Taking no account of aberrations,the optical spot size of the lens whose diameter is 1.80 mm is 1.2 μm.Compare the measurement value which is 1.5 μm with the theoretical one,they are almost identical with each others.It also proves the theoretical analysis is reasoned.

在不考虑像差的情况下，直径为1.8 mm的透镜其出射光斑直径为1.2 μm，利用狭缝扫描法进行了实际测量，测量值为1.5 μm，理论值与实验值基本吻合，从而说明理论分析的合理性。

Recorded with a fish-eye lens from a spot near the grandChteau de Chambordin France, the picture looks straight up, spanning almost 180 degrees fromhorizon to horizon.

这是在法国香波古堡，用鱼眼镜头所拍摄的全景相片，影像从一边的地平线涵盖到另一头的地平线。

I need to buy a new spectacle frame,but i wll keep the old lens.

我需要买新的眼镜框，不过我会留着旧镜片。

I need a new spectacle frame,however ,i will remain the old pair of lens.

我需要买新的眼镜框，不过我会留着旧镜片

Back in the fuselage, ASUS M530w built with 2 million pixel LED flash, although the camera does not support AF function, but it has a close-up, Scene settings, white balance, and other functions, and also with the dynamic camera video recording function In addition, next to the camera lens is the speaker hole.

在机身背面，ASUS M530w 内建 200 万画素与 LED 闪光灯，虽然相机并不支援自动对焦功能，不过却具备近拍、场景设定、白平衡等功能，且该相机也具备动态影片录制功能，另外，在相机镜头旁边则是其喇叭孔。

Limits to the minimum spot size, imposed by space-charge effect, emittance and spherical and chromatic aberrations of the lens, are investigated by means of a five-order radial trajectory equation, the K~V envelope equation and an analytical method.

理论上，利用推导的非线性轨迹方程、K-V包络方程及解析方法研究了空间电荷效应、发射度、透镜球面像差和色散像差对最小焦斑直径的限制并对聚焦实验布局和参数进行了优化选择。

This Say Cheese Blue Baby GUND Plush Camera features a snapshot sound mechanism and a mirror lens.

这个婴儿说奶酪蓝色gund长毛绒相机水仙花快照机制健全、镜子镜头。

Xiang Zhang and his colleagues at the University of California, Berkeley, used 36 precisely machined brass fins to create just such a lens for sound waves.

加利福尼亚周伯克利市大学的张翔以及他的同事用36片经精密加工的黄铜扇叶制作了这样的声波透镜。

The intensity of the ultrasonic wave will increase when the ultrasonic wave is focused by the sound lens in rock stratum.

然而 ，这种方法要受到两个因素的制约：一是增大超声换能器的功率，必然要增大超声换能器的尺寸，这在本身尺寸就很小的油井中是有一定限度的；二是当超声换能器辐射出的超声波的强度过大时，在超声换能器的周围要发生强烈的空化现象，产生大量的气泡，这些气泡将对超声波产生强烈的散射作用，导致超声波的衰减，反而降低超声波在岩层中的传播距离[1] 。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."
