例如我们易于理解为什么,当试图测量一个不可逆系统的总能量,给出的或许。
I mean we can, we can sort of understand why OK, the total energy, if we measure it, we measure a process which is not reversible.
一点提示,不可逆过程中系统,对外界做的功,总是小于,之前我们。
Wirr Minus w irreversible, this is the work which is done to the environment by the system, -Wrev minus w irreversible is always smaller than minus w reversible.
所以为了能够使用能力并保证系统安全,根进程必须能够不可逆转地将它的uid切换到非0,同时保留一些能力。
So in order for capabilities to be useful, a root process must be able to irrevocably switch its uid to non-zero while keeping a few capabilities.
I mean we can, we can sort of understand why OK, the total energy, if we measure it, we measure a process which is not reversible.
例如我们易于理解为什么,当试图测量一个不可逆系统的总能量,给出的或许。
Because if it's irreversible, it's very likely that I don't know what the pressure inside the system is doing while this is happening.
因为对不可逆过程,系统内部的压强,没有明确的定义,气体不处于平衡态。
So w, the work is less for the irreversible process than the reversible process.
不可逆过程中系统对外界,做的功要比可逆过程时小。
