伏特

Micro-voltmeter Capable of measuring either alternating or direct current voltage within an accuracy of 2%.

能测量交流或直流电压在精确度2%之内的微型伏特表。

However, in spite of all this similarity between a voltmeter and an ammeter there are also important differences.

可是尽管伏特表与安培表之间有这些类似之处，但还有若干重要的差别。

The units in which we show voltage and current are volt and ampere respectively.

我们用以表示电压和电流的单位分别为伏特和安培。

One volt will cause a current of one ampere to flow through a resistance of one

欧姆是电阻单位。1伏特的电压通过1欧姆的电阻能产生1安培的电流。

The accepted formula for a Sling is " a Collins sweetened with both sugar syrup and a flavoured liqueur". Slings occasionally have bitters and/or egg white added to the recipe, although this is less common with Slings than with sours, fizzes or Collinses. For rum-based Slings, many prefer Angostura bitters; for gin, vodka and brandy-based Slings orange bitters are a popular choice; for bourbon-based Slings peach bitters are said to be the most fitting. Many people prefer Slings made with lime juice.

大众通常接受的司令是含糖浆的利口考林斯，司令的配方里偶尔含苦精或蛋清，虽然这已经不如菲士或考林斯用的频繁，以朗姆为配方的司令，更青睐安格斯图拉苦精；金酒，伏特加，白兰地为配方的司令会选择橘子苦精；波本为配方的司令，似乎更适合用蜜桃苦精；也有许多人更喜欢莱姆汁配的司令。

Different DNA constructs were introduced into the decapsulated cysts of Artemia by electroporation under 2KV, 20 μsec pulse length, 20 number of pulses and a DNA concentration of 20μg/μl in a volume of 100μl.

不同的构筑质体经由电穿孔法，被导入经去壳处理后的丰年虾休眠卵中，在2千伏特、20微秒的脉冲波长度、20次的脉冲数和在100微升的体积中DNA浓度为每微升20微克的设定条件下。

T, Beefeater, Kahlúa and Malibu in 2005, and most recently Absolut vodka to the already strong brand portfolio.

随着2005年百龄坛、玛姆、巴黎之花、必富达、甘露和马利宝，以及最近绝对伏特加等品牌的加入，公司强大的产品组合得到不断丰富。

In the Reggie Belafonte story,|and who could blame us?

巴勒伏特的事情更感兴趣|这也不能怪我们吧？

The party needs to be perfect, so blood orange martinis or beluga and belvedere?

这次的生日派对一定要办得完美，那是选血橙马天尼酒还是白鲟鱼鱼子酱和雪树伏特加？

电路 2 电路或电网络由以某种方式连接的电阻器，电感器和电容器等元件组成。如果网络不包含能源，如电池或发电机，那么就被称作无源网络。换句话说，如果存在一个或多个能源，那么组合的结果为有源网络。在研究电网络的特性时，我们感兴趣的是确定电路中的电压和电流。因为网络由无源电路元件组成，所以必须首先定义这些元件的电特性。就电阻来说，电压-电流的关系由欧姆定律给出，欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。在数学上表达为： u=iR (1-1A-1)式中 u=电压，伏特；i =电流，安培；R =电阻，欧姆。纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到：U=Ldi/dt 式中 di/dt =电流变化率，安培/秒； L =感应系数，享利。电容两端建立的电压正比于电容两极板上积累的电荷 q 。因为电荷的积累可表示为电荷增量 dq 的和或积分，因此得到的等式为 u=，式中电容量 C 是与电压和电荷相关的比例常数。由定义可知，电流等于电荷随时间的变化率，可表示为 i = dq/dt。因此电荷增量 dq 等于电流乘以相应的时间增量，或 dq = i dt，那么等式(1-1A-3)可写为式中 C =电容量，法拉。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
