While the actual wattage difference between a 1 TB SATA drive and a 300 GB Fibre Channel drive is marginal, the cost difference on a watt-per-capacity basis is significant.

虽然1TB SATA驱动器和一个300 GB的光纤通道驱动器的实际功率差异相差不远，但瓦特/容量（单位容量的能耗）的成本差异极大。

With the increasing number of modulation formats and the increasing similarity of the induced marginal distributions to a Gaussian channel, the problem is becoming more and more challenging.

随着现代通信系统中采用的调制模式不断增多和高斯信道感应边缘分布的相似性不断增加，该课题的研究越来越具有挑战性。

The main reservoir sedimentary facies is channel fill formed by channel detention and marginal bank.

And the reason is that when the channels are bundled so that the cable subscriber has to purchase the lot of them, that gives them the option of discovering something that they might not have known before, which is that by surfing around and happening upon a marginal, new, upcoming channel they might find that they like it and they might start watching it.
