A method for the automatic inversion of resistivity soundings is presented. The procedure consists of two main stages. First, application of linear filters which transforms the apparent resistivity curve into the kernel function, and vice versa. In the second stage the first and second derivatives of the kernel function are calculated and used in a second-order modified Newton-Raphson iterative fitting procedure. The model obtained is optimal in the least squares sense. The method has been tried on some field examples and produced resistivity models which show a good agreement with the geological well logs. 相似文献

Radiation from the Magellanic Clouds is discussed from the point of view of near future possibilities in observational γ-ray
astronomy. The γ-ray fluxes expected according to the metagalactic and galactic theories of the origin of cosmic rays are
compared. It is shown that the strongest test of the metagalactic hypothesis will be provided by a determination of the ratio
of γ-ray fluxes from SMC and LMC. The γ-ray luminosity of a typical young supernova remnant that can generate sufficient antiprotons
is estimated. It is shown that such remnants must have a short phase during which they are very powerful γ-ray emitters. 相似文献

In this paper, anomalies of freezing of the European Russia’s rivers in 2006–2007 are considered. Multiyear observation data are used for analysing of trends in time series, which express terms of the first floating ice appearance in the European territory of Russia. It is shown that, in the end of the 20th and beginning of 21st centuries, a tendency of later freezing of rivers in this territory was detected. Linear equations that describe temporal trends were obtained for various rivers. Three variants of terms of the first floating ice appearance until 2020 were computed in accordance with the basic climatic scenarios. It was shown that changes in the climatologic norms are significant for all the scenarios. In comparison with the present values, future changes in the norms can reach 5 through 15 days. 相似文献

The dynamics of energetic electrons (E e =0.17–8 MeV) and protons (E p =1 MeV) of the outer radiation belt during the magnetic storm of May 15, 2005, at high (GOES-10 and LANL-84 geosynchronous satellites) and low (Meteor-3M polar satellite) altitudes is analyzed. The data have been compared to the density, plasma velocity, solar wind, and magnetic field measurements on the ACE satellite and geomagnetic disturbances. During the magnetic storm main phase, the nighttime boundary of the region of trapped radiation and the center of westward electrojet shifted to L ~ 3. Enhancements of only low-energy electrons were observed on May 15, 2005. The belt of relativistic electrons with a maximum at L ~ 4 was formed during the substorm, the amplitude of which reached its maximum at ~0630 UT on May 16. The results are in good agreement with the regularity relating the position of a maximum of the new relativistic electron belt, boundaries of the trapped radiation region, and extreme low-latitude position of westward electrojet center to the Dst variation amplitude. 相似文献
