exosphere 翻译 exosphere 翻译基本解释 ●Exosphere:外大气层
Measurements of sodium resonance emission showed that the sodium exosphere of the Moon extends up to 1500 km. altitude above the equatorial limb. The line-of-sight sodium atom densities at various altitudes were derived from the measured sodium emission intensities, using a calibration based on ...

Atmospheres that are gravitationally bound to planets such as the Earth demonstrate a density gradient that decreases in density with an increase in altitude or height. Moving higher and into the exosphere, the atmosphere becomes so thin that the individual molecules that make up the air are so ...
Theexosphereis the outermost layer of the atmosphere (that is, it is the upper limit of the atmosphere) and extends from the exobase, which is located at the top of thethermosphere. The exosphere begins variously from approximately 2,300,000ft to 3,280,000ft above the surface, where it ...
Related to this Question What are the layers of the thermosphere? What extends for the mesosphere to the exosphere? Is the exosphere the coldest layer? What is the lower boundary of the exosphere called? Which layer of the atmosphere is located above the mesosphere?
“picked up” by the solar wind. We estimate that the neutral density required to produce the observed pickup ion fluxes is similar to typical exospheric densities found at ~700 km altitudes. We suggest that this event was most likely caused by a meteroid impact. Understanding meteoroid ...
Mars is an unmagnetized planet whose hydrogen exosphere extends into the solar wind, creating proton cyclotron waves. Mars Global Surveyor data reveal the occurrence of waves to be extensive and often intermittent at large distance, indicating that the exosphere is time varying or non-spherical. ...
MAIA is designed to determine the composition of Mercury's exosphere and possibly its crust. The mass resolution of MAIA is sufficient to resolve all elements up to mass 300 amu. In both optional modes the mass range extends from 1 to 100 amu, and, if required, it can be increased up ...
