Unlike other spacecraft, it can act as an antigravity machine, using solar pressure to balance the Sun's gravity and thus hover anyplace in space.

不同于其它航天器，它可以作为一个反引力器，利用太阳风的压力平衡太阳的引力，从而使飞船停留在太空中的任何地方。

Instead of pumps, valves and human operators, the plant USES airflow, pressure changes and gravity to gradually cool the reactor.

这家电站没有使用管道、阀门和人工操作，而使用了气流、压力变化和重力来逐步冷却反应堆。

Fusion in a star's core produces heat and outward pressure, but this pressure is kept in balance by the inward push of gravity generated by a star's mass.

恒星核心中发生的核聚变产生热能与向外的压力，不过这份压力由恒星质量所产生的内向重力抵消了。

At that speed, the pressure is three times the force of gravity.

Normal matter, which is mostly gas, has pressure and that resists gravity.

Over the past two years, al Qaeda has shifted its center of gravity from the Afghanistan-Pakistan border region where it is under pressure from drone strikes toward the Arab world, green-lighting the return of dozens of Arab operatives to their homelands, according to Western intelligence officials.
