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。

So, we think air pressure change is one of the main factors of aberration of observational daily change curve of tensometer.

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。

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.

但是天文学家辛苦分析这些观测金星凌日的探险活动的结果。

But astronomers laboured hard to analyse the results of these expeditions to observe Venus transits.
