IP*根号下的〈（KRP的平?3-KRP+1?D〉。依此去选线.</p> <p>　第五?确定自馈电绕?一般其和原边同名端相反,利用磁复位放出电压感应出电压?</p> <p> </p> </div> <div class="apage" id="showfenye"> <!--资讯分页:start--> <script type="text/javascript"> var pagecont=1; if(pagecont > 2) { var ss = new Cls_jsPage(1, 1, 5, "ss"); ss.setPageSE("helps-84721521501_", ".html"); ss.setPageInput("Page"); ss.setUrl(""); ss.setPageFrist("<a disabled='true'class='ob'>首页</a>", "首页"); ss.setPagePrev("<a disabled='true'class='ob'>上一?/a>", "上一?); ss.setPageNext("<a disabled='true'class='ob'>下一?/a>", "下一?); ss.setPageLast("<a disabled='true'class='ob'>尾页</a>", "尾页"); ss.setPageText("{$PageNum}", "{$PageNum}"); ss.setPageTextF("{$PageTextF}", "{$PageTextF}"); ss.setPageSelect("{$PageNum}", "{$PageNum}"); ss.setPageCss("o", "", ""); ss.setHtml("<div class='o'>{$PageFrist}{$PagePrev}{$PageText}{$PageNext}{$PageLast}</div>"); ss.Write(); } else { document.getElementById("showfenye").style.display="none"; } </script> <!--资讯分页:end--> </div> <div class="gduo"> <span>下一篇：<a disabled="true" href="/Article/gaopinbianyaqishiyon_1.html">高频变压器使用时的几个问?</a></span>上一篇：<a disabled="true" href="/Article/gaopinbianyaqirichan_1.html"> 高频变压器日常维护检查项?/a></div> </div> <div class="info_key"> <span>此文关键字：</span><a target='_blank' href="/Search/index.aspx?1=1&kwd=%e9%ab%98%e9%a2%91%e5%8f%98%e5%8e%8b%e5%99%a8">高频变压?/a> <a target='_blank' href="/Search/index.aspx?1=1&kwd=%e5%bc%80%e5%85%b3%e7%94%b5%e6%ba%90%e5%8f%98%e5%8e%8b%e5%99%a8">开关电源变压器</a> <a target='_blank' href="/Search/index.aspx?1=1&kwd=%e7%94%b5%e6%84%9f%e7%ba%bf%e5%9c%88%e7%94%9f%e4%ba%a7%e5%8e%82%e5%ae%b6">电感线圈生产厂家</a> <a target='_blank' href="/Search/index.aspx?1=1&kwd=%e6%b7%b1%e5%9c%b3%e6%99%a8%e9%a3%9e%e7%94%b5%e5%ad%90">深圳晨飞电子</a> </div> <div class="n_info_con2"> <div> </div> <h4 class="t04"> 关于?span></span>”的相关资讯</h4> <div class="info_b"> <ul class="p_list_ul"> </ul> <div class="clear"> </div> </div> <div class="clear"> </div> </div> </div> <div class="clear"> </div> </div> <!--content:end--> <!--footer:start--> <div class="footer"> <div class="footnav"> <a href="/Helps/aboutus.html">关于晨飞</a>|<a href="http://szchenfeipower.1688.com" target="_blank">晨飞阿里巴巴零售旗舰?/a>|<a href="/job/">人才招聘</a>|<a href="/help/">售后服务中心</a>|<a href="mailto:sales@chenfeipower.com">公司邮箱</a>|<a href="/Sitemap.html">网站地图 </a>|<a href="/Helps/ContactUs.html">联系晨飞</a>|<a href="/user/Register.aspx">用户注册 </a> </div> <div class="font"> <div class="ico3 fl"> <img src="/Skins/Default/Img/Common/ico2.gif" alt="" title="" /></div> <div class="font1 fl"> 地址：深圳市龙岗区龙东鸿基路江南工业???br /> 全国服务热线?000-160-260 <a href="http://www.miitbeian.gov.cn">粤ICP?1044697?1</a><br /> 电话?755-28372867 传真?755-22716226 <br /> <span>阿里巴巴网店<a href="http://szchenfeipower.1688.com" target="_blank">：http://szchenfeipower.1688.com/</a></span><br /> 合作机构：百?阿里巴巴 中国电子商务协会 单仁资讯 实战商业智慧<br /> 诚征媒体合作>> 征求友情链接>> 合作网站列表>> </div> <div class="ico4 fl"> <img src="/Skins/Default/Img/Common/ico3.gif" alt="" title="" /></div> <div class="clear"> </div> </div> </div> <!--footer:end--> <script type="text/javascript"> var _bdhmProtocol = (("https:" == document.location.protocol) ?
