bench-mark是什么意思

网络释义

用法例句

±12 L~(1/2) is adopted as "the dual tolerances" in repetition measurement of the basic benchmark of a hydrometric station in China,which means ±12 L~(1/2) is not only the tolerance of round-trip survey elevation difference values,but also the tolerance between the new and old elevations after the measurement.

我国水文行业复测水文站的基本水准点采用±12 L~(1/2)作为"双重限差",也就是把±12 L~(1/2)既作为往返测量高差不符值的限差,又作为复测后新老高程之差的限差,这是个大误区,前者的限差是±12 L~(1/2),后者的限差应为±20 L~(1/2)。
