查询词典 station amplifier

S1 is then changed to position 1. The voltage stored on C1 is inserted between the output and inverting input of the amplifier and the output of the amplifier changes by VIN to maintain the amplifier input at the input offset voltage. The output then changes from (VOS + IbiasR2) to (VIN + IbiasR2) as S1 is changed from position 2 to position 1. Amplifier bias current is supplied through R2 from the output of the amplifier or from C2 when S1 is in position 2 and position 1 respectively. R3 serves to reduce the offset at the amplifier output if the amplifier must have maximum linear range or if it is desired to DC couple the amplifier.

接着 S1 拨到位置 1，使 C1 的电压加在放大器的输出端和反相输入端之间，(由于电容端电压不能突变，所以)输出端的电压将产生大小等于 VIN 的变化，使放大器输入端维持输入失调电压，即当开关 S1 从位置 2 拨到位置 1 时，输出端电压将从(VOS + IbiasR2)变为(VIN + IbiasR2)。S1 处于位置 2 时，放大器的偏置电流是由输出端经电阻 R2 提供的，当 S1 转向位置 1 时则由 C2 提供。R3 的作用是降低输出失调电压，如果要求放大器具有最大的线性范围，或者采用直流耦合，就应该使用该电容。

The objectives of this paper were to investigate the simulation and design of continuous multiple-station rolling forming process for a U-Section Steel Bar by CAE software-DEFORMTM Due to the limitation of elements number using a short strip 120mm went through all the stations to simulate the real continuous rolling forming on factory The roller gap was fixed as 0 30mm roll speed was 20 rad/sec and progressive angles were all equal for each rolling process which were the formed angle divided by by the number of station Three rolling processes were selected with 6 9 and 12 stations respectively During simulation processes two cases occurred Case A the strip was through a single station Case B the strip across two stations Because the strip laterals side was stretched and twisted during the process The model of case B closer to the practical process than case A and the calculated stress and strain on the tip of U section for case A were lower than these for case B by up to 15% From the result of case B for each process the stress for 12-station process was smallest 9-station process second and 6-station process next Because less-station can save larger cost and forming time but the bigger stress and strain for 6-station caused wrinkles on lateral sides not found on 9-station and 12-station Therefore 9-station process was a more suitable design than 12-station process smaller stretched and twisted and stress The progressive angles for 12-station was 7 5?

本文主要是以DEFORMTM有限元素软体模拟U型钢片连续道次成型与单一道次成型以确认单一道次模拟的是否可取代连续道次模拟之研究。因DEFORMTM 软体对於网格元素上的限制故使用较短素材120mm通过所有的成型站以模拟工厂实际连续成形方法。辊轮间隙固定为0 3mm；辊轮转速为20 rad/sec；弯曲角度的方法为将成型角度平均除以成型站数。有三种辊轮成型方式被选择分别为6站，9站，与12站。在模拟的过程中有两种现象会产生 Case A，素材通过单一成型站。Case B，素材会通过两个成型站。因为在模拟过程中素材的两端会有拉应力与扭力。Case B的模拟比Case A像实际的制程，并计算应力与应变在U型断面的Tip部中可发现Case A比Case B低约15%。从Case B的每站的结果可以得知，12站的成型应力最小，9站次之，6站最后。

In 7 years, I filed domain name of a Cn, began the beginning of exchanging station of my network address discharge, name lilac community, domain name Kissdh.cn begins to do do not have a few people and me to connect, after Baidu collects my station, gradually the picture stands, film station great majority looks for me actively to join, my way station arrives from exceed of thousands of IP tens of thousands of IP, because national policy is swept,fizzle out in this moment dozen of blame, my station ever was depilated by Baidu for a time or fall authority, there is policy on, there is the way to deal with a situation below, I stand be about to website name instead is normal character, on content also the character with normal instead of a lot of network address word that cause fire, the following day Baidu is collected afresh again go back, mix in the end of the year 8 the beginning of the year when, my discharge exchanging station is close to 80 thousand IP for a time, the space changed a few, can be in right now, the domain name that home major suspect seems adult content did abhorrent CNNIC to ban entirely, include 10 thousand networks, new network, new each other inside the CN rice of exchanging station of N much discharge is avoided without laborious entirely at difficult, boiled in discharge Abelian group in a moment, it is to blame CNNIC for the most part this kind of outrageous conduct, discharge exchanging station as platform of discharge change trains, no more than is to make a discharge transition, how does picture of likelihood occurrence pornography reach video?

07年中，我申请了一个cn域名，开始了我的网址流量交换站的开始，并取名"丁香社区"，域名kissdh.cn开始做没几个人和我连，百度收录我的站后，渐渐的图片站，电影站大多数都主动找我连接，我的小站从几千IP逾越到几万IP，就在这个时候因国家政策扫黄打非，我的站曾一度被百度拔毛或降权，上有政策，下有对策，我立即将网站名改为正规文字，内容上也把许多惹火的网址字眼改为正常的文字，第二天百度就又就重新收录回去，在年底和08年初的时候，我的流量交换站一度接近8万IP，空间都换了几个，可就在此时，可恶的CNNIC将国内大部分疑似成人内容的域名全部做了封杀，包括万网，新网，新互在内的N多流量交换站的CN米全部没有辛免于难，霎时流量交换群里沸腾了，大部分都是抱怨CNNIC这种可恶的行为，流量交换站做为流量中转平台，无非是做个流量转换，怎么可能出现色情图片及视频呢？

Across joins 2 be: Both sides makes alternate connection, mutual promotion opposite party needs the keyword of promotion, if A B C D stands, a B station is my site, c D station is site of the other side, it is me above all with A the station puts join of station of C of the other side, the other side joins with D station my B stands, such quality that makes the A station that the condition is me asks like Pr and the condition of the D station of the other side is a balance, such we just make connection significant, simple for the rank that such purpose is the C station that we popularize him in side the other side, the other side is popularizing the rank that our B stands, be mutual benefit actually, a lot of had not become alternate connective friend, should turn to them a little only next turns, they are muddleheaded, it is a dot really so it is cerebrum begins god-given report, but the result that such doing is very fast, the result that compares direct trade is good, because search engine to like one-way link, such rank is collected what come is fast, most stationmaster feels to inquire inconvenience so, what such doing is easy let stationmaster consider as cheating join, because such inquiry is no-go, unlike straight contact joins into the other side the connection that can see he stands is checked easily, anyway aught has the one side of its advantages and disadvantages!

交叉连接二是：双方都做交叉连接，互相推广对方需要推广的关键词，如 A B C D 站，A B 站是我的站点， C D站是对方站点，首先是我用A站放对方C站连接，对方用D站连接我的B站，这样的做条件是我的A站的质量如pr要求和对方的D站的条件是平衡的，这样我们才做连接有意义了，简单来说这样的目的是我们在帮对方推广他的C站的排名，对方在推广我们的B站的排名，其实都是互利的，好多没有做过交叉连接的朋友，只要稍微给他们转下弯，他们就糊涂了，这样的确是点是大脑开始难得反映，但是这样做的效果很快，比直接交换的效果好，因为搜索引擎喜欢单向连接，这样的排名收录都来的快，大多数站长觉得这样查询不方便，这样做的容易让站长认为是在骗连接，因为这样的查询是不方便，不像直接点进对方连接能看见自己站的连接容易检查，反正任何事物都有它的利弊的一面吧！
