英語でVAN ALLEN BELTはどんな意味ですか？
ヴァンアレン放射線ベルト
ヴァンアレン（Van Allen）放射帯は、惑星の磁場によって惑星の地球の周りの所定位置に保持される、少なくとも2つの高エネルギー荷電粒子の層の1つである。 ベルトは、地表の放射線レベルが変化する表面よりも約1,000〜6万キロ高い高度から伸びている。 ベルトを形成する粒子の大部分は、宇宙線によって太陽風および他の粒子から来ると考えられている。 ベルトは、発見者、ジェームス・ヴァン・アレンの名前をつけられ、地球の磁気圏の内側に位置しています。 ベルトは、内側ベルトを形成する外側ベルトおよび陽子と電子の組み合わせを形成するエネルギーの高い電子を含む。 放射線ベルトは、アルファ粒子のような他の核をより少量含んでいる。 ベルトは衛星を危険にさらします。衛星は、軌道が放射帯にかなりの時間を費やしている場合、適切なシールドで敏感な部品を保護する必要があります。 2013年、NASAはVan Allen Probesが一時的な第3の放射帯を発見したことを報告した。これは太陽からの強力な惑星間衝撃波によって破壊されるまで4週間観測された。
英語辞典でのVan Allen beltの定義
辞書のVan Allenベルトの定義は、地球上の荷電粒子の2つの領域のうちの1つであり、内側のものは地球上の2400〜5600キロメートルから延び、外側のものは13,000〜19,000キロメートルである。 荷電粒子は宇宙線に起因し、地球の磁場に閉じ込められます。
