* * *А не -- rather than; other than; instead of; not, and not; but not; versus; vis-a-visIn this case the process probably involves fatigue rather than abrasion.However, in practice, the measured strains are in a numerical form other than a smooth function.The partial dislocations are separated by stacking-fault, instead of an antiphase boundary.The choice of a finite difference technique ( versus finite element) provides some advantage in this way.Thus the nickel-base superalloys become creep limited by local crack initiation and not total rupture.Thus the Young modulus not annealed surface hardness was definitely shown to be the controlling parameter.The distorted signal is judged to be the result of limitation of the capacitance measuring system, vis-a-vis film rupture.Русско-английский научно-технический словарь переводчика > а не

1) Two or more compounds having the same molecular formula, but a different arrangement of atoms within the molecule. 2) One of two or more chemical substances having the same elementary percentage composition and molecular weight but differing in structure, and therefore in properties; there are many ways in which such structural differences occur.

polychlorinated biphenyl
PCBs are a family of chemical compounds which do not exist in nature but which are man-made. Commercial mixtures are clear, pale yellow liquids, manufactured by the replacement of hydrogen atoms on the biphenyl molecule by chlorine. Because of their physical properties, PCBs are commonly found in electrical equipment which requires dielectric fluid such as power transformers and capacitors, as well as in hydraulic machinery, vacuum pumps, compressors and heat-exchanger fluids. Other uses include: lubricants, fluorescent light ballasts, paints, glues, waxes, carbonless copy paper, inks including newspapers, dust-control agents for dirt roads, solvents for spreading insecticides, cutting oils. PCBs are stable compounds and although they are no longer manufactured they are extremely persistent and remain in huge quantities in the atmosphere and in landfill sites. They are not water-soluble and float on the surface of water where they are eaten by aquatic animals and so enter the food chain. PCBs are fat-soluble, and are therefore easy to take into the system, but difficult to excrete. (Source: PZ / PHC)
