摘要
精密水准折光改正涉及到温度垂直分布函数中的参数c。本文通过试验数据分析了实际c值及其变化，由此证实经验c值直接限制折光改正的准确性。
: The cotrection for refraction in precise leveling involves parameter
C contained in the vertical distribution function of temperature. Actual values of
parameter C and its variations are analysed based on experimental data. It is veri-
fied through the analysis that the experimental value of C limits the accuracy of
the correction for refraction in a straightforward way.
