atomic c clock 原子钟
The deeper the C state, the more power saving steps are taken—steps like stopping the processor clock or stopping interrupts from coming in.
CPU 电源状态程度越深，采取的电能节省措施就越多 — 比如说停止处理器时钟或停止外部中断请求。
Similarly, if you run the runclock3.sh script of Listing 4, and press Ctrl-c in the terminal window where the script is running, the script will immediately terminate without shutting down the clock.
类似地，如果运行清单4中的runclock3 . sh脚本，并在运行脚本的终端窗口中按下Ctrl - c，脚本会立即终止，但是没有关闭时钟。
By the way, if you're curious about why racemization is so much less accurate a clock than C-14 for dating a tooth's age, part of the explanation has to do with temperature.
顺便说一下，如果你好奇为什么在判断牙齿年龄方面、外消旋化会比碳14定义的时钟精度差之甚多，那么部分原因与温度相关。
