In addition, video and audio feeds are extremely costly to store due to the large volumes of this type of data collected, coupled with its poor compression characteristics.

此外，视频和音频记录的存储成本非常高，因为此类数据的量很大并且不能有效地压缩其体积。

Increase the compression degree can make arc of high temperature plasma jet extended, form more uniform high temperature area, and increase the speed of the jet, can reduce the width of the poor.

增加电弧的压缩程度可以使高温等离子射流延长，形成更为均匀的高温区域，同时加大射流的速度，可以减小切口上下的宽度差。

The on-the-wire encoding of CORBA contains a large amount of redundancy, but the protocol does not support compression. This leads to poor performance over wide-area networks.

CORBA的线上编码包含大量的冗余，但是协议并不支持压缩，这导致了大面积网络的性能缺陷。
