探测器

Though unstable, many meson s last a few billionths of a second, long enough to be observed with particle detectors.

介子虽然不稳定，许多介子只存在10亿分之几秒，但用粒子探测器已足以观察到它们。

On condition that, the radiant emittance value of detector surface was researched , in a certain distance to blackbody.

在此基础上对与黑体有一定距离的探测器表面辐射度值进行了研究。

In this dissertation,preparation and thermoelectric characterization of conventional silicon-based materials and devices have been studied, including amorphous silicon films, polycrystalline silicon germanium films and amorphous silicon thin-film-transistors. A novel MEMS-IC integration method based on porous silicon micromachining has been developed, which is used to fabricate resistive bolometers with a-Si and polySiGe films, and a-Si TFT-based room-temperature infrared detector pixels and 8×8 arrays with primary capability of thermal imaging have been reported for the first time.

本文深入系统地研究了a-Si薄膜、polySiGe薄膜和a-Si TFT等三种常规硅基材料和器件的制备方法和热电特性，开发了一套新型的基于多孔硅牺牲层技术的MEMS-IC集成工艺，利用该工艺成功地制作了a-Si和polySiGe薄膜电阻式测辐射热计，在国际上首次提出并实现了基于a-Si TFT的室温红外探测器单元与8×8阵列原型，器件初步具备了室温红外热成像的能力。

The results show that the maximum detectivities of a-Si and polySiGe bolometers are 2.23×108 and 3.75×108 cmHz1/2W-1 respectively, and TFT-based room-temperature infrared detectors have a maximum detectivity of 1.02×109cmHz1/2W-1, which reaches the same highest level in performances in the world.

结果表明，斩波频率为30Hz时，a-Si和polySiGe测辐射热计的最高探测率分别达到2.23×108和3.75×108cmHz1/2W-1，TFT室温红外探测器的最高探测率可达1.02×109 cmHz1/2W-1，达到目前国际先进水平。

The main difference between SH-60B and F is the way they fight against submarines. The B version mainly depends on the sonars on the CG and DDGs to find the targets, then it flies to the suspect area, using 25 tubes sonar buoyages and magnetism detector to make sure the target position for following combat using torpedo. The F is used for short range anti-submarine purpose around the carrier and depends on its own AQS-13F suspensory sonar to detect the submarine.

SH-60B和F型之间的主要区别为他们反潜的方法不同。B型主要依赖巡洋舰和驱逐舰上的声纳发现敌潜艇，然后飞近可疑区域，使用其25管的声纳浮标和磁异常探测器对目标精确定位，随后发起鱼雷攻击。F型则用于航母周围的短距反潜，主要依赖其AQS-13F悬吊声纳探测雷达。

And that would be Sharon Burks.

如果我们只能用空间探测器送一个人去与外星物种会面的话，我要选丹尼斯。

"Thisis a bolder, more aggressive objective than we have had before," saidJohn Callas, the project manager for both Mars rovers at NASA's JetPropulsion Laboratory in Pasadena, Calif. It's tremendously exciting.

&这是一个大胆，更积极的目标比我们不得不说，&约翰卡拉斯，项目经理两个火星探测器美国宇航局喷气推进实验室的科学家，加州这是非常激动人心的。

The measurements clearly pointed the way to optical communication compact gallium-arsenide semiconductor lasers as the source, low-cost cladded glass fibers as the transmission medium, and silicon or germanium semiconductors for detection.

测试结果清楚地指出了光通信的道路--就是以紧凑的砷化镓半导体激光器为光源，廉价的包层光纤为传输媒质，硅或锗半导体为探测器。

China nearly 10 scientific research institutes and universities and college teachers and students participated in all the large collider detector construction and data analysis.

中国近10所科研院所和高等院校的科研人员和高校师生参加了对撞机上所有大型探测器的建造和数据分析。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
