Ionospheric absorption of cosmic radio noise

The development of the field of study of ionospheric absorption of cosmic radio noise since 1962 is reviewed. Contributions to the basic theory and methods of analysis are first dealt with. News concerning measuring technique are then briefly treated. In the main part of the paper the development of our knowledge of sudden cosmic noise absorption, polar cap absorption, and auroral absorption is reviewed. The emphasis is on the ionospheric effects. The solar disturbances associated with the absorption effects, the propagation of particles from the Sun to the Earth, and other extraterrestrial sides of the story are not treated.Part of this review paper was presented at the Second Symposium on Radio Astronomical and Satellite Studies of the Atmosphere, Boston, October 1965.     

Heat transfer behaviors of some supercritical fluids:A review

Supercritical fluids(e.g., hydrocarbon fuels, water, carbon dioxide, and organic working medium, etc) have been recognized as working media to improve thermal efficiencies in power cycles and energy conversion, and have been used or selected as the working fluids in engineering fields such as aerospace, nuclear power, solar energy, refrigeration, geothermal energy, chemical technology, and so on. To better understand the interesting characteristic or abnormal behaviors of supercritical fluids, m...

Plasma waves in the frequency range 0.001 – 10 cps in the earth's magnetosphere and ionosphere

The plasma model for the magnetosphere and ionosphere is first discussed. A review of some parts of the theory for a warm collisionless plasma of interest in the magnetosphere in connection with waves of periods between 0.1 and 1000 seconds is given. The theory for magnetohydro-dynamic waves in a slightly ionized gas is then summarized. The available observational data about magnetospheric and ionospheric phenomena, which may be interpreted in terms of waves with periods between 0.1 and 1000 seconds, are briefly surveyed and some theoretical applications to the ionosphere and magnetosphere are finally discussed. The theory of shock phenomena and transients in the magnetosphere is not included in the report.
