本文根据多台CG—2型重力仪在不同基线场标定的格值资料,分析了调测程对格值的影响,讨论了导致格值变化的原因。认为由于各台仪器石英系统的弹性性能不可能完全相同,仪器格值亦各自有别;在相同重力段差区间调测程时,各台仪器弹性性能的变化将有所差异,每台仪器的格值变化也就各不相同;格值变化较大的某些仪器(或测程变化超过一定的范围)不同测程范围与格值之间可能存在着线性变化关系。
Based on the grid data of multiple CG-2 gravimeters calibrated in different baseline fields, this paper analyzes the effect of the tuner on the grid values and discusses the reasons leading to the grid values variation. It is considered that the elastic properties of quartz instruments in each instrument may not be the same and the values of the instruments are also different. In the same gravimetric difference interval adjustment program, the elastic properties of each instrument will vary. For each instrument The value of the change will vary; some of the larger cell values ?? change (or range over a certain range) There may be a linear relationship between the range and the grid values.
