| 摘 要： | 根据SS-Y伸缩仪的原理,从理论和实际观测分析了气压变化对伸缩应变观测日变曲线的影响及两者间的相关性。分析表明,应变观测值波动与气压变化呈正比例关系,也就是说两者之间是正相关。因此认为气压变化是伸缩仪观测日变曲线畸变的主要因素之一。为减小气压变化对观测的影响还对台站仪器架设提出了几点改进建议。

| Abstract: | According to the principle of SS-Y tensometer,We analyze the influence and relation of air pressure change toward observational daily change curve of tensometer.The result shows,the relation between strain observational and air pressure is direct ratio.So,we think air pressure change is one of the main factors of aberration of observational daily change curve of tensometer.In the end,we advance some advises for putting up the apparatus in seismic station. |
