【简答题】精密水准测量时,在两相邻测站上,应按奇、偶数测站的观测程序进行观测,对于往测奇数测站按( ),偶数测站按( )的观测程序在相邻测站上交替进行。返测时,奇数测站与偶数测站的观测程序与往测时( ),即奇数测站由( )开始,偶数测站由( )开始。这样可以消除或减弱与时间成比例均匀变化的误差对观测高差的影响,如( )和仪器的( )等影响。
【简答题】设 是某8元齐次线性方程组的基础解系,则该方程组系数矩阵的秩为( )
【判断题】在两相邻测站上,应按奇、偶数测站的观测程序进行观测。对于往测奇数测站按“后前前后”,偶数测站按“前后后前”的观测程序在相邻测站上交替进行。返测时,奇数测站与偶数测站的观测程序与往测时相反,即奇数测站由前视开始,偶数测站由后视开始。这样的观测程序可以消除或减弱与时间成比例均匀变化的误差对观测高差的影响,如i角的变化和仪器的垂直位移等影响。
