如题，以前听朋友说是进口的，不过已经过了5年了，不知是否能够自研了？有清楚地说说！如题，以前听朋友说是进口的，不过已经过了5年了，不知是否能够自研了？有清楚地说说！

三楼之内必封
<p>怎么这么象网特？</p>
<p>早就搞定了，</p><p>不过老子就是不说，</p><p>告诉你一句，</p><p>不止铁氧体的，</p><p>其他新型材料的都有，</p><p>领先水平嘛，</p><p>自然是保密滴。</p>
<p>晕倒，看我以前的帖子就知道了，我在铁路工作的。网特哪那么好抓啊！</p><p>下面是一篇关于网络间谍公司的短文（朱泰其的，偶正努力考研中）</p><p> Wild Bill Donovan would have loved the Internet. The American spymaster who built the Office of Strategic Services in World War II and later laid the roots for the CIA was fascinated with information. Donovan believed in using whatever tools came to hand in the “great game” of espionage -- spying as a “profession.” These days the Net, which has already re-made such everyday pastimes as buying books and sending mail, is reshaping Donovan’s vocation as well. <br/> <br/> The latest revolution isn’t simply a matter of gentlemen reading other gentlemen’s e-mail. That kind of electronic spying has been going on for decades. In the past three or four years, the World Wide Web has given birth to a whole industry of point-and-click spying. The spooks call it “open source intelligence,” and as the Net grows, it is becoming increasingly influential. In 1995 the CIA held a contest to see who could compile the most data about Burundi. The winner, by a large margin, was a tiny Virginia company called Open Source Solutions, whose clear advantage was its mastery of the electronic world. <br/> <br/> Among the firms making the biggest splash in this new world is Straitford, Inc., a private intelligence-analysis firm based in Austin, Texas. Straitford makes money by selling the results of spying (covering Chile and Russia) to corporations like energy-services firm McDermott International. Many of its predictions are available online at <a href="http://www.straitford.com">www.straitford.com</a>.<br/> <br/> Straitford president George Friedman says he sees the online world as a kind of mutually reinforcing tool for both information collection and distribution, a spymaster’s dream. Last week his firm was busy vacuuming up data bits from the far corners of the world and predicting a crisis in Ukraine. “As soon as that report runs, we’ll suddenly get 500 new Internet sign-ups from Ukraine,” says Friedman, a former political science professor. “And we’ll hear back from some of them.” Open-source spying does have its risk, of course, since it can be difficult to tell good information from bad. That’s where Straitford earns its keep.<br/> <br/> Friedman relies on a lean staff of 20 in Austin. Several of his staff members have military intelligence backgrounds. He sees the firm’s outsider status as the key to its success. Straitford briefs don’t sound like usual Washington back-and-forthing, whereby agencies avoid dramatic declarations on the chance they might be wrong. Straitford, says Friedman, takes pride in its independent voice. (396 words)</p><p> Wild Bill Donovan 本来是会喜欢互联网的。这位在第二次世界大战中建立战略服务办公处并在后来为中央情报局奠定基础的美国间谍大师对情报独具钟情。在作为“职业”的间谍活动“大游戏”中，Donovan 信赖使用任何到手的工具。如今，由于网络已经改变了购物和发邮件这样的日常活动，它也在改变Donovan所从事的间谍职业。<br/> 最近这场用互联网来改变间谍活动的革命并不仅仅是一些先生读另一些先生的电子邮件。那种电子间谍活动已经进行了数十年了。在过去的三、四年中互联网创建了点击式间谍活动的整整一个行业。这些间谍称它为“敞开来源的情报”，并且随着网络的发展，这个行业的影响越来越大。1995年中央情报局举行了一次竞赛，看谁能够收集和汇编出有关布隆迪的最多的资料。遥遥领先的获胜者是弗吉尼亚州的一家小公司，名叫“敞开来源解决办法”。这个公司的明显优势是，它掌握了电子世界。<br/> 在这个新的领域引起轰动的公司中有Straitford公司 － 一家以得克萨斯州奥斯汀为基地的私人情报分析公司。Straitford靠把间谍活动（包括从智利到俄罗斯的国家）成果卖给公司，如McDermott国际能源服务公司，来赚钱的。它的许多预测可以在<a href="http://www.straitford.com">www.straitford.com</a>. 网站的网上得到。<br/> Straitford公司董事丧George Friedman说，他把网上世界看作是一种对情报收集和发送互惠的有力工具。上周他的公司忙于全力搜集来自世界各地的资料信息并预测在乌克兰将会发生一场危机。“那个报导一发表，我们将立刻从乌克兰收到500条新的互联网贴子，”前任政治学教授Friedman说。“并且我们将从其中一些帖子中收到回音。”敞开来源的间谍活动确实有它的风险，因为很难区别有用的情报和无用的情报。可那就是Straitford公司挣钱自立之所在。<br/> Friedman 依靠在奥斯汀的仅仅20人的人员。其中有几人有军事情报工作的背景。他把公司所处的局外人的地位看作是公司成功的关键。Straitford发出的短讯并不像通常华盛顿的来往报告，因此，情报机构避免做出激动人心的正式声明，担心这些声明可能有误。Friedman说，Straitford公司为其不为人左右的声音而自豪。</p>
<p>这东西我国到不是没有，只是听说性能不稳定，功率也不高，难以满足雷达的要求，刚在空军版看了一篇我国固态相控阵雷达的帖子，所以才想要问问的。不知达到实用化了没有，都过了好几年了。</p>[em06][em06][em06][em06][em06]
另外，这种元器件军民两用，不是专用于军事的，不过军用的性能超强就是了。
成品率还是低了些.
<p>成品率低到不要紧，关键是成品的那部分性能能否满足要求！？相移体可是雷达的心脏啊！只要有合乎要求的再改进改进工艺，增加增加精密设备就好，被人卡脖子的滋味不好受啊，我在铁路感受颇深！</p>[em06][em06][em06][em06][em06][em06]
铁氧体相移器本身并不是很复杂,理论也很简单,主要还是工艺不行.22.5,45,90.180,基实也就这几个相位,但做起来真难.非线性的铁磁体,张量磁导率,分析起来我头就大了,每次上这部分内容我都叫学生提前预习个2遍.
