再举一个电力方面的例子，早在1900年，交流电标准发布以来，成千上万的小型电力公司合并成了大型的控股公司。
Or electricity. In the early 1900s, after the standardization to alternating current distribution, hundreds of small electric utilities were consolidated into huge holding companies.
选择交流电作为工业标准的原因很简单，在早期供电距离很短的电网里，交流电的损耗比直流电小。
The reason was that over the short distances spanned by early power grids, AC transmission suffers lower losses than DC. It thus became the industry standard.
交流电传动技术的不断成熟，使其真正成为所有新机车动车的标准。
With its high maturity three-phase ac drive technology has become the standard for practically all new vehicles.

此标准的设计目的是：降低敏感设备对来自交流电源的电涌及长时延过电压的敏感性。
This standard was designed to reduce the susceptibility of their sensitive equipment to AC power line transients and long duration overvoltages.
在GB 3 667 - 1997《交流电动机电容器》标准中对绝缘电阻无专项要求。
No requirements regarding insulation resistance are stipulated in GB36671997 The Capacitors for ac Motors.
但是一些人却在质疑这个标准，因为从远距离传输来看，高压直流电缆损失的电量比交流电缆少。
Some people, however, question that standard because over long distances high - voltage DC lines suffer lower losses than AC.
从而使单向可控硅在交流电力变压电路中使用简单化、标准化。
Therefore, application of the single-direction thyristor in AC electric transformer circuit becomes of simplification and standardization.
