微电网保护问题与传统配电网保护有着极大的不同，典型表现在以下几个方面：a.微电网在并网运行和孤岛运行两种运行方式下，短路电流大小不同且差异很大。b.微电网中电源及相关负荷的接地方式对故障电流的大小影响也很大。c.加入分布式能源后，微电网的双向潮流特性对微电网保护的方向判别也有新的要求。d.发生故障时，微电网与配电网的不同隔离策略需要与微电网保护相结合，这也是微电网保护的关键。(The problem of microgrid protection is very different from that of traditional distribution network protection. Typical manifestations are as follows: a. The short-circuit current of microgrid varies greatly under the two operation modes of grid-connected operation and island operation. B. The grounding mode of power supply and related loads in microgrid also has a great influence on the magnitude of fault current. C. With the addition of distributed energy, the bidirectional power flow characteristics of microgrid also have new requirements for the direction discrimination of microgrid protection. D. When a fault occurs, different isolation strategies of microgrid and distribution network need to be combined with microgrid protection, which is also the key of microgrid protection.)

VB环境下实现U盘复制文件一例，这个程序原有名称叫做“U盘搬运工AutoCopy”，可自动复制文件到U盘，也可把C盘备份到U盘上，也就是拷贝文件的过程，程序在未发现U盘的情况下，要开启监控，操作过程中若选择了放弃操作，监控功能将暂时关闭，拔除U盘之后请重新开启！

这本书很可能让你以为又是一个科学幻想，可能你会说，同类的东西已经看得太多了。 因此，你现在也许会错过这本书，但是，将来你一定会拼命去找这本书，而那时就太晚了。 我的同事告诉我，她看过一个关于超级智能机器的影片。一开始，它们随意屠杀人类。我问她，影片后来结局是什么？她说，机器人被人类感动了，成了人类的朋友。于是我再问她，人类会被蚊子感动吗？会和岩石成为朋友吗？想象远远不及真实！于是，她陷入了沉思…… 一般的科幻片中描述的人工智能机器，它们虽然在很多方面强于人类，但是，总体和人类的差距不大，大致也就是人类和狗的差距。那么，它们最后被人类感动，会和人类成为朋友是很合理的。就像人类会被狗感动，和狗成为朋友一样。但是，那也许只是20或者40年后的智能机器的情况。 不远的将来，人工智能机器的智能将是人类的万亿个万亿倍，它们面对我们，并不像我们面对狗，而是如同我们面对蚊子、跳蚤甚至岩石，当它们消灭我们的时候，如同我们将蚊子拍死，将臭虫冲进下水道，谁会在消灭跳蚤的时候觉得这样太残忍了呢？！ 这也许是人类逃脱不了的宿命，也是德·加里斯教授认为有责任写这本书，我们认为有责任出版这本科学伦理图书的原因。(This book is likely to make you think it is a science fiction, perhaps you may say, the same thing has seen too many. Therefore, you may now miss this book, but in the future you will be hard to find this book, and then it s too late. My colleague told me that she saw a movie about super-intelligent machines. Beginning, they are free to slaughter humans. I asked her later what the ending movie? She said that the robot touched by humans, became the friend of mankind. So I ask her, touched by humans by mosquitoes do? Council and rocks become friends? Imagine far less true! So she mused... A general description of science fiction artificial intelligence machines, although in many respects they are stronger than humans, however, little difference between the overall and humans, which is roughly the gap between humans and dogs. Well, they finally touched by humans, and humans will become friends is very reasonable. Just like humans dogs will be moved, and the dog became friends. But that)
