探测器

Inaugurating the era of space exploration for the United States, Explorer I was a thirty pound satellite that carried instruments to measure temperatures, and micrometeorite impacts, along with an experiment designed by James A.

开辟美国太空探索的新纪元的探测器Ⅰ是一枚重30磅的卫星，它携带了测量温度和微陨星碰撞的仪器，还有一个由James A。

Dynamic smoke aerosol of five European standard test fire,including open wood fire(TF1),smoldering cotton fire(TF3),polyurethane fire(TF4),N-heptan fire(TF5),and methylated spirits fire(TF6),was measured by Scanning Mobility Particle Sizer Spectrometer,and smoke particle size distribution and particle number concentration were recorded and analyzed for studying the smoke dynamic coagultion effect.

结果表明，在火灾探测器做出响应之前，正庚烷明火的烟颗粒粒径主要分布在100~500 nm，木材和聚氨酯明火及棉绳阴燃的是50~400 nm。

This paper designs one kind of mineshaft portable gas detector in view of the present situation, when the gas gas density approaches the dangerous value, automatically sends out reports to the police, the reminder mineshaft personnel leaves immediately.

本文针对目前情况设计一种井下便携式瓦斯探测器，当瓦斯气体浓度接近危险值时，自动发出报警，提醒井下人员立刻离开。

A new three-detector litho logy density tool appears. It can correct the influence of thin beds and obtain photoelectric absorption coefficient of formations more exactly.

於是，出现了一种三探测器岩性密度测井仪器，这种仪器可以对薄层进行校正并能更准确地求取地层的光电吸收截面系数。

The pitch of the array of detectors (1) is smaller than the pitch of the incident intensity pattern so that the latter is oversampled, yielding high accuracy.

探测器阵列(1)的间距小于入射强度辐射图的节距、使得后者被过抽样，由此得到高精度。

Launched into Earth's orbit by an Ariane-5 booster rocket from Kourou, French Guiana, in September 2003, SMART-1 used its ion engine to slowly raise its orbit over 14 months until the moon's gravity grabbed it.

2003年9月，&智能1号&探测器从法国圭亚那地区的库鲁基地由Ariane五号火箭发射升空，在其离子引擎的推进下，&智能1号&缓慢脱离运行轨道，在14个月后进入月球重力场。

A He-Ne laser is used as a light source, and a photomultiplier tube as a detector.

使用He-Ne激光作为光源，光电倍增管作为探测器。

The detector consists of two layers of LSO crystals and a position sensitive photomultiplier tube .

这个探测器是由两层氧正硅酸镥晶体晶体和位置灵敏型光电倍增管组成。

The photomultiplier tube responding to direct neutron irradiation has an extreme effect on the scintillation detector design and its practical applications.

光电倍增管的中子直照响应对脉冲中子探测器的设计和实际应用具有重要影响。

These detectors are low impedance devices, typically 10 to 150 ohms, and require a low voltage noise preamplifier.

这些探测器是低阻抗器件，通常是10至150欧姆，而且还需要一个低电压噪声前置放大器。

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。
