The Pitons的意思|示意

These days, Mr. Breashears is still climbing the Himalayas, but he is lugging more than pitons and ice axes.

这些天，布里·谢斯先生还在攀登喜马拉雅山脉，但他带上的不仅仅是岩钉和冰斧。

He had no ropes, bolts or pitons, and preferably no knowledge of the ascent except what he had gleaned from the ground, telling himself "Dude, there's some holds here, man."

他不带绳索、钢锥或岩钉。除了在地面上的观察判断所得，他并不喜欢实地了解岩壁各处的状况。

The tests are like pitons, assuring you that no matter what happens, once you have made progress, you can only fall so far.

测试就是岩钉一样，保证不管发生了，一旦取得了进展，就会固定已有的进展。
