查询词典 immersion lens

Battista della Porta in 1589, but it was not until 1611 that Kepler compared a lens of glass to the lens in the eye and showed that rays from each point of an object were brought to a focus at each corresponding point of an image on the retina.?

要注意not until的用法。参考译文：1589年B？巴第思塔？德拉？波尔塔出版了有关透镜的打磨与磨光的书籍，但是直到1611年，凯朴乐才比较了玻璃透镜与人眼的水晶体，并发现来自物体各点的光线都能在视网膜成像上找到对应的点。

Battista della Porta in1589, but it was not until1611 that Kepler compared a lens of glass to the lens in the eye and showed that rays from each point of an object were brought to a focus at each corresponding point of an image on the retina.

透镜可以集结更多的光束，并且依然可以象小孔一样成相，但是有一点两者不同，在小孔摄影机里，无论胶片与小孔的距离远近，光线都可以相成同样清晰的影像。

Generally, the Fresenl lens is used for collimation and its structure is planeconvex, but the analysis and comparison of the biconvex and the plane-convex Fresenl lenses with P-W method show that the biconvex Fresenl lens is better because of its specific imaging requirement. The two kinds of the Fresenl lenses were modeled in ZEMAX to validate the conclusion.

从应用角度看，菲涅尔透镜设计属于准直系统，一般采用平面结构，但由于其成像要求的特殊性，通过运用P-W方法进行分析和比较，结果表明：曲面的设计较之于平面更具优势，并在ZEMAX中分别对2种菲涅尔透镜进行建模，验证了结果的正确性。

The bifocus lens could produce images at the two independent focal length respectively and recovery the object's depth information according to the two bifocal images,which is the principle of depth estimating using bifocal lens.

成像物镜具有两个独立的焦距，通过对空间物体成像并进行分析可获取其深度信息，此即双焦测距的原理。

According to model, lead zinc ore bodies of mineral deposit, celestite ore bodies and gypsum ore bodies are distributed by the incomplete dome shape. The sandstone type ore bodies like a curved surface shape, is on the top, wide distribution, which like the top cover of a mushroom. The limestone breccia type ore bodies, under the sandstone type ore bodies, with mostly irregular vein shape, lens body shape, locate at the root of the mushroom. Gypsum and celestite ore bodies, accompanying with limestone breccia type ore bodies with the shape of vein, lens body, distribute under the sandstone type ore bodies.

根据模型显示，金顶矿床铅锌矿体、天青石矿体和石膏矿体呈不完整的穹隆状分布，砂岩型矿体在上，为曲面状，分布广，似一蘑菇的顶盖，而灰岩角砾岩型矿体分布局限，部分产于砂岩型矿体之下，多为不规则的脉状、透镜体状，构成蘑菇的根部；石膏和天青石矿体主要与灰岩角砾型矿体相伴产出，呈脉状、透镜体状，多分布于砂岩型矿体下部。

AE3000's memory enables the user to set the lens in a position for 2.35 widescreen Cinemascope viewing, and memorize that lens position.

AE3000提供镜头位置记忆，可以记住对于一个2.35：1屏幕，投射出2.35：1画面和16：9画面的镜头位置，之后，只要一键就可以在两种镜头设置之间切换。

The unsuspecting photographer focuses with the lens wide open to place the circle of least confusion at the sensor position b, and, taking the actual picture at a reduced aperture, he is unaware of the ensuing focus shift that prevents him from getting the best out of the lens.

一个经常使用全孔径来拍摄的摄影师会毫不犹豫地把胶片放在B点，但是如果他不改变胶片的位置，当他使用小光圈的时候，事实上，他就不可能充分利用这个镜头拍到最好的照片了。

We use only Nikon brand lenses to ensure consistent color balance and exposure accuracy from lens to lens.

我们只用尼康的镜头，确保每一个镜头有稳定的色彩平衡和精确的曝光。

A Galilean telescope is defined as having one convex lens and one concave lens.

阿伽利略望远镜的定义是一个凸透镜和一个凹透镜。

Convex lens and concave lens are two tpyes of familiar lenses.

常见的透镜有凸透镜和凹透镜两种。

Alternatively, the con- trollers can use the synchronous rectifier itself or loss- less inductor current-sensing methods to provide overload protection with lower power dissipation.

另外，康威特罗勒斯可以使用同步整流器本身或亏损减少电感电流检测方法，以提供低功耗过载保护。
