在光耦光敏三极管的集电极或发射极直接接负载电阻即可满足较小的负载要求；在光耦光敏三极管的发射极加三极管放大驱动，通过两只光电耦合器构成的推挽式电路以及通过增加光敏三极管基极正反馈，既达到较强的负载能力，提高了功率接口的抗干扰能力，克服了光耦的输出功率不足的缺点，又提高光耦的开关速度，克服了由于光耦自身存在的分布电容，对传输速度造成影响。

My practice uses his mood to perhaps be used to make an issue of to revise namely, for example eider down by maintain this article Http://www.yurongbei.net/html/knowledge/baoyang.html, baidu one, have 14000 much themes, so informal look for an article, look next or for many times, draw up in silent come, him likelihood memory is not quite good, wrote oneself basically to think of only so probably meaning, add bit of him thing again, made the unique text on the net.

我的做法就是用自己的语气或者习惯做文章修改，例如羽绒被的保养这文章http：//www.yurongbei.net/html/knowledge/baoyang.html，百度一下，有14000多的主题，那么随便找一篇文章，然后看一次或者多次，在默写出来，可能本人记忆力不太好，所以基本只写了自己想到的大概意思，再加点自己东西进去，就成为了网上独一无二的文章了。

Analysis of the personage inside course of study says, wo Erma increases the 10 thousand need that buy the home to buy vast land, need buys a lot of equipment, need a lot of storage, and it is OK to clean out treasure to need to add a computer only.

业内人士分析称，沃尔玛增加一万买家需要买巨大的地，需要买很多的设备，需要很多的仓储，而淘宝只需要增加一台电脑就可以了。

In addition, the Export link to add some help to exchange links, as some prepared to chain to the head when you stand, and what you will see an exchange of the link station, if he saw you a few good links to the station, he They may think that you and the exchange of links, your site should be pretty good.

另外，添加一些导出链接对交换链接有所帮助，因为一些站长准备链向你站的时候，都会看你和哪些站交换了链接，如果他看到你链接了几个还不错的站，他可能以为你和他们交换了链接，你的站应该还不错。

It is the exterior link problem of a website again, generally speaking, exterior link is more, the quality of the website of the link is higher, better to the rank of your website, but this is not to say to if,jump over good; more more absolutely outside group of hair machine are sent suddenly, connect, the will be GOOGLE penalty that awaits then is the problem of retrorse link next, namely if your website is done perfectly if, other website can add your website link on his page, of course this also can pass commutative catenary fetch to come true.

再次是一个网站的外部链接问题，一般来说，外部链接越多，链接的网站的质量越高，对你的网站的排名越好，但这绝不是说越多越好；如果把有群发机猛发外连，那等待的将是GOOGLE的惩罚然后是反向链接的问题，即你的网站如果做的相当不错的话，别的网站会在自己的页面上加上你的网站链接，当然这个也可以通过交换链接来实现。

Graph below the Gadgets that we add a map again, we also open this process, this procedure is very simple also, so a few, explain simply, this is the map that Gu Ge has made, making a map to fabricant of a website is very troublesome, and it is good to spent a long time to also do not have something made to order, our Gu Ge has been done now, and the way with was offerred so good.

下面我们再加一个地图的Gadgets，我们也把这个程序打开一下，这个程序也非常简单，就这么几行，简单解释一下，这个是谷歌已经做好的地图，对于一个网站制作者来说制作地图是很麻烦的，而且花了很长时间也不一定做得好，现在我们谷歌已经做好了，而且提供了这么好的方式。

Famous record company sues 11 international jointly Yahoo Chinese website, 47 pieces of special that offer them to enjoy recording fabricant to counterpoise to the public add up to 233 song.

11家国际知名唱片公司联合起诉雅虎中文网站，向公众提供他们享有录音制作者权的47张专辑共计233首歌曲。

When fishing a Zulu or Floating worm subsurface, but using a traditional "weightless" technique, you may want to: use a larger hook (Fig. 16), add some weight to your hook such as "Sticky Weight"(Fig. 17) or SuspenStrips, use a swivel and a short leader (Fig. 18) or other technique to cause the lure to sink to the desired depth or to suspend it.

当你想使用软饵 ZULU 或是漂浮型软虫，却需要采用无坠钓法在中层水域施钓，你可以采用大一些的软虫钩（图片16），在钩的中部添加一些重量，如粘铅，（图片17），或是使用八字环，接一小段前导线（图片18），利用可以有的办法，原则上掌握添加重量的比例，使其达到施钓水层或者驻留在某个高度。

The innovation of model is adopting mobile agent to replace RFC and OORPC to implement the connect and communication between the client and server, in this way, it can remove the disadvantage of the traditional middleware and add the intelligence, flexility and adaption to the network to the communication between the client and server.

其创新之处在于，此模型采用移动Agent取代传统的RPC和对象RPC机制实现客户与服务器的智能连接，从而解决传统中间件的不足。使得客户端和服务器间的连接和通信具有智能性，灵活性和良好的网络适应性。

In this article two functional modes of the Fly-back Converter (Continuous Conduct Mode and Discontinuous Conduct Mode) are particularly analyzed, which include their characteristics, applications, the critical pattern of two functional modes is argued, both the exact boundary from the angle of circuit parameters is crystallized, at the same time, basic principle of PFC under the DCM mode is introduced, which settle theoretical basis for the subsequent design; by establishing the mathematic model of the converter, a further investigation of the configuration is made, qualitatively and quantitatively, analyzed to settle exactly theoretical basis for the subsequent emulation and the experimental parameter; from the angle of steady-state analysis, the transfer function of the system is deduced to establish dynamic small-signal state equation, emulating the system with the help of matlab, then according to the simulation result and the theory of PFC revise the system, lastly, we adopt the project which add a zero-pole compensator to the voltage loop, by this way, a satisfied system performance is gained and the PFC scheme is ensured successfully; finally, based on the previously-done work, we combining with the situation of specific design requirement, acquired the numerical value of each unit devices in this converter

详细分析了反激式变换器的两种工作状态，连续模式(Continuous Conduct Mode ，简称CCM)和断续模式(Discontinuous Conduct Mode，简称DCM)以及各自的特点、应用场合，论证了两种工作状态的临界模式，从电路参数的角度明确了二者的界限，同时还介绍了DCM模式下PFC的基本原理，为后面的设计奠定理论基础；通过对整个变换器系统建立准确的数学模型，对此变换器的电路结构做了进一步的研究，定性、定量地分析了变换器各部分的工作状态，为仿真和实验参数的确定以及电路参数的优化提供理论依据；从稳态分析的角度，为系统建立了动态小信号状态方程并推导出系统的传递函数，利用matlab对系统进行仿真，进而根据仿真结果以及PFC的相关理论对系统进行校正，采用在电压环加入零点—极点补偿器的设计方案，得到了满意的系统特性并且保证了PFC的顺利实现；最后，在前面所做工作的基础上，结合设计要求计算出此变换器系统中每个元器件的数值，利用Pspice对其进行了仿真、优化，然后根据仿真结果搭建了硬件电路。
