The velocity field is taken to have a Gaussian statistics with zero mean and defined noise with finite time correlations. It is shown that the inertial-range scaling regimes are given by the existence of infrared stable fixed points of the corresponding renormalization group equations with some angle integrals. The analysis of integrals is given. The problem is solved numerically and borderline spatial dimension  below which the stability of the scaling regime is not present is found as a function of anisotropy parameters.</abstract><trans-abstract xml:lang="ru">Рассмотрено влияние сильной одноосевой маломасштабной анизотропии на стабильность скейлинговых режимов в инерционном интервале в модели пассивно адвектированого поперечного векторного поля несжимаемым турбулентным потоком с использованием полево-теоретической ренормгруппы. Предполагается, что поле скоростей имеет гауссовскую статистику с нулевым средним и с определённым шумом с конечными временными корреляциями. Показано, что скейлинговые режимы в инерционном интервале связаны с существованием стабильных инфракрасных неподвижных точек соответствующих уравнений ренормгруппы с определёнными угловыми интегралами. Приведён анализ интегралов. Задача решена численно и граничные значения пространственной размерности , ниже которых скейлинговый режим нестабилен, найдены как функции параметров анизотропии.</trans-abstract><kwd-group xml:lang="en"><kwd>anomalous scaling</kwd><kwd>passive advection</kwd><kwd>renormalization group</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>оптимальный скейлинг</kwd><kwd>пассивная адвенция</kwd><kwd>группа ренормировок</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Falkovich G., Gaw.edzki K., Vergassola M.
