1. In part because, while the NAIRU and the output gap are nice ideas, it is often hard to agree, at any given moment, on the value of either number.
   部分原因在于，虽然自然生产率和经济产出缺口是一个很不错的想法，但往往难以随时使两者数值匹配。
2. The installation of an air gap and drain line are recommended.
   建议安装气隙和排放管道。
3. This would create an air gap to eliminate any possible backflow.
   这将产生一个气隙以消除任何可能的回流。
