剖析了这些轨道的邻域的轨线结构，还考虑了经过Poisson稳定点及几乎周期点的横截圈和相应的回归映射，其中本文讨论了可定向闭曲面上具有伪轨跟踪性质的C〓-流，得到了可定向闭曲面上C〓-流具有伪轨跟踪性质的较为简洁的充分必要条件；最后本文借助于从可定向的闭曲面到不可定向闭曲面的复叠投射，讨论了不可定向闭曲面上的C〓-流与其提升的轨线之间的联系，解决了不可定向闭曲面上C〓-流具有伪轨跟踪性质的判定问题。

The number of desired signals is detected by using singular value decomposition. And the array input is transformed into the signal subspace. Orthogonality is derived for the weight vectors in multiple beamforming on this subspace. According to which, an orthogonal constant modulus algorithm is proposed by introducing the orthonormalization procedure into the static least square constant modulus algorithm.
