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。

XRD, Raman spectroscopy, DC four-probe, impedance spectroscopy and SEM were applied to analyze the crystal structure, ionic conductivity and microstructure, respectively.

Carbon nanotubes are used to solve this problem effectively in this project. As controlled DC voltage is applied to the CNTs electrode, the sharp tips of CNTs can generate high electric fields, so it was easy to ionize gas and get larger current at lower voltages.

纳米碳管的出现有效地解决了该问题,在外加直流电压激励下,纳米碳管的尖端会形成很强的非均匀电场,在电压相对较低的情况下能很容易地电离气体且获得较大的放电电流。

For the case in a dc-bichromatic electric field (wB= 0), when one of the ratios is an irrational number, the other is a rational number, the dynamicallocalization always remains.

在直交流外场下,当其中一个比率是有理数,另一个是无理数时,总是保持动力学局域化;当两个比率都是有理数或无理数时,动力学局域化发生在准能带塌缩点。

Mike Gold, director of Bigelow Aerospace's office in Washington, DC, has nothing good to say about the country's export policy:"if the purpose of ITAR is to lose billions of dollars of business, ship jobs overseas, and the Iranians and the Chinese get the same technology anyway, then mission accomplished." The regime, he says, is obsolete and counterproductive.

位于华盛顿特区的Bigelow 宇宙办公室的总裁Mike Gold,他说道美国的出口政策时没什么好话,他说,"假如ITAR的目的是丢掉几十亿美元的生意、将成百万件工作送到国外,以及让伊朗人和中国用某种方式获得相同技术,那么它成功了,它的目的达到了。"
