达到目标

So education modernization of China must take the "compress" span development tactic, while the extreme imbalance of education development among different Chinese areas forms interlocal imbalance development with hiberarchy list. Endogenetic pursuant mode needs kinds of conditions.

中国的教育现代化追赶的目标是在较短的时间内达到其他国家经过数百年发展所达到的教育现代化水平，因此，中国的教育现代化必须采取"压缩"的跨越式发展战略；而中国各地区之间教育发展的极端不平衡性，使这种追赶形成了各地区非均衡发展的层级序列。

The thesis contains five chapters. The first chapter summarizes the development and research of switched reluctance drive, discusses the main research direction, and explains the main work in this paper. In chapter 2, hardware system which includes the design of power converter and various control circuit is discussed. TMS320LF2407 DSP is used to design the hardware circuits of SRM control system, and design details including the current detection, position sensing, fault protection, speed detecting, keyboard and display etc. are provided. Because of the full use of the abundant peripheral resources of DSP, it comes to the aim simplifying the circuit structure and heightening the reliability. In chapter 3, the application of neural network on SRM control system is introduced, a new the application of neural network and the method of sampling is proposed and a simulation system based on Matlab/Simulink is established. Chapter 4 discusses the routine designing issue. Because the modularized programming method is adopted, and multi-interrupt processing technique is used, operation efficiency of the control software is highly raised. At last, the foregoing SRM control system is tested. Speed adjustment is realized, and other targets on the research and design of SRM control system are reached, which establishes a good foundation for further research.

I have tried to build regions from top to bottom using more SPS at the top and working down to LPS and softies through the bottom. As I looked through the progression of the tank during the process of writing this, I realize I have had mixed results in this goal and have found myself buying and selling colonies throughout its life as things grew that aesthetically no longer worked, fit, or looked good. I think that with the current setup of corals and frags I have a better balanced tank with a diverse selection that will grow in nicely.

我在山顶放SPS，然后下面放 LPS，最下面放软珊瑚，我在写这个记录时，我看着它们的成长，我发现，最终的结果已经达到我开缸时的目标，同时，在我不断买进和卖出珊瑚的同时，审美观已经变得比较次要，只要它们在生长，我就觉得是最美的，现在的设定和珊瑚，还有断支，和多样性选择上，刚好达到平衡

Most of Chinese GPR have not as good performances as ones abroad. In the paper, the GPR system developed by us employs several optimization techniques to enhance the system performances, including antenna, sampling-hold circuit, orientation wheel, function of system software, multithreading, and signal processing algorithms. As the result the system works more well with these techniques, and its azimuth and distance resolution of 10 cm has been achieved with detection depth of more than 50 cm.
