dc.description.abstract Most important feature of greenhouse films is their resistance to ultraviolet radiation. The electronic spectra of the modified films were studied. Qualitative spectra were obtained for polyethylene films with a thickness of 75-80 microns. A mathematical model, that allows one to calculate the film with a given transparency in the UV range without costly extrusions, was developed and tested. It is shown, that for the design of a film with given thickness and transparency, is sufficient the presence of spectrum of the greenhouse-film, containing identical filtering additives. en_US
dc.description.abstract Calitatea importantă a peliculei pentru sere este rezistenţa acesteia faţa de razele UV. Au fost cercetate spectrele electronice ale peliculelor modificate. Spectrele calitative au fost obţinute pentru pelicule cu grosimea 75-80 microni. A fost elaborat un model matematic, care permite proiectarea peliculei cu valorile prestabilite ale grosimii şi transparenţei în domeniul UV, evitând producerea costisitoare a partidelor mici de probă. S-a stabilit, că pentru proiectarea peliculei noi va fi suficient un spectru al peliculei cu aceleaşi aditive UV-protectoare. ro
dc.description.abstract La propriété la plus importante de la filme de serre est sa stabilité vers les rayons UV. Les spectres électroniques des filmes modifiées ont été étudiés. Les meilleurs spectres ont été obtenus pour des films d'une épaisseur de 75-80 microns. Un modèle mathématique, qui permet de concevoir des films avec des valeurs prédéterminés de l'épaisseur et de la transparence dans l'UV, et qui permet d'éviter la production coûteux des échantillons, a été développé et évalué. Il est montré, que pour la conception des nouvelles films avec de l’épaisseur et de la transparence donné, serra suffisant un seul spectre de film, contenant le mêmes aditifs UVfiltrant. fr
dc.description.abstract Важнейшим свойством тепличной плёнки является её устойчивость к УФ-излучению. Исследовались электронные спектры модифицированных плёнок. Лучшие по качеству спектры получены для полиэтиленовых пленок толщиной 75-80 микрон. Была разработана и проверена математическая модель, позволяющая рассчитать плёнку с заданной прозрачностью в УФ диапазоне без проведения дорогостоящих пробных экструзий. Показано, что для проектирования плёнки заданной толщины и прозрачности достаточно наличие одного спектра плёнки, содержащей ту же УФ-фильтрующую добавку. ru
