The Method based on the DCT transformation has been the center technology for most of the digital image and video coding standards, since it features on good de-correlation and energy compression.

基于分块dct变换的编码方法，由于具有良好的去相关性和能量压缩特性，已经成为现有大多数图像和视频编码标准的核心技术。

The chemical steps in the capture consume energy, as do the compression and transport of the carbon dioxide.

碳捕获过程中的化学处理过程需要能量，压缩和运输二氧化碳同样需要能量。

But you need so much energy for capture and compression that coal as a fuel, the entire idea of a coal fired plant, becomes uneconomic.

In existing CAES systems energy is lost as heat during compression, and the air must then be reheated before expansion.
