This dissertation also applies the above method on phase-locked loops design by frequency domain approach for a perturbed PLL system.

以上提出之方法更进一步延伸至具有扰动参数的锁相回路系统的设计分析。

Symbolic Dynamics has the advantage of being simple and to the point, can be used to analyze the essence of chaos-happening in the energy system; Melnicov Method can be used to study the mechanism of chaos-happening after system was perturbed. Chapter thirteen briefly introduced how to use the two methods to study chaos in a life energy system.

符号动力学以其简单和"粗粒化"的优点，抓住了能量系统中混沌发生的本质规律进行分析，而梅尔尼科夫方法则专门研究能量系统在受到扰动后产生混沌的机制，本文简要介绍了如何运用两种方法研究生命能量系统中的混沌并例举了简短的实例。

This paper shall attempt to look at some aspects of controller synthesis for the multivariable servomechanism problem when the plant to be controlled is subject to uncertainty-in this case,a controller is to be found so that satisfactory regulation/tracking occurs in spite of the fact that the parameters of the plant may be allowed to vary,subject only to the condition that the resultant perturbed system remains stable.

例7 本篇将致力于探讨在待检对象受到不确定性的影响，而仅仅服从受扰动的系统最终保持稳定，这一条件之情况下的多变量随动系统中控制器综合的某些方面的问题。在这种场合，尽管受控对象的参数允许发生变化，而控制器必须具有令人满意的调节和跟随性能。

Given this assumption, even if the parameters of the system are randomly perturbed, by either genetic mutation, environmental variance or experimental manipulation during development, the system will generate a limited and discrete subset of phenotypes.

而在这种假设的前提下，即使系统各参数值在发育过程中受到随机的扰动（或者是遗传突变，或者是环境变化或人工实验操纵），系统也会产生出某个有限的、离散的表型[11]子集。

Given this assumption, even if the parameters of the system are randomly perturbed, by either genetic mutation, environmental variance or experimental manipulation during development, the system will generate a limited and discrete subset of phenotypes. Thus the realm of possible forms is a property of the internal structure of the system.

而在这种假设的前提下，即使系统各参数值受到发育过程中的随机扰动（或者是遗传突变，或者是环境变化或人工实验操纵），系统会产生出某个某个有限的、离散的表型[11]子集，因此，生物可能形态的王国，其疆域从属于生命系统的内在结构。

First, for state estimation problem of the linear stochastic systems with uncertainties in both the state matrix and the noise matrix, a new satisfactory estimator is constructed with stochastic theory, which can guarantee that estimator error system with bounded perturbed model parameter satisfies the constraint indexes that is given. Thus a sufficient condition of solving satisfactory estimation is obtained; secondly, the algorithm of designing satisfactory estimator is presented by analysis.

首先，根据满意控制思想，针对一类在状态矩阵及噪声矩阵中均含有不确定性的随机系统，设计一种满意估计器，使预测误差系统在模型的参数发生扰动时，依然满足预先给定的设计约束指标，得到了满意估计问题求解的充分条件；然后根据分析给出了满意估计器设计的算法。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
