Compared with the existing ones, the new criteria relax the limitation on coefficient matrix and give larger stable parameter domains.

与已有结果比较，新判据减弱了对系数矩阵的限制，扩大了稳定参数域。

However it was unable to find a stable parameter set when using the real catchment data with large range of upper and lower boundary values.

然而，在用到现实中的流域数据的时候，由于数据的上下边界差距很大，很难找出一套稳定的参数。

The proposed analysis method can easily determine the effect of system parameter perturbations on its stability and dynamic behaviour, and find out the stable parameter regions.

该方法比较容易找出参数摄动对系统稳定性及其性能指标的影响，并且可以找出参数的稳定域来。
