Study of ultraviolet spectrophotometer (λ = 200...400 nm) and its components

The ultraviolet spectrometer for the analysis of solid and liquid-phase objects is considered in this paper, and researches components of the device are performed as well. Cells for the study of liquid-phase objects in the ultraviolet region of the spectrum (λ = 200...400 nm) are selected, and their transmission spectra are obtained. The results of the calibration instrument wavelength scale by three characteristic lines are given. For calibration of the scale unit ultraviolet glass series UFS were investigated. Spectral characteristics of glasses UFS showed that the convergence of the experimental and calculated dependences of T(λ) is not worse than 0,05 %.

Keywords: spectrophotometer, polychromator, diffraction grating, cell, transmittance, Rowland circle.

Application of ring diffuser with a fairing as a transducer of gas flow

This paper shows the problem of application of the ring diffuser as a transducer of gas flow. This choice is due to the known characteristics of persistence and loss of any value of the relative length at different degrees of expansion for this device. In the paper, the characteristics of the discharge coefficient of flow meters for variable differential pressure expansion device of this type.

Keywords: flow meter, diffusor, flow rate, natural gas, quantity, accuracy.

Perspectives of power industry of Russia

The concept of increasing operational reliability of power industry of Russia step-by-step implementation the systems of precision measuring and computing predicting monitoring of technical condition and emergency protection generating and ancillary equipment at first on separate power plants, then – regional electrical power complexes and, at last, – National system of protection of power industry is offered.
The basis of a technical solution a problem is made developed in MSTU named after Bauman by embeddable phase-chronometric complexes.
This problem is typical for many developed countries, including in part by the United States, where the market reform of the national electricity industries has led to the widespread deterioration non-renewable equipment, including – and generating!
This problem is typical for many developed countries, including in part by the United States, where the market reform of the national electricity industries has led to the widespread deterioration non-renewable equipment, including – the generating!
So, only burst in the USA (the State of California, August 2003) the electrical power crisis which has entailed losses to 20 bln. dollars and the deficit of the electric power about 5-6 GW, forced the Administration of this country to enter the standards which are safely protecting national power industry from destructive market conversions.

Keywords: power industry, market, crisis, technical condition, forecast, accident, protection, phase-chronometry.

Modelling nanostructure of mediums tolstoys of films of passive devices of micromaking ups

In operation possibility of application of an analogue method of a small disturbing body for definition of differential performances of quasi-static (static) electric fields in nanosized mediums of thick-film resistors and electrical condensers of micromakingups is shown. Modelling nanostructure mediums of thick films of passive devices of micromakingups on the basis of boundary-value problems featured by means of the automodelling equation of Laplace is offered. It is revealed on a bottom предложеной theories of a method of a small disturbing body and the observational measurings that it is possible not only to calculate, but also to measure field builders by a frequency modulated expedient. The satisfactory consent of settlement and observational values is scored.

Keywords: an analogue method, modelling of physical fields, nanostructuremedium, a thick film, a disturbing body, differential performances, an electrodynamic field.
