IOS(infinite order sudden) approximation,the hyperfine collisional transitional rate coefficients of E - type CH3CN - H2 have been calculated under the conditions of interstellar molecular clouds.
For perfecting plasma control technique, the mecha- nism of plasma cloud current in plasma arc welding is studied on the basis of physical theory of plasma. Analyzing the reason of producing the electric current with probe.
This text has introduced some safe evaluation methods of the fuzzy safe evaluation, DOW chemical fire and explosion, pool fire , Vapour Clound Explosion(VCE) , (Boiling Liquid Expanding Vapour Explosion )BLEVE model and fault tree analysis(FTA),etc.
It includes three steps: first, the cloud data are preprocessed for smoothing; second, a helical line is segmented to form triangle meshes; and third, Bezier surface patches are created over a triangle mesh and trimmed to shape on an entire surface.
The results of studying the interaction of two types of the solar wind (magnetic clouds and solar wind of extremely low density) with the Earth's magnetosphere are discussed.
Inner layering is revealed in the upper layer of the clouds of the planet at altitudes of 61.5-65.0 km, which is specified by an enhanced turbulence of the atmosphere.
An analysis of the observations suggests that the tilted current sheet is draped within the overlying cloud canopy, ahead of a magnetic cloud-like structure.
The gravitational field and the motion of matter in the universe are investigated according to Einstein's field equations and his dynamical equations of motion. In a spatially isotropic and homogeneous space-time continuum it can be shown that up to about 2x10~8 l.y. the following relation holds between spectrum displacement δλ from distant spiral nebulae and their observa-tionally defined distance d,where A is Einstein's cosmological constant. The first term on the right hand side is essentially Hubble and...
The beta-ray spectrum of RaE was investigated by the cloud chamber experiments. About 600 tracks with H σ above 2000 were obtained. The spectrum was found to have an end point at 7500 Hσ. The average energy per disintegration was estimated to be 4.01×105 electron-volts.
1. This paper deals with the blood-sucking Ceratopogonidae collected fromSzechuan province.2. The female flies. of Lasiohelea taiwana, Culicoides sugimotonis and Culi-coides oxystoma have been studied morphologically in detail. Apart fromTaiwan Province, these species are recorded for the first time in China.3. The proportional length of the antennal segments, the shape of sonsorypore of the maxillary palpus and the distribution of wing spots are thespecific characters for the identification of these specie...
