Both the belayer and climber ( who asked that their names not be used ) , described hearing a loud pop !

据保护员和攀爬者（当事人要求不透露他们的真实姓名）描述，那一刻他们听到砰地一声！

First : the position of the first bolt invariably leads to a greater angle in the rope as the belayer stands away from the vertical plane .

第一：因为保护者站在离开岩壁的地方，第一把快挂总是导致通过它的绳子弯曲成很大的拐角。
