You've irreversibly changed that substance because you've changed the structure of all the proteins inside.

蛋白质的结构发生不可逆的变化,因为蛋白质内部的全部结构都改变了

OK, we're going to do this reversibly, which means we're going to slowly change the external pressure very, very slightly at a time, so that at every point we're basically in equilibrium, p2/ until the pressure reaches a new smaller pressure p2.

整个过程保持可逆，外界压强,变化得很慢，每一个瞬间,都保持平衡，直到压强减小到末态值。
