Autor: L. I. Grechikhin, D. A. Saharuk, A. B. Sivashko, A. A. Tsanava
Publikováno v: Izvestiâ Vysših Učebnyh Zavedenij i Ènergetičeskih ob Edinennij SNG. Ènergetika, Vol 0, Iss 4, Pp 59-68 (2010)
A windmill theory as an open power system is resolved in the paper. The paper presents a mechanism of a frontal resistance and a thrust load of the operating windmill which is based on occurrence of an active environmental component and formulates th

Silicon-nitride-based nanoceramic materials
Autor: E. S. Golubtsova, L. I. Grechikhin
Publikováno v: Inorganic Materials. 41:140-147
Based on the principle of maximum bond energy, a structural model is proposed for Si3N4 + 60 wt % MoSi2 + 5 wt % Y2O3 + 1.5 wt % Al2O3 ceramics. In this model, Si3N4 clusters form a star-like structure with columnar pores 0.45 and 1.5 nm in size. The

Using the broadening and shifts of the spectral lines of cesium for determining the concentrations of charged particles and neutral atoms in a dc arc plasma
Autor: L. I. Grechikhin, D. K. Skutov
Publikováno v: Journal of Applied Spectroscopy. 4:279-284
Experimental contours of several of the spectral lines of the cesium atom were obtained and the concentrations of charged particles and neutral atoms in a dc arc plasma were calculated. The Stark constants were computed precisely and the limiting cha

Determining the charged particle concentration in a dc arc from the emission spectrum of sodium
Autor: E. S. Tyunina, L. I. Grechikhin
Publikováno v: Journal of Applied Spectroscopy. 5:319-327
Several methods of measuring charged particle concentrations from the emission spectrum of sodium are discussed. The limits of applicability of each method are specified. Discrepancies in charged particle concentrations measured on the basis of the b

Error in the determination of charged-particle density in an inhomogeneous plasma source on the basis of spectral-line broadening
Autor: V. V. Voinov, L. I. Grechikhin
Publikováno v: Soviet Physics Journal. 12:1309-1312
The charged-particle density found from the Stark broadening of spectral lines in an inhomogeneous plasma source can be attributed with an error of 10–15% to regions of maximum spectral brightness of the line center. If the contour is recorded unde
