荡来荡去，对你进行突然袭击，逼你交出钱来，否则就要你的命。把你抢个精光之后，还往你嘴里塞上东西，脖子用绳索勒起，把你丢在那儿，以便警告旁人，他们就逃之夭夭。

Results the image data of spiral CT have been sent into PACS and recorded in CD-R At any moment the pictures of image data can be shown on terminal, can be applied to make teaching lantern slide by Power Point and to make multimedia teaching software by Authorware.

结果 ：运用FTP软件把工作站里制作好的彩色图像信息传入PC机并进入我院PACS系统进行光盘刻录，存储于光盘塔中，可随时用PACS系统中的任一PC机调出，用ACDSee32、Photoshop、Win98 映象等软件显示和打印彩色图象，用Powerpoint来制作教学幻灯片，用Authorware来制作多媒体教学软件。

The image is first reduced in dimension by Gaussian pyramid, and the Hu moment is applied to the fixed sized overlapping blocks of low-frequency image. The eigenvectors are lexicographically sorted. Then, similar eigenvectors are matched by a certain threshold value. Finally, the area threshold value is proposed to remove the wrong similar blocks. The mathematical morphology operations are performed to locate the tampered part.

该算法首先将图像进行高斯金字塔分解，将低频图像进行块分解，提取每块的Hu矩不变特征，并将特征向量排序，然后为每个特征向量搜索符合阈值的相似特征向量；最后利用区域面积阈值去除错误的相似块，并结合数学形态学定位篡改区域。

By analyzing the relationship between the deforming precision of Active Lap and corresponding force generated by moment actuators, a new structure of Active Lap for manufacturing a Φ1800mm, F/1.5 large paraboloidal mirror is obtained. Its progressed performance has been proved with 60 units micro-displacement sensor array.

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。
