采用非正交坐标系可不用考虑电磁场的分解与叠加，减少网格数量，使理论研究方便快捷。
Using nonorthogonal coordinates system can avoid the decomposition and composition of electromagnetic field, and reduces the quantity of grids.
该方法的另一个重要特点是分解所得各本征模态函数及非模态函数是严格正交的，不会产生模态混淆。
Another merit is that IMFs and non-IMFs decomposed by the method are orthogonal each other and can prevent IMFs from mode confusing.
