- ДокументРезультаты сравнения разработанной теоретической модели нижней части области F ионосферы с эмпирической моделью А. Д. Данилова(НТУ "ХПИ", 2004) Живолуп, Т. Г.Comparison of the elaborated theoretical model of the ionosphere F-region lower part with the A. D. Danilov empirical model is considered. Comparison results of the experimental and theoretical height profiles give evidence about good accuracy characteristics of the elaborated theoretical model
- ДокументОбоснование характеристик радара для определения скорости дрейфа ионосферной плазмы методом некогерентного рассеяния(НТУ "ХПИ", 2004) Емельянов, Л. Я.The aspects of ensuring of reliable ionospheric plasma drift velocity measurements by incoherent scatter method are considered. The substantiation of some parameters of IS radar is presente
- ДокументГафний - перспективный материал для ядерной энергетики(НТУ "ХПИ", 2004) Ефимов, Александр Вячеславович; Ажажа, В. М.; Пилипенко, Н. Н.; Мухачев, А. П.The basic nuclear-physical properties of hafnium as perspective absorber material for regulatory authority of nuclear reactors are considered. Fluoride calcium thermal technology of obtaining of high pure hafnium, which mastered in Ukraine is analyzed. The basic physical-mechanical properties and chemical composition of not imported hafnium in comparison with metal of foreign production are represented. With the purpose of improvement of the quality of metal was offered and carry out the complex of researches on advancing metallurgical processes of obtaining high pure hafnium and its deformation processing
- ДокументУниверсальный измерительный блок для изучения трех фотоэффектов на монохроматоре УМ-2(НТУ "ХПИ", 2004) Ушаков, В. В.; Корж, Ирина АнатолиевнаBy way of extending of functional mobility and didactic capacity of educational equipment the laboratory device based on monochromator УМ-2 for learning three kinds of photoeffect - external (with vacuume phototube, or photoelectronic multiplyer), internal(with photoresistor) and ventil (with photodiode) is actualized. Alternation brings to effect by adequate commutation of apparatus and elements on the stand. Computation of the optimal duty of ventil photoelement and Plane constant is realized on PC
- ДокументРегистрация показаний спектрофотометра СФ-46 с использованием ЭВМ(НТУ "ХПИ", 2004) Шкалето, Владимир Иванович; Копач, Галина Ивановна; Харченко, Н. М.; Карасёв, С. Н.The circuit of the interface unit of a computer with a spectrophotometer СФ-46, using the universal voltmeter B7-23 is described. The device is intended to automatic registration results of measurement spectral dependencies of a transmittance
