例句與造句

1. High current densities produce continuum emission and tend to favour shorter wavelengths.
2. Higher current-densities begin to produce continuum emission.
3. This method produces the continuum emission, and is more prominent at higher current-densities.
4. In addition to HI gas, it is thought that radio continuum emission should be present from NGC 5238 as well.
5. The radio continuum emission along the galaxy's major axis is asymmetrical, being brighter in the southwestern part than in the northeast.
6. It's difficult to find continuum emission in a sentence. 用continuum emission造句挺難的
7. The H II and recombination lines vary very strongly, with continuum emission ( electromagnetic radiation across a broad band of wavelengths ) less affected.
8. The radio frequencies accessible to this telescope range from 180 to 700 GHz which includes rotational transitions of dozens of molecular species as well as continuum emission from interstellar dust grains.
9. Based on this, it is to be expected that there should be radio continuum emission from the galaxy, due to the acceleration of electrons in HII regions, known as bremsstrahlung.
10. They are also observed in X-ray emission from their hot interiors, in optical line emission from their ionized shells, and in infrared continuum emission from dust swept up in their shells.
11. It is found by forming a rectangle with a height equal to that of continuum emission, and finding the width such that the area of the rectangle is equal to the area in the spectral line.
12. Optimum output-efficiency in the visual range is obtained at a density that favors " greybody radiation " ( an arc that produces mostly continuum emission, but is still mostly translucent to its own light ).
13. Spectral line emission is usually chosen when pumping Nd : YAG with krypton, but since all of xenon's spectral lines miss the absorption bands of Nd : YAG, when pumping with xenon the continuum emission is used.
14. This has two important consequences : First, to accurately measure the energy output and structure of objects that are obscured by dust, far-infrared continuum emission ( emission across a broad band of wavelengths ) must be included.
15. RHESSI provides spatial resolution of 2 arcseconds at X-ray energies from ~ 4 keV to ~ 100 keV, 7 arcseconds to ~ 400 keV, and 36 arcseconds for gamma-ray lines and continuum emission above 1 MeV.
16. Notable scientific achievements included : the significant Westerhout Catalog of continuum emission radio sources, by which " W " numerical designations such sources are still referenced ( see for example Westerhout 49 ), done with the then-new Dwingeloo telescope; and his survey of neutral hydrogen in the outer parts of our Galaxy.
