| 不可再生能源 | non-renewable energy resource Non-renewable resources have been built up or evolved over a geological time-span and cannot be used without depleting the stock and raising questions of ultimate exhaustibility, since their rate of formation is so slow as to be meaningless in terms of the human life-span (非再生能源是在地质时间跨度上已建成或进化而成的，如果没有消耗储备将不能使用，同时提出了最终耗竭问题，因为它们的形成速度如此缓慢以致于对于人类生活跨度而言毫无意义。) |
| 不可再生资源 | non-renewable resource A natural resource which, in terms of human time scales, is contained within the Earth in a fixed quantity and therefore can be used once only in the foreseeable future (although it may be recycled after its first use). This includes the fossil fuels and is extended to include mineral resources and sometimes ground water, although water and many minerals are renewed eventually (就人类历史时间尺度而言，地球中含有固定数量的自然资源，因此在可以预见的将来仅能被使用一次(尽管它可能在第一次使用后被再利用)。这包括化石燃料和扩展到包括矿产资源、有时也包括地下水，虽然水和一些矿物质最后将被更新。) |
| 不可逆转性 | irreversibility of the phenomenon That quality of a process that precludes a prior state from being attained again (一种过程特性，在该过程中不可再次回到已经执行过的某个过程状态。) |
