1·What is the unit of potential difference? Volt.

势能差的单位是什么，伏特。

2·Even when technologies have the potential to make a difference, deployment in the developing world often stumbles for lack of infrastructure.

即使当技术具备有改变的潜力时，在第三世界的管控常常由于组织性的缺失而成为绊脚石。

3·Metallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.

比起铅来，金属锡的电正性没有二氧化锡的电负性强，所以无法产生可用的电位差。

4·In the case of lead and lead dioxide, this potential difference is just over two volts per cell.

以铅和二氧化铅为例的电池，每节电池的电位差可产生2伏电压。

5·A second important difference, when it comes to response capacity, is that we now have a wider armamentarium of possible interventions - antiviral medicines in addition to the potential for a vaccine.

第二个重要的不同涉及反应能力，即我们现在已有更广泛的整套可能干预措施——除潜在的疫苗外，还有抗菌药物。

6·The electron volt is not a unit of potential difference.

电子伏特不是，就是一单位的电子伏特。

7·The time of day when you choose to work out can make all the difference when it comes to working out to your maximum potential.

锻炼时间的选择非常重要，因为恰当的时间可以激发你身体里的最大潜能。

8·In other words, the difference in the chemical potential is, this changes as a function of pressure.

换句话说，化学势之差等于，这个差值随着压强的变化。

9·This difference raises questions about the potential role of observational learning in promoting chimpanzee mothers' prolonged transport of deceased young, Biro and colleagues wrote.

这些不同“有助于我们在观察学习中提出有益的问题，以便于了解是什么引起了母黑猩猩长时间地带着死去的幼崽一起行动，”毕罗和他的同事们写道。

10·The resistance of any length of a conducting wire is easily measured by finding the potential difference in volts between its ends when a known current is following.

已知导线中流过的电流，只要测出导线两端电位差的伏特值，就能很容易得出任何长度导线的电阻值。
