At every stage, clockmakers led the way to accuracy and precision; they became masters of miniaturization, detectors and correctors of error, searchers for new and better.
在每一个阶段,钟表匠都引领着通向精确和精密的道路;他们成为微型化的大师,错误的探测器和纠正者,追求更新和更好。
Precision measurements of this sort are fraught with difficulty and other sources of error may have crept in.
这一类精密测量总是有许多困难,一些人们未曾预料到的其他误差源可能影响结果。
The standard limit on the precision with which a quantum measurement can be carried out is due to the statistical error associated with counting discrete particles rather than continuous quantities.
量子测量中精度的标准极限,源于与可计数离散粒子,而不是连续量相关的统计误差。
