My name is XX,24 years old,Koreaner,and graduated from XX major on july this year.i have dad ,mom,and sister in my family.father is a worker in a airport,while mother is a teacher.i grew up at such traditional family,so parents were strict with me,they tought me much.until graduation from high school,I was able to enterYanbian University without parents' care.instead of feeling reluctant to part with parents,I was imvolved in new life rapidly.because of my lively personality and easy-going,teachers and classmates spoke highly of me.at other times,I loved reading and searching information in the internet.morover,I reinforced own Korean,english and computer competency continuously,took advantage of two years to study korean in the opportunity class,and then met many foreign friends to proceed mutual learning as partners.over my four-studing out of home,I cultivated strong characteristic,which made me overcome many difficulties from studying nad living.i majored in education technology ,the professional subjects contain three aspects about hardware and software on computer,education and use of multimedia,for example,OFFICE software,IMAGE-PROCE ING software,NLE software and various computer language,data organization,digit circuit,education,educational psychology,distance learning etc.i valuing practice often do come part-time jobs to accumulate some social practice experiences by making use of outside school hours ,except for the basic curriculums in the school.in my leasure time,I often go sporting,such as mountaineering,swimming,riding bicycle and so on,as well as paricipation some activities organized by sc

我叫XX，今年24岁，朝鲜族，今年7月毕业于XX专业。家庭成员有爸爸、妈妈和姐姐，父亲是一名飞机厂工人，母亲是一名人民教师，从小在这样传统的家庭中成长，父母对我的管教也很严格，教会了我许多做人的道理。直到高中毕业，离开父母呵护的臂膀来到了延边大学，没有对家的恋恋不舍，而是很快的融入到了新的生活中，由于我的性格活泼开朗并且随和，老师和同学们对我的评价也都非常好，平时我喜欢看书和上网浏览信息，另外不断加强自身的韩国语、英语和计算机能力，利用两年时间在补习班学习了韩国语，并认识了许多外国朋友结成partner互补学习，在外求学的四年中，我养成了坚强的性格，使我克服了许多学习上和生活中的一些困难。我的专业是教育技术学，专业课程包括计算机的硬件及软件、教育学和多媒体的使用三大方面。OFFICE软件、图象处理软件、非编软件以及各种计算机语言数据结构，数字电路，教育学、教育心理学、远程教育等。注重实践的我除了学校的基本课程外，经常利用课余时间做一些兼职以积累一定的社会实践经验，平时还喜欢做一些运动，例如登山、游泳、骑自行车等，并经常参加学校里组织的一些活动。开朗乐观是我对待生活的态度，吃苦耐劳是我对待工作的原则。

The measuring mechanism of diffusion nephelometer and methods for its improvement were studied,the result of which shows that the diffusion nephelometer using a new-type monochromatic electronic light source and provided with a luminous intensity stabilizing circuit is featured by high accuracy and sensitivity in case of narrow range of NTU,with good linearity up to 100 NTU,without frequent adjustment of zero point an

探讨散射式浊度仪的测试机理和改进方法。测试结果表明，采用新型单色电子光源和配备发光强度稳定电路的散射式浊度仪具有低浊度范围准确性和灵敏度高，至100NTU线性好，不须经常调整零点和重新标定，耗电量少，光源寿命长和抗色度干扰能力强等特点，适用于水厂提高滤池效果和监测出水水质。

The technique made full use of the characteristic of PR controller which can realize zero steady-state error in AC input signal in stationary frame. In the method, the active and reactive current component in the vector control strategy were transformed in the stationary frame to achieve the objective of keeping the DC-link voltage constant, adjusting the power factor and decoupling the active and reactive power. Compared with conventional double close-loop proportional integral controller, the PR technique is better in harmonic compensation without the complex rotating frame transformation and the couple or feedback voltage which is easily influenced by temperature and circuit parameters. The control algorithm is easy to be realized while the robustness and power quality is improved.

该方法充分利用了PR控制器能够在静止坐标系下对交流输入信号无静差控制的优势，将矢量控制策略下的有功电流和无功电流分量转换到静止坐标系下进行调节，实现网侧变换器维持直流电压稳定和调节功率因数的控制任务和双馈电机有功、无功功率的解耦控制，与传统的双闭环PI控制相比，该策略无需繁琐的坐标旋转变换，不存在受温度及电路参数影响的耦合项和前馈补偿项，且易于实现对系统低次谐波电流的补偿，减小了控制算法实现难度，提高了控制系统的鲁棒性和电网电能质量。

Based on these design guides, the analysis and design of a low phase noise and low power dissipation, with 0. 18μm CMOS process, integrated Colpitts crystal oscillator with automatic gain controlled feedback loop as the amplitude-limiting technique, low dropout voltage regulation with band gap reference voltage and frequency tuning monotonicity guaranteed by digitally controlled variable capacitor array is performed to revise influence caused by process, voltage and temperature conditions for. handset. The oscillation with very stable amplitude value and frequency value is achieved.
