根据WIMP的年调制特征，描述和研究了用大质量高放射性比DAMA NaI(TL)装置收集的14962 kg·d的统计结果。对这些数据的最大似然分析，结合以前发表的4549千克·天的统计数据(总统计数据为19511千克·天)，支持在99.6%C.L.存在年调制的假设。
The results achieved with a statistics of 14962 kg·day, collected with the large mass highly radiopure DAMA NaI(Tl) set-up, are described and investigated in terms of WIMP annual modulation signature. A maximum likelihood analysis of these data, combined with the statistics of 4549 kg·day previously published (total statistics of 19511 kg·day), favours the hypothesis of presence of an annual modulation at 99.6% C.L.
