随着对重力测量精度要求的逐步提高,对各种误差的研究日渐深入,正确了解重力测量结果中各类误差的性质、来源、量级以及如何加以改正都是十分重要的问题。许多文献表明,当前各类误差中第一类半系统误差数值最大,它主要是由重力仪格值的误差引起的。而重力仪格值的误差在格值测定时就存在,这是由于重力仪自身的性能以及受外界因素的影响,使仪器格值发生波动和改变,从而增大了格值的误差。目前,我们还没有办法解决由重力仪自身性能所造成的仪器格值的改变,但受外界因素的影响,可通过一定的方法加以改善,现就温度变化对重力仪格值的影响作一简述。
With the gradual increase of the requirements for the precision of gravity measurement, the research on various errors is becoming more and more in-depth. It is very important to correctly understand the nature, source, magnitude and how to correct the errors in gravimetric measurement. Many literatures show that the first type of semi-systematic error in the current types of errors is the largest, which is mainly caused by the error of the gravimeter’s value. However, the error of the gravimeter gauge value exists when the grid value is measured. This is due to the performance of the gravimeter itself and the influence of external factors, which cause the instrument grid value to fluctuate and change, thus increasing the grid value error. At present, we have not got any solution to the change of the instrument grid caused by the performance of the gravimeter. However, due to the influence of external factors, we can improve it by some methods. Description.
