ANNOUNCED AND PRESUMED NUCLEAR EXPLOSIONS IN 1963–1976ELSEVIERMonitoring Underground Nuclear Explosions
摘要: Large nuclear explosions in the solid earth, the hydrosphere, and the lower and upper atmosphere have generated seismic waves of periods greater than about 5 seconds which have been detected at great distances from the source.关键词: general and miscellaneous atmosphere-- detection-- earth-...
We know two kind of stellar explosion events; shock induced explosions of core collapsing massive stars known as type II supernovae, and accretion induced thermonuclear explosions such as typeIasupernovae, X-ray bursts, and novae in accreting binary systems. The type II supernova shock front ...
from five nuclear test explosions in Novaya Zemlya during the summer of 1962 are given. Notable differences exist between some of the records. These may be due to differences in the heights of the explosions. Dispersion curves of group velocity against period are shown. Waves ranged in period ...
This point is best illustrated with the example of Hiroshima and Nagasaki in Japan,the nuclear explosions was occurred (不用被动语态) nearly a half century later,the residual nuclear radiation badly has been endangered the natural ecosystems in the native....
The review of the results of time analysis at the range of high-energy nuclear collisions (with the bombarding-particle energies near 0.1 - 10 GeV/nucleon) is presented. It was shown that the formation of time resonances (explosions) in the decays of compound nuclei or final clots at the ...
We turned to radiation expert Dr. Andrew Karam, a radiation safety professional with more than 30 years of experience. Karam takes us step by step through what happened during the nuclear shutdown at Fukushima—and what went wrong.
The nuclear decay properties of heavy nuclides ( A ≤ 257 ) produced in two low-yield thermonuclear explosions, the Par and Barbel events, have been studied with the following results: The α -decay branching of Cf 253 has been observed, E α = 5.978 ± 0.005 MeV, α ( α + β - ...
We present the origin of the equivalence of feature space and phase space based on the determination of the minimum of uncorrelated features and the choice of training samples in the seismic pattern recognition of underground nuclear explosions.The validity of feature space and phase space is tested...
