The Solar Probe Cup will scoop up bits of the sun’s corona and solar wind to continuously measure its speed, temperature and density.
太阳探测杯(The Solar Probe Cup)会收集一些日冕和太阳风去持续地测量速度、温度和密度等数据。
Same would go for steel and memory chips among older industries, and solar cells, wind turbines and high-speed trains among new industries.
在一些比较老旧的行业如钢铁、记忆芯片,在新兴的行业如太阳能电池、风力涡轮机、高速铁路等,情况也是一样的。
Hydrogen atoms are more abundant than either helium or oxygen but their low mass means they are easily swept aside by the high-speed solar wind and can’t readily be detected.
福斯勒指出氢原子数量比氦原子或氧原子数量要多得多,但是它质量很小,很容易被太阳风吹散,从而不能被稳定地观测到。
