在高层及超高层建筑工程中，测量基准传递和轴线、垂直度、高程控制是建筑物施工质量控制的重点内容之一。
The transforming of survey datum and the control of axis, vertical level, elevation are of great importance on controlling quality of high-rise building construction.
结果表明，LDA探头非垂直布置时，测量控制体具有与垂直布置时不同的性质。
The results show that the measurement volume with off-axis of the LDA-probe has different performance from that with on-axis probe.
