1984年夏天，民主党正在筹备下一届总统选举。 参议员沃尔特蒙代尔（Walter Mondale）正在成为可能被提名的人，并且喜欢选择女性作为他的竞选伙伴的想法。 他的五位潜在的副总统候选人中有两位是女性; 除了费拉罗之外，旧金山市长黛安·范斯坦也有可能。 蒙代尔团队选择费拉罗作为候选人的竞选伙伴，希望不仅能动员女性选民，还希望吸引更多来自纽约市和东北部的民族选民，这个地区传统上都是共和党人。 7月19日，民主党宣布费拉罗将在蒙代尔的票上运行，使她成为第一位参加主要党派选举的女性，以及第一位意大利裔美国人。 英国伯明翰大学Essay代写：党派选举 In the summer of 1984, the Democratic Party was preparing for the next presidential election. Senator Walter Mondale is becoming a potential nominee and likes to choose women as his running mate. Two of his five potential vice presidential candidates are women; in addition to Ferraro, San Francisco Mayor Diane Feinstein is also possible. The Mundell team chose Ferraro as the candidate's running mate, hoping to not only mobilize female voters, but also to attract more national voters from New York City and the Northeast. This area is traditionally a Republican. On July 19th, the Democratic Party announced that Ferraro would run on the ticket in Mundell, making her the first woman to participate in the main party elections, as well as the first Italian-American.caseF�t�d ...

要了解晶体管的工作原理，您必须了解半导体如何对电位做出反应。一些半导体将是n型或负极，这意味着材料中的自由电子从负电极（例如，它所连接的电池）向正电极漂移。其他半导体将是p型，在这种情况下，电子填充原子电子壳中的“空穴”，这意味着它表现得好像正粒子从正电极移动到负电极。该类型由特定半导体材料的原子结构决定。现在，考虑一个npn晶体管。晶体管的每一端是n型半导体材料，并且它们之间是p型半导体材料。如果您将这样的设备插入电池，您将看到晶体管是如何工作的：连接到电池负极端的n型区域有助于将电子推进到中间的p型区域。连接到电池正极端的n型区域有助于减缓从p型区域出来的电子。中心的p型区域都有。通过改变每个区域的电位，您可以极大地影响晶体管上电子流的速率。 英国伯明翰大学Essay代写：什么是晶体管？ To understand how a transistor works, you have to understand how semiconductors react to an electric potential. Some semiconductors will be n-type, or negative, which means that free electrons in the material drift from a negative electrode (of, say, a battery it's connected to) toward the positive. Other semiconductors will be p-type, in which case the electrons fill "holes" in the atomic electron shells, meaning that it behaves as if a positive particle is moving from the positive electrode to the negative electrode. The type is determined by the atomic structure of the specific semiconductor material.Now, consider an npn transistor. Each end of the transistor is an n-type semiconductor material and between them is a p-type semiconductor material. If you picture such a device plugged into a battery, you'll see how the transistor works: the n-type region attached to the negative end of the battery helps propel electrons into the middle p-type region. the n-type region attached to the positive...
