In order to eliminate the influence caused by the nonminimum phase characteristic of a common Boost DC／DC converter, Viswanathan K has proposed a novel tristate Boost DC／DC converter. For enhancing performance, the statespace averaging model of this converter was first presented in this paper. Due to the nonlinear nature in this model, an inputoutput feedback linearization technique was adopted, and a complete controllable linear system was obtained. Then a statefeedback control strategy was designed based on this linear system. Simulation results show that the proposed control strategy can assure constant output voltage in a wide range, so as to realize the stability of the system during large fluctuation of power supply and load disturbance. Good dynamic performance can also be achieved.

针对 Viswanathan K为消除普通BOOST DC／DC变换器的非最小相位特性而提出的三态Boost DC／DC变换器，为进一步提高这种电路拓扑的性能，在建立了变换器状态空间平均模型的基础上，针对其多变量、非线性特点，采用输入输出线性化将其转化为一个完全可控的线性系统，在此基础上应用现有成熟的线性控制策略进行了控制系统的设计，并且采用MATLAB进行仿真验证，结果表明：这种非线性控制策略可以确保输出电压在大范围内恒定可调，且即使存在大范围扰动(输入电压和负载变化均较大)的情况下，系统也可以确保稳定性和良好的动态性能。

It was in the cities that the elements that can be associated with modern capitalism first appeared--the use of money and commercial paper in place of barter, open competition in place of social deference and hierarchy, with an attendant rise in social disorder, and the appearance of factories using coal or water power in place of independent craftspeople working with hand tools.

正是在城市中首先出现了能够与现代资本主义相关联的因素—货币和商业票据的使用代替了实物交易；开放的竞争代替了社会顺从和等级制度，而随之而来的是社会秩序的紊乱；出现了以煤和水为动力的工厂，取代了利用手工工具的独立手工业者。

城市中，和现代资本主义关联的因素首先出现，他们是钱和贸易纸币的使用代替物物交换、伴随着一个社会混乱的上升，开放的竞争代替社会顺从和阶级、使用煤和水能源的工厂出现代替独立的手工艺人的手工工作。

In order to solve these problems encountered in the application of Artificial Intelligence in fault diagnosis of power transformer, some improved methods are presented, the main research work of this dissertation consists of the following parts: The conception of cumulative frequency in data reliability analysis is utilized to unify the results of Dissolved Gas Analysis. And with the application of the class-attribute function, the evaluation of typicality of samples and the selection of characteristic vectors of fault could be realized by integrating the technique of multivariate statistical analysis.

boiler is a important power equipment,the require is to provide qualified vapour,let the amount of vapour maked by boiler suit for the load.because of this,every main parameter in the process of the product should be strict controlled.this paper is introduced same main control system in the process of boiler control、concentrate and disperse control system 、the characteristic and the develop of the MCGS compose status software.integrate with the technique of the boiler, discuss the single momentum, double momentum, three momentum boiler control system distinguishly.we think in the process of micro boiler control, three momentum control is the best choice,and has been well implemented in the water level mediation.further more,use the concentrate and disperse control and MCGS compose statue sofeware can achieve the control of the boiler,and can reach a fine effect..

锅炉是一个重要的动力设备，其要求是供给合格的蒸汽，使锅炉发气量适合负荷的需要。为此，生产过程的各个主要参数必须严格控制。本设计了研究锅炉控制过程的几个主要控制系统，以及集散控制系统和MCGS组态软件的特点和发展状况。结合锅炉的工艺情况，针对单冲量、双冲量、三冲量锅炉控制系统，对它们存在的利弊做出了比较和分析。结合生产实践，对三冲量的算法进行比较，认为在小型锅炉控制过程中，三冲量控制是最好的选择，并在水位调节中得到很好的应用。

In the works of this genre, viewers may see the subject of a work commit suicide with a gun, be bogged down in a state of faithlessness, lawless and lost in bewildering reality and in the magnetic field of power; and in some corner along the street waiting for the expected as well as the unexpected appearance of 'you'. With one hundred bricks on his back, and luggage in hand, he heads to the railway station, leaving his hometown, fully loaded, for his unknown destiny - an experience we Chinese are most familiar with.

所以，在各种形式的作品中，观众会看到她在失落信仰、缺少权威、迷失于现实的年代，在权力磁场举枪自轰；会在街道某个角落等待意料之外，又在意料之内的你的出现；会看见他背上一百块板砖，手持行李，徒步走向火车站，背负重担离开原居城巿，藉此表达中国人最是熟悉不过的离乡背井，作者以简洁有力的方式与观众分享让人心生哀愁的"国情"……。

In the meantime, we also hope cadre of leaders of all levels can go in for sth in a large scale the wind of investigation and study, often thorough basic level, be good at discover and summing up people to play the new experience of creation in new condition, offer for us have the deal, manuscript that has depth, issue the power of command model at filling with benefit, encouragement and solidarity people devotes into the great cause at building socialism with Chinese feature actively.

Gonzalez, from France's Research Institute for Development, will be charged with guiding the CIRMF's 157 staff and US$5-million annual research budget. The centre, based in Franceville in southeast Gabon, boasts research infrastructure that is rare in Africa, including a biosafety level 4 lab for working with the world's most dangerous pathogens, and has long been seen as having the potential to make a worldwide impact. It is funded largely by the French oil giant Total, which helped bring El Hadj Omar Bongo to power as Gabon's president in 1967. The centre was created jointly by the government and Total in 1979, as part of a deal giving France access to Gabon's oilfields.
