简述图根导线测量外作业工作中的注意事项。

答案

参考答案：（1）布设和观测图根导线控制网是测量的基础，为避免出错，应严格按照测量规范的要求进行工作。（1分）（2）布设和观测图根导线控制网，应尽量与测区内或附近的高级控制点连接，以便求得起始点的坐标和起始边的坐标方位角。若测区内没有高级控制点，则建立独立的控制网，用罗盘仪测起始边的磁方位角为坐标方位角，并假定起始点的坐标。（2分）（3）城市地区图根导线测量，图根点应设在道路交叉口、胡同口、主要建筑物附近等处。为了避免干扰和提高效率，可在夜间进行观测。（1分）（4）进行图根导线测量时，当选好导线点后，最好先画出图根导线草图，根据导线草图确定测角时应测的角度，避免出错。（1分）

Is money everything? At present some people think that        is everything. Some of them even        their lives for it. Money has its most useful        on the poor, but once a person has a rich life, a lot more money doesn't mean more       .
