差分线间距走多少合理？
DDR clock一般都要差分阻抗在100ohm左右。 线距和PCB板叠层，线宽，介电常数都有关系。你可以用hyperlynx仿真得到。现在身边的一个项目线宽4.7mil，线距15mil左右，差不多跟你1.5倍线宽一致。
谈电脑对学习的影响 英语作文
The impact of computers on learning
In recent years, with the rapid development of information technology, the increasing popularity of the use of computers, is a profound impact on peoples thinking, learning and work. Such a positive impact on both, the positive side, there are negative, the negative side. In this paper, the computer network of secondary school students on language learning a few words on the negative impact of opinion with a view to arouse the concern of the language industry peers, brainstorm, WTO, the promotion of language teaching. I, as a secondary language teachers to use computers for many years, the computer network of personal experience, while more concerned about teaching students to use computers, and for some surveys and interviews. By understanding and feedback and found that the computer network of secondary school students the negative effects of language learning is mainly manifested in the following areas: First, the impact of the interest in language learning Computer as a high-tech products, its innovative, intuitive, interactive, high-performance characteristics of the people are deeply attracted, and the network information by virtue of its large, open and strong features such as all the rage. The psychological characteristics of middle school students generally out of curiosity, thirst for knowledge, and desire to communication, computer networks to meet their psychological needs become the best carrier. Once exposed to computers, the Internet Society, is often this way, stop. Games, chat, download their favorites, enjoy the CD, visit the website is the best regulator. Addicted to them, including their language learning, including the interest in other activities tend to weaken. In contrast, our language teaching, The contents of old, means a single, small amount of information, the attractiveness of this is not strong, powerful computer networks in the "offensive" in front of a considerable number of students with poor self-control even more emphasis on natural language learning, and some even think that listening to language lessons also not as good as online learning software to read and use language. Second, the impact of language learning habits Language learning there is a very important task - to develop good language learning habits, such as writing habits, the habit of words make sentences, inspection tool of the habits, the habit of reading and so on. Long-term use of computer networks will gradually change these habits of students. For example, the computer keyboard to enter text on long-term people use the keyboard, writing quality, speed will be definitely affected, and this has proved to be the Institute. Some students are subject to certain media misled into believing that the development of computer technology with the future than keyboard input, voice input means to a more advanced, do not write do not write the word crucial. They do not understand Chinese characters to write is not only a symbol of our national cultural heritage is an essential, irreplaceable carrier, it is a written obligation, a responsibility. As students make sentences words, by the impact of online media is even more obvious: the three sentences pretty close copy,美目, writing in the common share, domain names, even nicknames to the students, also known as hackers, e-mail. Of course, for those with new words derived from the computer is not not available, with good will used to make wonderful eloquence of mining, Shenghui composition. However, if the abuse of, or away from it seems that the word can not find other word to express emotion, I am afraid, has become a bad habit. Third, the psychological impact on the quality of reading Computer network informative, interactive, and link-rich, easy operation and convenient features of the students indulge in adventure, profit-oriented mentality, they surf the Internet quickly at the same time the shuttle, perhaps he has lost the most precious to read the psychological quality -- mentality of peaceful resistance, a lonely, single-minded lasting. No wonder, we are living in this day and age characteristics of the largest on a "fast" word: faster, and faster language, express, fast food, express delivery ... ... to have a most unusual phenomenon for the card - sitting in front of the television, a high school student hand remote control which is not kept "turned" a TV? fickleness, intentions are not professionals, can not be sustained is the current attitude of many middle school students in reading, this is the language of the enemy of reading. Fourth, the impact of style Secondary school students are at their prime, the youth grow, they should show the composition vibrant, pure and healthy style of writing. However, in order to vent and sensational as the mainstream literature of the network composition of secondary school students have had the impact that can not be ignored, they often unconsciously, to imitate. Or cynicism, dissatisfaction with reality, with full papers and curse of treason; or vent their inner sense of loneliness and emptiness, one decadent style. Some go so far as to write the teacher did not complete the composition layout, but behind closed doors, thinking, writing a number of touch with reality or ambiguous style "different text." The face of it, thinking and innovative, but in reality too vague, confused thinking, unreasonable sentence, it can not bear to single reading. Fifth, the impact of art and aesthetic appreciation of literature In addition to language teaching language training, but also bear the character mold, purification of the mind, students have a certain level of literary appreciation of the aesthetic and noble task. However, classroom teaching efforts in this regard are being a little bit of offset from the turbulent waves of the network that pays top academics, dazzling software varies, many more than a fancy Web site, less than intrinsic, ideological, and artistic weaker, and some are even full of sex and violence. Plasticity, and discrimination influenced poor students, it is bound to affect their level of appreciation and aesthetic tendencies. Many secondary school students obsessed with cartoons, comic books, as the tradition of conservative, The alternative when the fashionable, good or bad, regardless, MO identify beauty, even the minimum humane care and compassion are lost, where also we talk about art and aesthetic appreciation of literature.
