orthogonality relation的用法和样例：
例句
- The paper gives explanations for such orthogonal relation, in which the vector interior product explanation is very useful.
文中给出了这种正交关系的几何解释，其中的矢量内积解释是很有用的。 - The orthogonality relationship is applied to the treatment of boundary conditions to decouple the coefficient equations, and the explicit solutions are obtained.
并将正交关系应用于可对角化边界条件的处理，实现了求解待定系数方程组的解耦，求得问题的显式封闭解。
