The detector can detect it and then within 30 minutes a result will come out.

探测器可以探测到它，然后在30分钟内，结果就会出来。

A metal detector can find things like coins, rings, and keys.

金属探测器可以找到硬币、戒指和钥匙等物品。

A little further, at six meters below the surface, we've reached the maximum depth that metal detectors can pick up signals from.

再往下一点，在地表以下六米处，我们已经到达了金属探测器能接收到信号的最大深度。

One such solution is to detect deepfakes via machine-learning methods. While these detectors can be successful in the short term, people looking to evade such systems will likely just respond with better technology, creating a continuing and expensive cat-and-mouse game.

一种解决办法是通过机器学习的方法来检测“深度伪造”。短期内，检测可以奏效。但想要设法避开此类系统的人，很可能会以更强的技术进行应对。这么一来，就会衍生出一场永无止境、耗资巨大的猫鼠游戏。
