| 摘 要： | 在检测测距仪的周期误差中,发现有些仪器的周期误差含有明显的二次谐波分量,因此应加入二次谐波因子进行平差计算,以求得正确的结果。本文首先概述平差的数学模型,然后利用数理统计中假设检验的方法,推导了判别周期误差是否显著的公式,最后利用BASIC语言编制了计算程序。

SECOND-ORDER HARMONIC WAVE ANALYSIS FOR THE PERIODIC ERROR OF DISTANCER THROUGH MULTIVARIATE LINEAR REGRESSION ANALYSIS |
| |
| Abstract: | In the detection to the periodic errors of some distancer,the second-
order harmonic wave element is obviously found in the error.In order
to correct the result,the second order harmonic wave factor must be
added in the adjustment.
In this article,the mathematic is model of the adjustment briefly int-
roduced first,then,the determination formula for the periodic errors is
deduced and the corresponding computer program in BASIC is work out. |
