高差是两点间高程之差，即终点高程减起点高程。用高程测量方法测出未知高程的点时，先从已知高程点测出两点的高差，再计算出未知高程点的高程。未知点比已知点高，两点的高差为正，反之为负。

Based on the analysis of experimental data we found that the quality and accuracy of the baseline are affected not only by the geodetic difference but also by the length of the baseline.
通过对实验数据的分析发现,基线的质量和精度既与基线两端的高差有关系,又与基线长度有关系,因此其主要是受基线的倾角的影响。
