【摘要】 对黄陵柏树样本年轮与太阳黑子数年平均水平的周期分析结果表明:两者的周期变化一定程度上存在着一致性,除著名的11.0年Schwable周期外,还存在200～300年,98年左右、56～60年、42～43年、8.4～8.5年、5.6～5.8年的相似变化周期。对这—现象的自然机制进行了探讨。更多还原

【Abstract】 The tree rings of the Huang Ling Cyprcss sample and the annual average sunspots number were analysed. The results show that there is the resemblance between their periods. Besides the well-known schwable period(11.0 years), there are similar periods of 200～300, ～98, 56～60, 42～43, 8.4～8.5, 5.6～5.8 years. The natural meehanism, which lead to this phenomenon is discussed briefly.更多还原
