The paper presents data on an original equipment complex, consisting of two apparatuses, designed to prepare rock and mineral samples for the isotopic analysis of their fluid and/or gas inclusions. An example of samples from the Guli alkaline ultramafic massif in the Maimecha–Kutui province, northern central Siberia, is employed to demonstrate the capabilities of the technique of stepwise sample crushing and multiple-isotope analysis of the fluid phase.  相似文献

Cosmic gamma-ray bursts detected in the RELEC experiment onboard the Vernov satellite     

A. V. Bogomolov  V. V. Bogomolov  A. F. Iyudin  E. A. Kuznetsova  P. Yu. Minaev  M. I. Panasyuk  A. S. Pozanenko  A. V. Prokhorov  S. I. Svertilov  A. M. Chernenko 《Astronomy Letters》2017,43(8):516-528

The RELEC scientific instrumentation onboard the Vernov spacecraft launched on July 8, 2014, included the DRGE gamma-ray and electron spectrometer. This instrument incorporates a set of scintillation phoswich detectors, including four identical X-ray and gamma-ray detectors in the energy range from 10 keV to 3 MeV with a total area of ~500 cm² directed toward the nadir, and an electron spectrometer containing three mutually orthogonal detector units with a geometry factor of ~2 cm² sr, which is also sensitive to X-rays and gamma-rays. The goal of the space experiment with the DRGE instrument was to investigate phenomena with fast temporal variability, in particular, terrestrial gammaray flashes (TGFs) and magnetospheric electron precipitations. However, the detectors of the DRGE instrument could record cosmic gamma-ray bursts (GRBs) and allowed one not only to perform a detailed analysis of the gamma-ray variability but also to compare the time profiles with the measurements made by other instruments of the RELEC scientific instrumentation (the detectors of optical and ultraviolet flashes, the radio-frequency and low-frequency analyzers of electromagnetic field parameters). We present the results of our observations of cosmicGRB 141011A and GRB 141104A, compare the parameters obtained in the GBM/Fermi and KONUS–Wind experiments, and estimate the redshifts and E _iso for the sources of these GRBs. The detectability of GRBs and good agreement between the independent estimates of their parameters obtained in various experiments are important factors of the successful operation of similar detectors onboard the Lomonosov spacecraft.  相似文献

Long-term observations of the electric field vertical component in Lake Baikal (preliminary results)     

V. S. Shneer  S. P. Gaidash  I. L. Trofimov  S. M. Korotaev  T. V. Kuznetsova  L. B. Tsirulnic  A. I. Panfilov  N. M. Budnev  R. R. Mirgazov 《Izvestiya Physics of the Solid Earth》2007,43(4):331-335

A deep-water station is constructed for measuring the vertical component of the electric field on the surface-bottom base. A long-term experiment of measuring the vertical component in Lake Baikal is carried out. The measured signal fully reflects (due to the absence of the telluric component) variations in total flows in the range of periods from a few hours to tens of days. The coefficient of internal turbulent friction is estimated from the divergence between theoretical and experimental periods of the inertial flow. The detection of spectral maximums corresponding to variation periods of the hard component of solar radiation is the most important result of the present study. Possibly, this fact is direct evidence for the global electric circuit closure under suitable regional conditions.  相似文献

Variations of the concentrations of major ions and nutrients in surface water of Southern Yakutia at the industrial development of the territory     

A. P. Chevychelov  L. I. Kuznetsova 《Water Resources》2016,43(3):504-512

The article presents the results obtained in studying variations of the concentrations of ion composition, and nutrients in the surface waters of Southern Yakutia in the construction zone of the Amur–Yakutsk Railway Main Line, as well as in streams in the territory of the Neryungri Coal and Aldan Gold-Mining regions. In 2007–2012, the concentrations of major ions in the 15 examined watercourses varied mostly under the effect of natural conditions, while variations of the concentrations of major ions and nutrients in surface waters of the coal- and gold-mining regions, estimated for the past 30–40 years, were significant as the result of anthropogenic and technogenic impact. Variations of all examined chemical characteristics of water in the examined rivers did not go beyond their MACs introduced by SanPin.  相似文献
