波段

Since we are stuck inside, and since opaque dust truncates our view in visible light, nobody knows for sure.

因为我们局限在银河内部，也因为不透明的尘埃在可见光波段挡截了我们的视线，所以没有人确实知道银河的模样。

Q1 is the active device. the antenna is capacitively coupled to L1. L3/VC1 forms the tunned circuit (to the 40meter band, SW). and the RF signal is fed to Q1's gate.

Q1是有源器件，信号经过L1耦合到L3/VC1的调谐电路中（40米波段，SW），射频信号输入到Q1的门极。

Tunning a reflex klystron oscillator tracking the resonant frequency of the cavity to be measured automatically by means of a discriminator. The oscillation frequency of this system$...

然后利用一高精度外差式频率计来测定该振荡系统的振荡频率和经摄动后的频率偏移计算和实验表明，用本文所述方法，当被测腔固有品质数为500～1000时，在S 波段可以分辨的最小频偏相对值达10－5～5×10－6跟踪误差约为2％。

Stepwise Discrimination Analysis was applied to estimate the reclamation levels of coastal soil using the nine absorption bands.

依据不同围垦历史，对所有土样进行分组，并对选取的9个吸收波段进行逐步判别分析。

Both crystal and ceramics show typical Ce3+ absorption bands at 230,340 and 460 nm and a 540 nm emission peak.

Ce：YAG晶体和陶瓷都具有位于230，340和460 nm波段的Ce3+离子的特征吸收带和540 nm附近的发射峰，但Ce：YAG晶体同时存在296和370 nm的色心吸收，其发射峰位于398 nm，而透明陶瓷中不存在。

The change of apple florescence spectral features and the target information of apple flower/leaf and apple flower/tree present a good correlation, and it indicates that the sensitive wave band range is 400-530 nm cyan light, 570-700 nm orange-red light, and the 760-1350 nm nearly infrared of medium flower/tree of apple trees.

其光谱特征变化与花叶比和花树比指标呈现较好的相关性，敏感波段范围为400~530 nm的蓝青光和570~700 nm的橙红光，以及中等花树比果树760~1 350 nm的近红外。

Taking Qixia City as the research region, using supervised classification of the flowering apple digital photos to extract the target information of the ratio of apple flower/leaf and apple flower/tree, this paper carries out the correlation analysis of the ratio data with synchronization hyperspectral detection data, to determine the spectral features and sensitive spectrum wave band of the apple florescence.

以栖霞市为研究区，利用苹果花期数码照片监督分类，提取苹果花树比和花叶比指标信息，通过与同步高光谱探测数据的相关分析，研究苹果树花期光谱特性，确定其敏感的光谱波段。

The study on spectrum analysis of arc sound signal has showed that a signature band of 5-10kHz of sound wave would be generated before fault s arc take place, which is strong in intensity and variable in both width and center depending on arcing electrodes, space between electrodes, and discharge volt age.

早期弧声的功率谱分析表明，故障电弧发生之前，在可听波段产生5kHz~10kHz的电弧声，其带宽和中心频率与电极形状、放电距离、放电电压等试验条件有关。

Judging from the industry restructuring, coal, and financial and insurance industry is the fund manager band operation two major industries, food and beverage and transportation industries, such as weak cycle Opening a gradual trend, metal non-metal industries showed a substantial reduction.

但从产业结构的调整，煤炭，金融和保险业，基金经理波段操作两大行业，食品和饮料，交通运输行业，如弱周期打开一个渐进的趋势，金属非金属业表现出大幅度减少。

DXing on the high bands is like shooting fish in a barrel.

在高波段通联DX就像在一个桶子里打鱼。

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。
