microgravity

Microgravity conditions aboard the space station allow researchers to observe fluid dynamics without terrestrial interference.空间站上的微重力条件使研究人员能够在没有地球干扰的情况下观察流体动力学。

Long-duration exposure to microgravity causes bone density loss that must be countered with targeted exercise regimes.长期暴露在微重力环境中会导致骨密度流失，必须通过有针对性的锻炼方案来抵消。
