Here the constraint is given by nonlinear equalities and inequalities.

该约束条件是由非线性等式和不等式给出。

The dual equalities of intersections and additions of the finite subspaces in the Euclidan space V are also given.

给出欧氏空间V的有限个子空间的交与和的关于子空间正交补的对偶等式；

Ad looked rather pretty, for the sun had just set in splendor, and the equalities of rent were drowned in a saffron afterglow.

但此时整条路看起来都挺美，金灿灿的太阳刚落下山，橙红色的余辉掩盖了房屋的种种差异。
