KW - Lorentz space, Besov's class, approximation.
AB - <p style="text-align: justify;">In this paper, Lorentz space of functions of several variables and Besov&#39;s class are considered. We establish an exact approximation order of Besov&#39;s class by partial sums of Fourier&#39;s series for multiple trigonometric system.</p>
