   <abstract xml:lang="ru">
    <p>В работе описана модель и представлен вычислительный алгоритм восстановления рентгеновской составляющей спектра Солнца по данным измерений в каналах XL (0.1–0.8 нм) и XS (0.05–0.4 нм или 0.05–0.3 нм) спутников GOES и канала QD (0.1–7 нм) спутника SDO. В ее основу положен спектр излучения оптически тонкой плазмы в приближении Mewe, который является температурным спектром. В работе сделано предположение о возможности представления полного спектра в виде суперпозиции спектров Mewe, помещенных в поглощающую среду атмосферы Солнца на глубину, соответствующую оптической толщине, равной единице для энергии, отвечающей значению температурного параметра. Таким образом, модель представляет собой вариант мультитемпературного приближения. В Приложении даны аппроксимационные выражения для определения опорных функций, по которым вычисляются параметры спектра.</p>

    <p>Model and computational algorithm for recovering the X-ray component of the solar spectrum based on GOES XL (0.1–0.8 nm), XS (0.05–0.4 nm or 0.05–0.3 nm) and SDO QD (0.1–7 nm) channels data are presented. The model based the Mewe approximation of emission from optically thin plasmas that presents a temperature-like spectrum. The possibility to present the result spectrum as a superposition of Mewe spectrums placed in the solar absorbing atmosphere at one optical depth for its temperature parameter energy is suggested in this paper. So the model is a variation of the multi-temperature approximation. Spectrum parameters are determined on the basis of support functions, approximation expressions for which are given in appendix.</p>
