As demand for goods increased during the COVID pandemic, so did the demand for energy to transport those goods.

随着新冠疫情期间对商品的需求增加，运输这些商品的能源需求也随之增加。

So why is the relationship between amplitude and energy transport so important?

那么为什么振幅和能量传输之间的关系如此重要呢？

Intensity, for example, is the energy transported by the light per unit area, over time.

例如，强度是 光在单位面积上随时间传输的能量。

Jin said Pakistan has a great potential in the infrastructure sector, especially in energy, transport, electric power, sea ports, urban development and water supply.

金立群表示，巴基斯坦在能源、运输、电力、海港、城市发展和供水等基础设施领域有巨大的潜力。

One last important measurement of delivering energy is intensity, which is the energy transported by a wave per unit time, per unit area.

最后一个重要的测量是提供能量密度，它是每单位时间、每单位面积在波中传输的能量。
