The first is radiation from the sun, and this is particularly dangerous when the sun is very active and explosions are occurring on its surface. The second, less harmful form comes from the so-called Van Allen Belts. These are two areas of radiation about 1,500 miles away from the earth...
Solar radiation is also reflected from the Earth, and is scattered in the atmosphere, through both molecular scattering, called Rayleigh scattering, and scattering by particulate matter, called Mie scattering. Thus the atmosphere contains a mixture of radiation that is essentially scattered and ...
aA marketer is someone who seeks a response from another party, called the prospects. 去市场的人是寻找一个反应从另一个党的人,叫远景。[translate] aLife likes a play, but no rehearsals, also do not have the replay, play has come to an end, the more can\'t go back to see. 生活喜欢...
Eb is called the emissive power of a black body. The term “black body” should be taken with caution for although most surfaces which look black to the eye are ideal radiators, other surfaces such as ice and some white paints are also black at long wavelengths. Equation (15) is known ...
Thus it is concluded that analyses of ERBE data in terms of cloud forcing would add much needed insights into the role of clouds in the general circulation. With respect to the future, the scientific need is discussed for continuing broadband measurements of earth radiation budget data into the...
is seen among individuals who have been exposed to 50 mSv or more; this was determined on the basis of a study of atomic bomb survivors in Japan. The radiation dose from CT is not insignificant, and this becomes even more problematic in the patient who is young or potentially wants to ...
Radiation processes in the atmosphere play a major role in the energy and radiation balance of the earth-atmosphere system. Downwelling radiation causes heating of the earth’s surface due to direct sunlight absorption and also due to the back radiation from the atmosphere, which is the source te...
where (eλ)BB is the emissive power of a black body at wavelength λ and temperature T. The ratio eλ/(eλ)BB is called the emissivity of the body at the wavelength λ and eqn. (17.5) shows that emissivity = absorptivity at any given wavelength and temperature and is an alternative ...
can rotate as fast as 700 times every single second. And if they are blasting out jets of radiation that sweeps over Earth, like a beam from a cosmic lighthouse, the fast-spinningneutron staris called a pulsar. Neutron stars that rotate hundreds of times per second are called millisecond ...
