Computer-aided surface analysis techniques

The application of computers to surface analysis instrumentation has greatly expanded the surface analyst's productivity. The fundamentals of how computers control and collect data from different types of surface sensitive spectrometers (and other parts of surface analysis instrumentation, such as the scan generator) will be discussed following brief explanations of the physics of several of the more widely used surface spectroscopies. Examples of ways in which the computer has allowed surface spectroscopies to evolve will be shown in the areas of peak intensity measurements, “smart” and rotational depth profiling, line profiling, characteristic peak transition imaging combined with picture processing, and automated peak identification.     

Controlled rational heating of objects for heat treatment

The article presents a method of solving the problem of controlled heating involving the reproduction of some regularity of heating the surface of an object. As an example the article presents the solution of the problem of controlled radiative heating of a steel cylinder, and the obtained calculation is compared with experimental data.Translated from Inzhenerno-fizicheskii Zhurnal, Vol. 61, No. 2, pp. 187–189, August, 1991.     

Improving the cohesion of nitron fibre

Conclusions It has been established that increase in cohesion of the fibres depends not only on the amount of sorbed latex but also on the character of the distribution of the latex particles on the surface of the fibre.Tashkent Textile and Light Industry Institute.

Fabrication and prospects for the development of polyester microfibres (review)

One of the promising trends in the development of textile fibres — the creation of technology and equipment for production of microfibres which makes it possible to obtain comfortable new materials was analyzed. The technological characteristics of fabrication of microfibres with two levels of filament linear density were examined: 0.1–0.03 tex by high-speed spinning (HSS) using special techniques, and 0.03–0.002 tex with sector structure based on two-component systems. The stable tendency toward development of new techniques for thinning filaments to create a new generation of textile materials was pointed out.All-Russian Scientific-Research Institute of Synthetic Fibres, Tver'.
