不变的

This algorithm was realized by minimizing the invariant ellipsoid of the closed loop system. Some sufficient conditions dependent on the invariant set for the satisfaction of the time domain hard constraints were also derived.

在系统初始状态小于某个界的情况下，将性能输出的能量作为优化的性能指标，通过最小化系统的不变椭圆域来实现系统优化控制，同时得到依赖于该不变域的满足时域硬约束的充分条件。

In order to describe the random-like feature of chaotic signal, the statistical analysis method for discrete time chaos system is studied. A domain iterative algorithm for numerical estimation of the invariant probability distribution is presented, which is the foundation for the statistical analysis and processing of chaotic signal.

针对混沌系统的随机性特征，本文研究了离散时间混沌系统的统计分析方法，并给出了一种基于Frobenius-Perron算子的区间迭代算法用于混沌映射不变分布的数值求解，该方法在样本数较少时，仍可以获得不变分布的良好估计，为混沌信号进一步的统计分析和处理奠定了基础。

Sterility neither prohibits nor nullifies marriage, without prejudice to the prescript of can.

Because the raw material of insulated layer and fire resistance and the making tecknology are different form that of ordinary cable , so it can resistant combustion, explosion and withstand 840℃ high temperature about 60 minutes. It can't be combustion, ignition and is constant in the propery of electric conduct.

由于绝缘层和耐火层的材料、工艺与普通电缆不同，故在易燃、易爆、极寒场合能承受-250℃～840℃高低温持续60分钟不燃烧，不着火，不老化，且导电性能不变。

In chapter 3,we dig out two families of invariant quartic curves of a quadratic system.

第五章讨论向量场具有对称中心的二次系统，利用系统的不变双曲线及不变四次曲线，我们确定了一个对应极限环（1.1）分布的二维参数区域，其边界的构成为如下几种常见的极限环分枝：霍夫分析，庞加莱分枝，同宿分枝和异宿分枝。

With the structure of FNN turning more complex, the good approach or classification is hard to get because of redundancies and uncertainties caused by both large volume uncertain data and lack of prior knowledge. Based on high order spectral reduction for rulers, a new structure changed Fuzzy Neural Network is proposed.

针对先验知识不完备和不确定的情况下海量数据造成的冗余和互斥，模糊神经网络结构变得复杂化并不能很快逼近和分类输出对象的情况，提出了一种基于高阶谱完成规则约简的变结构模糊神经网络的模型。

In chapter 2. to two classes of specific systems in engineering, we make researches into stability with respect to their own invariant sets through the theoretic techniques of HDS. And then we bring forward sufficient conditions of uniform asymptotic stability and exponential stability with respect to their own invariant sets in the sense of Lyapunov.

第二章针对实际工程之中的两类具体系统用混合动态系统的理论方法对其关于不变集的稳定性进行了研究，提出了它们关于各自的不变集在Lyapunov意义下一致渐近稳定、指数稳定的充分条件。

Originally eat 150ML / day five times, from 3 months after I go to work, feeding on a problem, to the present or each 150ML, 4 months after the beginning of Garmisch powder, half spoon of rice cereal to tune, out to 3 / 4, also increases over egg yolk, as not interested in hindsight, she always seemed reluctant to eat, they cut into the 4 th day of milk, the volume of the same, plus 1 / 3 spoon of rice flour in milk, the still do not have to闹着eating, tongue is not white, the other what is good and can play love to laugh, to sleep or every two hours during the day we should sleep 23:30 after eating milk can sleep the next morning, 8:30, still do not seem hungry.

原先能吃150ML/每日五次，从3个月我上班后，吃奶就成问题，到现在还是每次150ML，4个月时开始加米粉，半调羹米粉调的米糊能，吐出去3/4，也加过蛋黄，一样没兴趣，后来看她吃饭总是显得不情愿，就减成一日4次奶，量不变，加1/3调羹米粉在奶里，还是不闹着要吃，舌苔不白，其他什么都很好，能玩爱笑，睡觉也好，白天隔2小时就要睡一觉，晚上11点30分吃完奶能睡到第二天早上8点30分，还是不显得饿。

Treatment methods:(1) ink rollers problem deink, charged more rare.

XRD indicated that the replacement of the terephthalate anion by the polytungstate anion had little effect on the structure.

结果表明，经过同多钨酸根阴离子的交换以后，垂直于水滑石层板方向的平行层板方向的晶格参数值变小，平行层板方向的晶格参数值不变，(003)、(006)、(009)衍射峰处的层间距值比为3：2：1；交换过程没有改变水滑石的结构，水滑石原位生长在γ-Al2O3表面及内孔，比表面积由γ-Al2O3载体的219m2/g增加到247m2/g，孔径分布则由原来的2～11nm变化为3～4nm。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
