After the drilling was completed, Perseverance took additional pictures of the sample as well as the tube it was kept in.

在钻孔完成后，" 毅力号" 拍摄了样品以及保存样品的试管的额外照片。

But instead of just being one very tall tube, it was engineered as nine different tubes bundled together.

但它不仅仅是一根非常高的管子，而是设计成九根不同的管子捆绑在一起。

[Ryan] If it is a fruit, why did they think it would be a good idea to tube it?

- [Ryan] 如果它是一种水果， 为什么他们认为用管子装它是个好主意？

When the action potential travels down one of those tubes, it eventually triggers the voltage-sensitive proteins that are linked to those calcium channels on the cell's sarcoplasmic reticulum.

当动作电位通过其中一个管子时，它最终会触发与细胞肌浆网上的钙通道相连的电压敏感蛋白。
