Costs and benefits of marginal changes will be clearer: small Australian miners, for example, will have more incentive to build capacity.

边际变动的成本与效益将更为清晰：比如澳大利亚的小型矿商将有更大动力构建产能。

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。

Recently installed systems tend to have excess capacity, and since the immediate marginal costs of using them seem to be negligible, management often encourages new uses.

最近安装的系统倾向于有超量能力的趋势，而由于使用它们的即时边际成本似乎可以忽略不计，管理层常鼓励新的使用。

Yet each firm has sunk so much capital in plants that it is strongly tempted to use the capacity to build extra cars that fetch enough revenue to cover marginal costs in the short run, but not total costs in the long run.
