For an oscillating process z(t) (z(0)=2,t0), which is defined with the help of two homogeneous processes 1(t) and 2(t) with independent increments and nondegemerate Wiener components, under certain restrictions we establish a relation of the form and find the characteristic function of the ergodic distribution of the process considered.Translated from Ukrainskii Matematicheskii Zhurnal, Vol. 42, No. 10, pp. 1415–1421, October, 1990. 相似文献

A number of new 1,3-diaryl-4,7-phenanthrolines were synthesized by heterocyclization of arylidene-6-quinolylamines with acetophenones in the presence of an acidic catalyst. Intermediate amino ketones and side products, viz., N-(R1-benzyl)-6-quinolylamines and ,-unsaturated ketones, were isolated. The IR, UV, PMR, and mass spectra of the synthesized compounds are discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1398–1401, October, 1985. 相似文献

Previously unknown 2-methoxy(or ethoxy)-4-(11-oxo-9-phenyl-7,8,9,10,11,12-hexahydrobenzo[b][4,7]phenanthrolin-12-yl)phenyl esters of carboxylic acids were prepared by ternary condensation of vanillin or vanillal alkanoates with 6-quinolylamine and Phenidone. According to the 1H NMR spectra, the target products are formed as mixtures of diastereomers. 相似文献

The reaction of arylidene-2-naphthylamines with the ethyl ester of (2-quinolyl)--oxopropionic acid results in the synthesis of ethyl esters of 1-(2-quinolyl)-3-arylbenzo[f]quinoline-2-carboxylic acids. All the theoretically possible intermediate reaction products were isolated: the amino esters of 2-quinoline--oxopropionic acid, the hydroxy esters of tetrahydro- and esters of dihydrobenzo[f]quinoline-2-carboxylic acid, as well as the by-products — the ethyl ester of 2-quinolyl--(R-benzylidene)--oxopropionic acid. The IR, UV, and mass spectra of the synthesized compounds are discussed.Institute of Physical Organic Chemistry, Belorussian Academy of Sciences, Minsk 220603.

New 12-aryl(or hetaryl)-9-methyl(or 4-butoxyphenyl)-8,9,10,12-tetrahydro-7H-benzo[a]acridin-11-ones possessing two asymmetric carbon atoms (C9 and C12) were synthesized by condensation of 5-methyl-or 5-(4-butoxyphenyl)cyclohexane-1,3-dione with 2-naphthylamine and aromatic or heteroaromatic aldehydes. According to the 1H NMR data, the products were isolated as mixtures of diastereoisomers. 相似文献

Condensation of fluorosubstituted benzaldehydes with 2-naphthyl or 6-quinolylamine and cyclic β-diketones (,3-cyclohexanedione, dimedone, and 1,3-indandione) provided new fluoroderivatives of benzo[a]-acridine, 4,7-phenanthroline, and benzo[f]indeno[1,2-b]quinoline. Forming in the course of the reaction fluorophenylmethylene-2-naphthyl-(or 6-quinolyl)amines, arylbis(cyclohexane-1,3-dion-2-yl)methanes, and 2-(fluorophenylmethylene)-1,3-indandiones were isolated. 相似文献

The spectral densities of the time fluctuations of the amplitude of steady-state generation at two wavelengths 1=0.63 and 2=1.15 under conditions of turbulent fluctuations of the refractive index in the waveguide channel of an open optical resonator are studied. The frequency dependences of the spectral densities are analyzed at various states of atmospheric turbulence, including the state produced in an aerodynamic chamber. For wavelength 2 the fluctuations of the water-vapor content form a random absorption field. The distinctive features of the frequency dependence of the spectral density are discussed and related to the time cross-correlation of random fields of the passive impurity of the water-vapor concentration, the temperature, and the turbulent velocity of the flow. The asymptotic behavior of the frequency dependences of the spectral density is analyzed from the standpoint of the self-similarity of the stochastic characteristics of the system consisting of the waveguide channel and the medium.Odessa Hydrometeorological Institute.

The cross sections for the spallation of the heavy-metal nuclei 181Ta, 197Au, 207Pb, 209Bi, 232Th, and 238U induced by relativistic deuterons with energies of 2, 2.94, and 3.5 GeV per nucleon are measured using the deuteron beam from the Nuclotron accelerator of the JINR Laboratory of High Energy Physics in Dubna, Russia. The cross-section measurements employ a combined experimental technique involving the solidstate nuclear-track detectors and the activation gamma spectrometry. Adding our measurements to the database of experimental nuclear data will make it possible to test the computer codes used for selecting the parameters of the ADS-type facilities. 相似文献
