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.

本文首先分别概述非线性系统的控制与人工神经网络在控制中的应用；然后研究非线性系统各种可逆性的定义、数学描述及可逆性条件，并用于分析逆系统控制方法的可行性，得出有关逆系统控制方法可行性的结论，阐明一般情况下α阶逆系统才工程可实现；接着本文针对一般单输入单输出连续、离散非线性系统，研究神经网络α阶逆系统的可行性、结构与辨识以及基于神经网络α阶逆系统的各种复合控制方法，并给出应用例子；最后本文结合实际项目，针对采用可控串补的电力系统，设计神经网络α阶逆系统控制方法，研究其对提高电力系统稳定性的作用。

This third quarter Moon and first quarter Moon were both photographed during the last lunar cycle or lunation with the same telescope and camera.

It is not easy to do IDC company to hold out, because investment is larger, intermediary enlighten elegant development arrives today, itself took not little roundabout way, I and introduced from the northern and western nationalities or from abroad Xiang Feng are mention in inn of a chaffy dish build intermediary enlighten elegant, at that time IDC company of home is not very much, the business is so better also do, but competition is intense later, gain is small also, at first intermediary enlighten elegant business and technology are us almost two people do together, be asleep in the computer room mistily is constant some thing, busy to before dawn it is 34 bits often thing, but also be at long last one step by step came over, calculate so now, the development of the company there supports very much all the time in him heart, although I had been absent now intermediary enlighten elegant such also.

做IDC公司挺不轻易的，因为投资比较大，媒迪雅发展到今天，本身走了不少的弯路，我和胡向锋是在一个火锅店里谈起建立媒迪雅的，那个时候国内的IDC公司并不是很多，所以生意也比较好做，但是后来竞争激烈了，利润也就低了，起初媒迪雅的业务和技术几乎都是我们两个人一起做的，模模糊糊在机房里睡着是常有的事情，忙到凌晨三四点是经常的事情，但总算也是一步步的过来了，所以就算到现在，自己心里一直很支持那边公司的发展，虽然现在我已经不在媒迪雅也如此。

We want to know whether this is the last of our current nuclear power plant projects, or just the first of another series.

我们想知道，这到底是我们现有核电厂计划中的最后一个，还是另一系列核电厂计划的第一个。

According to him, this involves not parti***ting in the first 20 percent or the last 20 percent of an investment run-up.

罗斯公式是说，在某项投资的增值过程中，不要想赚前面的 20%，也不要想赚最后的 20%，最好是赚中间的 60%。

Like this piece de resistance , going from last May's days of rage to this Wednesday in May when Commissioner David Stern or one of his lieutenants will hand him his first MVP trophy.

In the UK, Google is only the second quarter of receivables or 29 percent, less than 39% of the first quarter and fourth quarter of last year's 44 percent.

在英国，谷歌第二季度应收涨幅仅为29%，低于第一季度的39%和去年第四季度的44%。

I have been reefing for the last 10 years but this is my first nano reef. Initially, in setting up a 24gallon tank I had low expectations. I wasn't sure if keeping colorful SPS would be easy or at all possible with a small volume of water that fluctuates parameters very easily. I decided to try it anyway.

我已经有10年饲养珊瑚的经验，但是从来没有试过微缸，这是我第一个微缸，我在设立这个96L的微缸时，我对它就没有多大的期望，我不能确定SPS能否在这么小的一个空间里面生存，因为微缸的水量太少，各种元素和指标都很容易发生震荡。

Information safety is not only the information network safety of a business or an individual,but also the first priority of the nation's safety and social stability.Under such environment,it seems to be the last chance for the domestic businesses of information safety service industry to catch up with the foreign counterparts in the new IT times.

国家依靠自己的力量发展自己的信息安全产业，意味着国家在资金、政策、税收等方面的扶植力度将会加大，意味着虽然我们的信息安全产业相对国外起步较晚，但国内企业具有非常高的胜算机会，而不会像以往的IT业一样，不得不被国际社会几大巨头牵着鼻子走！

When I wrote an essay in 1995 on prematurity in science﹝O.W. Sacks, Scotoma: Forgetting and Neglect in Science, Ed. R. B. Silver (New York: New York Review of Books, 1996), 141-187﹞, I cited among many other examples, the failure to comprehend or see the relevance of gradiential theory when it was published; Luria himself found it incomprehensible in 1969, when Glodberg first presented it to him. But there has been a great change, a paradigm shift in the last decade, partly connected with theories of global brain function such as Gerald Edelman's partly with the development of neural nets as modelling systems massively parallel computer systems, and the like, and the concept of cerebral gradients-Glodberg's vision as a student-is now much more widely accepted.

1995年，当我著手撰写一篇有关科学的未成熟性的论文，我援引许多例子来说明当气候未成熟时，许多先知是被忽略了，在其中，我引用了高德伯的递变理论。1969年，高德伯第一次提出这个理论时，他的指导教授卢瑞亚认为是不可能的，但是过去十年来，研究的典范改变了(paradigm shift，如库恩Kuhn所说的)，这个改变一部分是因为艾德曼等人的宏观大脑功能理论的提出，部分则是因为神经网路的发展(例如类神经网路模式、平行处理系统)，还有一部分原因是高德伯的大脑递变理论已逐渐被接受。
