摘要
本文根据多年重力监测工作情况,结合拉科斯特重力仪的结构特点,对仪器在观测中的干扰因素进行分析,认为影响仪器观测精度的干扰因素有两类:一类是仪器本身产生的系统误差,如格值误差、零飘及弹性后效等;另一类是外界干扰因素,如振动、温度、人为观测方法不当等,如果在观测中能消除或减小这些干扰因素影响,拉科斯特重力仪就可能达到更高的观测精度。
On the basis of working conditions of mobile gravity observation in these years and the structure characteristics of LCR gravity meter,some disturbance factors in the field observation were analysed in this paper.The analysis shows that there are two kinds of disturbance factors which influences the observation accuracy of LCR gravity meter,One is the system of LCR gravity meter,for example the error of the scale error,zero drift,elestic delay and so on;Another is the outside factors shuch as the viberation,temperature,unsuitable observation method and etc.If these disturbance factors can be elimited or reduced in the fiend observation,LCR gravity meter should achieved a higher observation accuracy
