摘要
利用小波变换,结合折叠周期分析方法,对羊八井宇宙线观测站TibetASγ阵列1997年11月到1998年6月的实验记录数据进行周期分析,发现了气象参量,包括观测面处大气压和室外温度的日变化和半日变化.接下来的关联分析表明:宇宙线流强的周期变化与气压和温度的周期变化显著相关.
We use the technique of wavelet analysis and epoch folding methods to search for the superimposed periodic signals of 1-10TeV cosmic ray in the data obtained with Tibet Ⅱ/HD AS Array for December of 1997 to June of 1998. Solar time semi-diurnal and diurnal variations of meteorological parameters, including the atmospheric pressure and the temperature out of the room are analyzed. The following correlation analysis shows that the obvious correlation exists between the periodic variations of trigger rate and record rate of the cosmic ray observation experiment and of the atmospheric pressure and the temperature out of the room at the level of observation.
