在有来复线的或其它的管壁皱纹的管中，由于引起副流，可能将非均质流转变为均质流。
To solve the problem that the present 2 - d temporal - spatial spectrum estimation algorithms are deteriorated when the number of signals become close to the dimension of the array , a kind of new signal model and approach for 2 - d temporal - spatial spectrum estimation is proposed
摘要针对现有空时二维谱估计算法在信号数增大时均不同程度出现性能上的恶化直至失致的问题，总结了目前通用的空时二维谱估计信号模型，提出了“时域副流形”的概念及相应的信号处理方法。
