The thesis based on Yellow River Diversion Project. Through the research of the existing design of the supervising system of Yellow River Diversion Project, this passage pointed out some problems hard to be dealt with as follows:(1) Owing to the dispersion of control points and remote transfers of data, it cost a lot to construct the network of the supervising system and it was hard to implement the construction.(2) The connection mode of network needed to be taken into acount. Once the configuration of network changed or the nodes increased, the supervising system needed to be reconfigured.(3) Owing to the tanglesome physical communication line, the man-made communication error happened frequently.(4) When the communication malfunction occured, it needed various engineers to check and repair the fault.(5) It cost a lot to operate and maintain the supervising system.

本文以世界银行援建项目&Yellow River Diversion Project&(引黄入晋工程，编号：0015-K81062)为背景，在对引黄入晋工程的远程监控系统进行研究分析的过程中，指出了该系统在目前采用的有线光纤和有线电缆通讯技术下难以处理的一些问题：(1)由于监控点分散且传输距离较远，有线光纤和有线电缆的网络建设成本很高，实施困难；(2)需要考虑节点之间的连接形式，一旦网络结构发生变化或节点需要扩充，监控系统便需要调整，耗费大量的人力物力；(3)由于系统庞大，通讯的物理线路较为繁乱，在建设和维护阶段容易出现人为触碰等引起的通讯故障；(4)在出现通讯故障时，需要多方人员配合进行故障检测，不仅耗费人力和物力，且不利于故障排除；(5)运行和维护成本较高，需要很多运行维护人员进行大量繁杂的工作。

Different from the routine trapeziform curve of frequency converting speed system, the motor's speed was adjusted according to exponential curve , and soft braking was realized by detent unit contained in the power module, enhancing the fluency and stability when running.

According to the definition and the distribution of VSR's voltage space vector, the introduction of a rule-based SVPWM current control strategy, with non-fixed switching frequency and dual hysteresis loops, that obviously improves the performance of current control. Based on two kinds of control strategies of VSR under unbalanced grid condition, the introduction of a new VSR control strategy featuring undamped-oscillation that simplifies the controller structure and effectively improves VSR's performance under unbalanced grid condition. A systematic description of the state switching in trilogic PWM signal generation of threephase CSR by using the conversion between bilogic and trilogic switching functions.

作者在如下工作的基础上对PWM整流器的一些关键问题提出了自己的研究思路、观点和方法：根据PWM整流器网侧矢量关系，直观地描述了其四象限运行的基本原理及特征；定量分析了VSR、CSR的PWM换相过程及波形特征；引入等效变压器模型并详细分析了VSR、CSR基于d—q模型的动、静态特性；提出了满足四象限有功、无功运行指标时的VSR交流侧电感设计方法；并提出了依据控制系统跟随性和抗扰性性能指标设计VSR、CSR直流侧储能元件的参数计算方法；在研究了VSR电流控制策略基础上，提出了影响VSR电流控制的几个要素，并进行了定量分析；根据VSR空间电压矢量的定义及分布，提出了基于规则控制的不定频滞环空间矢量PWM电流控制策略，并由此提出了具有双滞环特性的不定频滞环优化SVPWM电流控制策略，有效地改进了滞环PWM电流控制性能。

And so has come into an inevitable trend that administrative power should be exercised in accordance with laws, thougn evil phenomena of unfairness, insolemnness, dishonestness and uncivilizedness still exist in plenty in enforcing laws in our country.

因之 ，行政权力运行法制化成了一种必然趋势，尽管我国在行政权力运行过程中，执法不公、不严、不廉、不文明的不良现象仍大量存在。

This method can reduce sludge production radically and virtually. The effectiveness of eight metabolic uncouplers in reducing sludge production from activated sludge process were compared to screen effective, cheap and non-toxic available uncoupling chemicals and determined the long-term uncoupler effects of 3, 3', 4', 5-tetrachlorosalicylanilide in activated sludge batch cultures.

首先比较筛选了对污泥的减量化效果好、价廉、无毒的化学解偶联剂；在此基础上，研究了添加3，3′，4′，5-四氯水杨酰苯胺的分批活性污泥工艺的剩余污泥减量化效果，以及对工艺运行效能和污泥性能的影响；着重进行了添加TCS的活性污泥工艺、好氧—沉淀—缺氧工艺、添加TCS的OSA联合工艺的连续运行试验研究。

We all experience the poor quality of software: programs "freeze", programs don't work as expected, user interfaces are unintuitive, programs are too slow etc.

我们大家可能都有这样的经历，软件的质量很不理想：程序&死机&，不按预期的要求运行，用户界面很难理解，运行速度不能忍受。

It's better to run the unsharp mask filter multiple times at smaller settings rather than to run it once at a large setting.

运行多次较小设置的unsharp mask滤镜比一次运行一个大数值的设置要好。

It has become the countrys polar industry. However, the industry has been functioning unstably since the market economy reform, even with lumping fluctuation from time to time, which indicates that the government has not made an accurate assessment on its development, and macroeconomic controlling policy does not work effectively, particularly in go-aheadism and guidance.

然而，我国房地产业自从市场化以来一直处于非平稳的运行状态中，并且有的时期波动较大，这种运行状况表明，我国政府对房地产业的发展状况评判准确性不足，宏观经济政策调控效果不够理想，尤其是政策的主动性和引导性不强。

Author 2004 Chinese economy moves with Chinese economy ten years even development course union of a few years rises, already from a small clue one can see that is coming, operate from a strategically advantageous position, run macroscopical economy to rise with union of microcosmic economy operation undertake an analysis, both neither as to lie between boots to flinch to the person urticant feeling, unapt see tree does not see a forest only.

作者把2004年中国经济运行与中国经济十几年甚至几十年的发展历程结合起来，既见微知著，又高屋建瓴，把宏观经济运行与微观经济运营结合起来进行分析，既不至于给人隔靴挠痒之感，又不至于只见树木不见森林。
