At first, this paper surveys nonlinear control and the applications of neural networks in control respectively. Then it studies definitions, mathematical descriptions and conditions of invertibility for nonlinear systems, which are used to analyze the feasibility of inverse system control method. Conclusions about the feasibility of inverse control and the realizability of αth-order inverse systems in engineering are achieved. Furthermore, this paper discusses the feasibility, structure and identification of neural network αth-order inverse system for general single-input single-output continuous or discrete nonlinear systems and various composite control methods based on the αth-order inverse. At last, as a part work of an actual project, this paper focuses on the design of neural network αth-order inverse control method for thyristor controlled series compensation in power systems and its effect in improving the stability of power systems.

In t he conclusion part, the paper makes a further analysis of Umberto Eco's rational reflection about the spirit of the times, combining his point of view about the reason, order and Postmodernism to points out that he is able to discard the world significance while sticking to a new one, able to reconstruct the new order while breaking it, able to take part in the game but not Addict to its joyance— that's Umberto Eco, the hero Theseus in modern world, who explores the labyrinth just like a fish swimming in the sea.

On the net collect summed up the following respects, offer text to receive the main page on the site repeatedly, according to website size, more or less can webpage numerary receive all pages repeatedly even; For every join provides a brief introduction, in order to hints this one's duty allows the person that visit is about which on one hand; Exceed in website map and text the mainest crucial term alludes inside join, the help searchs theme of page of join of engine identifying place is about which on one hand; Help engine indexes a few dynamic pages, because a few pages will be of dynamic generation, if not be user behavior is called,will not show come, can put this join on website map, in order to help the dynamic page with engine main index; To make website map attracts the visit of network spider, the descriptive sex statement with go up certain must be written to use this connective keyword to have simple description at the back of join, but the use keyword that cannot transfer, can be just the opposite to what one wished otherwise; Because general spider catchs page of before 3 class only, so website map makes the same score better more, what point to here is logical way, is not physical method.

在网上搜集总结了以下几个方面，提供文本连接到站点上主要的页面，根据网站大小，网页数目的多少甚至可以连接到所有的页面；为每个连接提供一个简短的介绍，用以提示访问者这部分内容是关于哪一方面的；在网站地图和文本超连接里面提及最主要的要害词语，帮助搜索引擎识别所连接页面主题是关于哪一方面的；帮助引擎索引一些动态页面，由于一些页面将是动态产生的，假如不是用户行为调用将不会显示出来，可以将此连接放在网站地图上，以帮助引擎索引重要的动态页面；为了使网站地图吸引网络蜘蛛的访问，一定要在连接后面写上一定的描述性语句并使用此连接的要害词进行简单描述，但不能过渡的使用要害词，否则会适得其反；因为一般蜘蛛只抓前三级页面，所以网站地图越平越好，这里指的是逻辑路径，而不是物理路径。

In order to make us well know about Outer Mongolia and this period of history, the paper attempts to expatiate the sight of the actor about the independence of Outer Mongolia from the aspects of the process of its independence, experiences of the history and the impacts to China. I try to volunteer to give an opinion in order to let others with wonderful ideas follow it .

Comparison with the classical fourth-order LWC scheme shows that the NAD-type methods have many advantages. They can generate clearer snapshots of wave fields without any visible dispersion. To obtain the results without any numerical dispersion, the time cost by the LWC schemes is about 559, 1222 and 1955 times of that taken by ONADM, RNADM and SNADM, receptively. Besides, the storage space of ONADM is roughly about 3.3% of that needed for the fourth-order LWC scheme, while of RNADM and SNADM is about 5.8‰.

So we adopted the isotope marking method in order to know the distribution of BBP in male and female mice. The result indicated 〓H-BBP presented the first-order kinetics and matched the open two-compartment model. Distributional half-life was about 20 minutes and eliminable half-life was about 6-7 hours. As α(the speed constant of distributional phase) was about ten times β(the speed constant of eliminable phase), this compound had a fast distribution and a low elimination.

On the basis of systematically reviewing relevant theory and practice about social order and its construction, this paper thoroughly investigates the systematic inspirations of HEXIE Management Theory to the developing theme of establishing and forming harmonious society order, and the value of this theory. With a view of systems engineering and by using HEXIE Management Theory as an instructing idea and analyzing tool, this paper systematically constructs the forming mechanism of harmonious society order from three aspects:(1) the optimization and improvement of government's designing and planning function,(2) the independent evolution of social system under environmental inducement, and (3) the organic coupling between the forementioned two aspects surrounding developing theme. This paper finally gets a HEXIE-Management-Theory-based realization way of the anticipated man-made order, the evolved increscent order and finally the complete order in harmonious society.

In the night, we often carried a flashlight and a bag to the stream in front of the house to catch frogs. Once, in order to give nutrition to my auntie who was then in the family way, I, together with my uncle, went along the stream for nearly two kilometers in order to catch more frogs. I was about to catch a big one crouching at a rock when a meter-long poisonous snake came into my vision. The snake was also attempting at the frog. It frightened me and my uncle greatly. However, panic was only our punishment. The snake went away and the frog escaped. Nevertheless, we got a bumper harvest that night. We caught about thirty frogs altogether, more than 5 kilograms.

到晚上打着手电、提一只布口袋，下到屋前的小溪里捉青蛙：一次为了给月子里的孃孃补补身体，我领着叔叔顺着小溪走了近两公里，捉青蛙捉得兴起，当我正想伸手去逮蹲在石头上的一只肥大的青蛙时，突然发现旁边一条一米多长的毒蛇吐着红舌头也伺机扑向这只大青蛙，着实把我和叔叔吓出了一身冷汗，好在有惊无险，毒蛇遛了，大青蛙也跑了，不过，那天夜里收获颇丰，共捉到三十多只青蛙，足有十余斤。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
