通过1981年11月到1985年10月对泰安地震台观测山洞抗干扰(温度、湿度、地面振动、空气扰动)的观测实验和研究,取得如下结果:利用逆温和露点原理,有效地建立起一套压低洞内湿度的措施,增加了温度的稳定性;减弱了山洞内微气流扰动;证实了一定的环境地面振动,对观测精度无影响。从而提高了仪器观测质量;为观测数据的处理提供了一些定性和定量的依据。此外对长期处于半密封条件下的山洞内空气污染,也进行了几次取样测定,提出了一些看法。
Observations and experiments on the observation of cave anti-interference (temperature, humidity, ground vibration, air disturbance) in Tai’an Seismic Station from November 1981 to October 1985 have the following results: Using the principle of inverse temperature and dew point, Set of measures to reduce the humidity in the cave increases the temperature stability; weakens the micro-airflow disturbance in the cave; confirms certain environmental ground vibration and has no influence on the observation accuracy. Thereby improving the quality of the instrument observation; provided some qualitative and quantitative basis for the observation data processing. In addition to long-term semi-hermetic conditions in the cave air pollution, but also carried out several sampling determination, made some observations.
