研究表明，在高阶色散下，正负五阶非线性的存在仍然分别对交叉相位调制不稳定性起加强和削弱的作用；

The results show that, in case of high-order dispersion, the positive and negative quintic nonlinearity also intensifies and weakens the cross-phase modulation instability, respectively.

工业锅炉的主要动态特性包括非线性、非最小相位特征、不稳定性、时滞和负荷干扰，采用传统控制方法难以实施有效控制。

The major dynamics of a boiler include non-linearity, non-minimum phase behavior, instability, delay and load disturbance. The traditional control strategy could not offer satisfactory result.
