1、界面更友善
2、优化主代码
3、更新热门词
4、增加搜索排行榜
5、修正切换搜索引擎时左栏不会随所选引擎自动变换问题
例：原http://so.ok881.com/go.asp?Key=唱得响亮&NO=9（这时左栏处于“网页”分类目录）
当将NO=9换成NO=101 时，左栏能自动切换到“影视”分类目录
6、增加相关搜索关键词 （经测试此功能所得关键词会大量被搜索引擎收录） ^_^ 惊喜中...
7、增加知识搜索、行情搜索；
8、更新免费搜索代码，提供多种尺寸及颜色选择。----1, A more friendly interface 2, the main code optimization 3, update 4 popular word to increase the search rankings 5, amendments to the left column when switching search engines do not automatically transform the selected engine problems Example: The original http://so.ok881 .com/go.asp?

Description: 单端反激式开关电源具有结构简单、输入输出电气隔离、电压升／降范围宽、易于多路输出、可靠性高、造价低等优点，广泛应用于小功率场合。然而，由于漏感影响，反激变换器功率开关管关断时将引起电压尖峰，必须用钳位电路加以抑制。由于RCD钳位电路比有源钳位电路更简洁且易实现，因而在小功率变换场合RCD钳位更有实用价值。 -Single-ended flyback switching power supply with a simple structure, input and output electrical isolation, voltage up/down range, easy to multi-output, high reliability and low cost, widely used in low-power occasions. However, due to leakage effects flyback converter power switch off when the voltage spike caused by the need to be inhibited by clamping circuit. RCD clamp circuit as a result of active-clamp circuit than the more concise and easy to realize, and in low-power transform RCD clamp occasions more practical value. Platform: |

Description: 本文提出了一种自动检测和电能质量扰动分类模糊专家系统。有关干扰的类型包括电压骤降，骤升，中断，切换瞬变，冲动，闪烁，谐波和缺口。据推测，在所分析的波形采样的形式提供。傅立叶变换和小波分析，利用独特的功能获得的波形一个模糊专家系统为主体的决定有关的干扰类型而设计的。仿真研究，验证了该方法的比较研究人工神经网络为基础的分类方法和该方法研究的准确性也报告，以显示该方法的优点-This paper presents a fuzzy-expert system for automated detection and classification of power quality disturbances. The types of concerned disturbances include voltage sags, swells, interruptions, switching transients, impulses, flickers, harmonics, and notches. It is assumed that the analyzed waveforms are available in sampled form. Fourier transform and wavelet analysis are utilized to obtain unique features for the waveforms A fuzzy-expert system is designed for making a decision regarding the type of the disturbance. Simulation studies are presented to verify the accuracy of the proposed approach Comparison studies between an Artificial Neural Network based classification technique and the proposed approach are also reported to show the advantages of the proposed approach.
