温度不均匀对液体静力水准仪精度的影响

利用液体静力水准仪对建筑进行沉降观测， 可以获取很高的观测精度， 但由于温度不均匀， 造成液体密度不均匀， 使高差测量产生较大的误差， 因此有必要研究温度对高差测量的影响，并找出减弱的措施， 本文对此做了一些初步研究。

When hydrostatic level in measurement of settlement is used,very high precision can be obtained,however,because of the temperature gradients causing the density gradients,there are some big errors in the measurements of elevation difference.Hence,it is necessary to study the influence of temperature gradients and to find out the weakening methods.
