得到量的阶数，其中是一类具有混合导数的函数，或相应的预极限差分，有界于。在此过程中，得到了一些独立有趣的结果：Hardy-Littlewood定理的一个推广，以及最佳项三角逼近的阶数。参考书目：16篇。
The orders of the quantities are obtained, where is a class of functions with mixed derivative, or the corresponding prelimiting difference, bounded in . In the process some results of independent interest are obtained: a generalization of the Hardy-Littlewood theorem, and the orders of the best -term trigonometric approximations. Bibliography: 16 titles.
