Whatever the wavelength of the radiation we study, we are still looking principally for those telltale emission and absorption . 不論我們研究的輻射具有什么樣的波長,我們始終以那些泄露天機的發射線與吸收線為主要尋找對象。

Along with ruby there are a great many other solid state lasers whose outputs range in wavelength from roughly 500 to 2500 nm . 除了紅寶石之外,還有許多其它的固體激光器,輸出波長從大約500納米(nm)到2500納米(nm)。

The resolution of a telescope is determined by the ratio of the wavelength of the radiation received to the diameter of the instrument . 一個望遠鏡的分辨本領取決于它所接收的輻射的波長對這個儀器本身的直徑的比值。

At infrared wavelengths the region is less opaque, and cool protostars are expected to emit most of their energy in the infrared . 在紅外波長范圍,暗云區是較透明的,而冷的原恒星應在紅外區發射其能量的大部分。

the spectrograph uses a concave diffraction grating that provides a wavelength dispersion of 4. 2a°/mm in the first order. 光譜儀用了一塊凹面衍射光柵,第一級光譜的色散度為42埃毫米。

Astronomers could gain only a biased idea of the universe when they were limited to the narrow wavelength band of visible rays . 由于只能在可見光的狹窄波段內觀測,天文學家關于宇宙的概念顯然只能是片面的。

Over the years solar physicists have amassed a large amount of data on “limb darkening“ as a function of wavelength . 多年來,太陽物理學家積累了“臨邊昏暗”作為波長函數的大量資料。

Progressively, larger objects substantially increase the timescale for collapse over still longer wavelengths . 進而言之,較大的天體,因要在更長的波長上坍縮,將大大增長時間尺度。

But the resulting rayleigh-jeans formula only matched the experimental curves in the very long wavelength region . 但是所得到的瑞利-勒斯公式只在波長很長的區域才和實驗曲線相符。

The electron wavelength is computed from the orbital speed required to balance the electric attraction of the nucleus . 電子波長是由平衡核力所必須的軌道速率計算出來的。

Simultaneous x-ray and infrared observations have exhibited the 4. 8hour period at both wavelengths . 同時進行的X射線和紅外線觀測證明,在這兩個波長均有48小時的周期。

Only discrete wavelengths of matter waves may resonate within the spherical volume of a hydrogen atom . 物質波在一個氫原子的球形體積內也只有一定的分立波才能發生共振。

The neon lights that adorn our city streets have a spectrum consisting of a few wavelengths near the red end . 使城市街道生色的氖燈的光譜由一些靠近紅色端的波長組成。

It shows well-defined wavelengths which are characteristic of the structure of the metal forming the anode . 它顯示出那構成陽極的金屬的結構所特有的,十分確定的波長。

The evidence seemed inescapable that light consisted of electromagnetic waves of extremely short wavelength . 光是由波長極短的電磁波組成,這一事實看來已經證據確鑿。

Each of the chemical elements that makes up the objects radiates at its own characteristic wavelength . 構成這些天體的每一種化學元素都會以它們特有的波長發出輻射。

we give the wavelengths of the k lines for some of the elements in table 2. 1, in units of cm. 表21中列出某些元素的K線波長,以cm為單位。

Because these wavelengths are so small, it is convenient to express them in terms of a small unit of length . 由于這些波長很小,因而用小的長度單位來表示更方便。

This might be compared with the jumble of wavelengths of sound that go to make up ordinary noise . 這種現象可以與合在一起構成普通噪音的聲波波長的混雜情況相比。
