Astrophysicists working with ground based detectors at the South Pole 你理解的错误在于你把Astrophysicists working with ground based detectors和at the South Pole 分割开了其实at the South Pole 是修饰detectors的，也就是修饰Astrophysicists working with ground based detectors 这句话的核心主语是detectors，你翻译的“在南级使用基地探测仪”主语省略了，谓语是“使用”，宾语是“基地探测仪”这明显跟这句的含义不同了，按你的翻译，应该是，Use the Astrophysicists working with ground based detectors at the South Pole
