Goodness; moral excellence; good quality 美德;德性;优点 Virtue carried to extremes can turn into vice; humility, for example, can degenerate into servility and spinelessness.

We study the attractive manifold method of the iterative learning control for a class of degenerate systems in the chapter Ⅲ. When the learning control systems don't satisfy the convergence condition, we present the learning control method satisfying the condition by constructing a stable and attractive manifold corresponding system. This method makes the system with better robustness.

第三章主要研究了一类退化系统目标跟踪的迭代学习控制的吸引流形方法，在系统不满足一般收敛条件的情况下，我们通过构造一个相应于所给系统稳定而吸引的流形，导出所满足要求的迭代学习控制，该方法对系统有较好的鲁棒性。

If sterility is due to the body, then the body is degenerate and wrong

如果不能生育是由于身体上的关系，那么，那个身体是退化的，是错误的

In addition, the nonlinear processes such as cross-phase modulation, non-degenerate two-photon absorption, and stimulated Raman scattering must also be considered for double wavelengths propagating in waveguide.

在归纳分析了SOI对光信号处理的研究进展的基础上，进一步完善了超快脉冲在脊形硅波导中演变时所满足的线性和非线性传输方程，在此非线性方程中包括波导线性损耗、群速度色散和三阶色散等线性效应；同时也包含了自相位调制、简并双光子吸收、自由载流子吸收和自由载流子色散等非线性过程；当双光场在波导中传输时，脉冲之间的交叉相位调制、非简并双光子吸收和受激拉曼散射效应等非线性效应也被考虑。

Anaerobic synecology of the hydrogen-producing fermentation system was investigated under certain test condition in this thesis. In the continuous flow system of anaerobic hydrogen-producing fermentation, the succession of hydrogen-producing acidogenic microbiology may be regressive process. By regressive process we means that the original community getting from nature which structure being complex with a high ability would degenerate gently to a certain climax community which structure being simple with less ability.
