This paper presents the working principle of the Water Column type PneumaticGauge developed by the author and also the relationship between the indicated pressureand the measuring clearance, pneumatic amplification ratio and the principle of its(?) djustment, the total amplification ratio of this instrument; and finally the working principle of the weight type pressure stabilizer used by this instrument.The last paragraph of this paper discusses the accuracy of this instrument, pointing out its main error is non-linearty and it increases remarkably with decrease inamplification ratio. But because the main variable of this instrument is flow rate,indicated pressure is very low, in the measuring range non-linear error can be neglected. Finally, the accuracy of this instrument may be expressed as a function of theamplification ratio.

本文介绍了作者研制的水柱式气动量仪的工作原理、指示压力与测量间隙之间的关系,气动放大倍率及共调整原理、仪器的总放大倍率;最后介绍了重锤式稳压器的工作原理。本文最后介绍了本仪器的主要精度指标,指出它的主要误差是非线性误差,而且随放大倍率的减少而显著增加.但由于本仪器的主要测量参数是流速,指示压力很低,在测量段上非线性误差很小。本文最后指出本仪器的精度与放大倍率的关系。本文曾经1978年10月在汽车学会第二届年会宣读。

In this paper, the quality of data from seismo-gravity repeatedmeasurements of SSB in 1978-1983 is evaluated comprehensively. By adjustment processing and statistical analysis for the observations of gravity differences, it is indicate that the accuracy of gravity differences observed with 2-4 quartz spring gravimeters (Worden CG_2) can reach 10-20 (10~(-8)m/sec~2) for gravity networks and 25 (10~(-8)m/sec~2) for a line. The accuracy of mean gravity difference observed by 2 gravimeters has increased by 20 per cent as compared with that of single gravimeter and of 4 has increased by twice times separately. It is found from the statistical analysis for observations that the systematic error is no notable especially, the systematic error can be decreased using the mean values of multi-instruments, but the differences between two gravimeters show the same symbol accumulation for S-N measuring line. The gravity differences measured by different survey groups along the same measuring line is difference, and the difference increase with the accumulation of gravity differences sometimes.The comparison between the absolute and relative gravity observations show that there are bigger deviations in the values of a few absolute gravity points

本文对1978—1983年国家地震局地震重力重复测量资料的质量进行了综合评述。通过对观测段差的平差处理和统计分析,表明用2-4台Worden、CG_2重力仪进行重复测量的段差精度:测网可达10-20(10~(-8)米/秒~2),独立测线可达25(10~(-8)米/秒~2)。两台重力仪观测段差的平均值精度比单台仪器提高20%,四台仪器提高一倍。多期观测段差在剔除一些异常变化后,其平均值精度可达10(10~(-8)米/秒),平差后的点值中误差一般小于30(10~(-8)米/秒~2)。 统计分析表明:段差系统误差不显著,特别是多台仪器平均值能削弱系统误差,但南北测线台差出现同号积累。在相同测线上不同单位观测的段差差值有时会随重力差的增大而增大。 本文对部分绝对重力观测值和相对重力测量果结进行了比较,发现少数绝对重力点的值存在较大偏差。
