摘要
分析了羊八井宇宙线强度的气压修正,分析表明,气压修正不仅与气压有关,而且与太阳活动有关。太阳活动最高的年,气压修正系数的绝对值最大。此外,计数率的修正值还与数据采样的时间间隔有关,即使是同一时间段,不同时间间隔采用率得到的修正值是不同的。本文最后分析了西藏羊八井中子监测器观测数据的气压修正,得到单路及八道多重计数的气压修正系数。
In this paper, the pressure correction of the cosmic ray intensity in Yangbajing is investigated. Pressure correction is not only related to the atmospheric pressure, but also to the solar activities. The absolute value of barometric coefficient is biggest when the level of solar activities is highest. And the barometric coefficient is related to the sampling time of data. In the same time, using different sampling time got different barometric coefficient. The pressure correction is made to the raw data of Tibet neutron monitor, and the barometric coefficients of single channel and eight multiplicity channels are calculated.
