镜头

To improve the imaging quality of CCD camera and make the lens small in size,compact in structure,the wide field of view optical lens with the standard quadric surface and even aspheric surface was designed.

为提高CCD摄像机的成像质量，同时使镜头结构紧凑、小型化，在大视场光学镜头的设计中，引入标准二次曲面和偶次非球面。

AW: In general terms in the design of a lens the size of the lens can be minimized when the focal length and back focus distance are roughly equal.

伍尔兹：从总体上看在设计镜头大小的镜头时，可以减少焦距和背部重点距离大致相等。

"Fisheye:Of, relating to, or being a wide-angle photographic lens that covers an angle of about 180, producing a circular image with exaggerated foreshortening in the center and increasing distortion toward the periphery."

鱼眼镜头的：覆盖角度在180°左右、产生圆形图象且中央是夸张的使更向外围扭曲的透视图的广角摄影镜头的或与之有关的。

The film's famous final shot, a zoom in to a freeze frame, shows him looking directly into the camera.

影片最后的镜头很有名，一个变焦长镜头跟拍到他直视镜头定格为止。

Many episodes were actually a fricassee of archive footage spiced with more recent shots.

实际上，有许多集是用较多的近期镜头杂合在原存档镜头中形成的。

We needed that to be a full shot , so I said,"If we can't do it in one go, we can't do it."

我们想要一个全景镜头，所以我说，"如果我们不能一个镜头拍成，我们就不要拍了。"

In Sleep , he filmed stockbroker and poet John Giorno sleeping, in Vinyl Anthony Burgess' Clockwork Orange (with his assistant Gerald Malanga as the young thug), and in Empire , the Empire State Building for seven hours.

沃霍尔用固定镜头对着这幅画进行拍摄，坚持不使用闪光灯，并让一些人在镜头面前表演尖叫、抢劫、窒息……他甚至对着帝国大厦拍了整整7小时。

For example,when the camera moves from a sunlit to a shaded area within a shot ,it is often necessary to change exposure. The iris diaphragm of the lens can be changed,but this would change the depth of field and may be more noticeable than shutting down the variable shutter .

例如，一次摄像中当相机把镜头从阳光充足的地方移动到阴暗的地方时，必然需要改变曝光大小，镜头的可变光圈可以改变，但可能会影响景深，回比你关闭可变快门影响效果更大。

Carl Zeiss Jena, Germany-specialized enterprises, is to create photographs and film camera one of the world-class enterprises.

卡尔蔡司，德国镜头专门企业，且是制造照片和胶片镜头的世界级企业之一。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
