Bicycles and perhaps skates may be run by jet power, and a new thing to ride may be a small flying saucer.

自行车或许溜冰滑板可能由喷气动力推动。一种新型的可开的东西可能就是一个小飞碟。

On its return journey the aircraft could then transition back to jet power and land like a traditional jetliner on a conventional runway.

返还地面时，这种引擎还能“变回来”，用传统的喷气动力让飞机在普通跑道上降落。

Also, the experiments had been carried out to study the effects of the high-pressured water jet power, the amount and composition of grinding medium and the impact time on the comminuting capability.

通过试验方法研究了高压水射流功率、研磨介质的填充量和配比、冲击时间等对该装置粉碎能力的影响。

It would also need to be only half the size of a conventional jet of similar power, says Dr Lior.

That impressive streak could have been, but was thankfully not, broken on Thursday when a bird strike apparently caused both engines on a US Airways jet to lose power.

The fire started after a battery in the jet's auxiliary power system overheated.
