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。
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.
本研究的目的就是在异步通信网络环境中，采用连续的时间戳通信模型，并利用时钟精度差概念和小波除噪算法实现系统中各个计算机之间的自适应时钟同步。
The continuous time-stamp communication model and the wavelet technology were applied to evaluate running precision difference of clocks, in order to reduce the effect of network delay efficiently.
