英語でSHADOW BANDSはどんな意味ですか？
影のバンド
シャドーバンドは、明るく暗い交互の薄い波線であり、全日食の直前と直後に平らな色の表面で並行して動いて起伏することが見られます。 それらは、地球の大気を照らしている薄いスロット状の太陽の三日月によって引き起こされます。彼らの動きは大気の風によって引き起こされます。 2008年、スチュアート・イブス博士は、超音速で走行している月の影を含む超低周波騒音によってシャドーバンドが発生する可能性があることを示唆しました。 このことから、彼は理論化して、月の動きは影の前に衝撃波を作り、それが影のバンドを引き起こす。 エヴァス博士は、「実証されれば、日食は光学的現象だけでなく音響的現象でもあるという啓示のようなものになるだろう」と述べた。 ブライアンジョーンズ教授は、「この理論は機能し、代替手段を探す必要はない」と述べた。 シャドーバンドは歴史のなかで注目されています：▪9世紀のADのシャドーバンドは、初めての日食であり、古くからのアイスランドの詩的なエドルダの一部であるヴォルスパで初めて説明されています。
英語辞典でのshadow bandsの定義
辞書のシャドーバンドの定義は、太陽の日食の全体の直前と直後に、地球上の明るい色の表面を横切って移動するように観察されるゆっくり動く波の光と暗い波です。 それらは、不規則な大気屈折の影響から生じると考えられている。
