3)  quasi periodicity
准周期性

Based on the historical climate records of China, the study reveals that quasi periodicity is the basic feature of regional dry-wet climate happening in the eastern part over the past 1000 years; difference in the phase of major periods on dry-wet between the north and south of eastern China is displayed in the time-dependent pattern of rainfall, i.
对中国历史气候记录的研究表明:准周期性是过去1000年间中国东部各区域的干湿气候变化的基本特征;各区域间主要周期变化的位相差异,表现为降水的空间分布格局(如南涝北旱、北涝南旱等分布型)随时间的变化;1000年来干湿气候发生过多次十年和百年尺度的突变,降水的突变对农业生产会有明显影响。

补充资料:准周期性
分子式:
CAS号:

性质:引入了一定近似性以后由原严格周期性约化而得的近似周期性。如属立方晶系的A型分子筛,其严格基本周期或晶胞参数α=2.464nm,对应化学式为Na96[A196Si96O384]·216H2O,若将硅铝酸根中处于配位四面体中心的硅或铝原子看作硅、铝各占一半的统计原子(Al0.5Si0.5),则结构可约化而用体积只有原晶胞1/8的准晶胞来表达,其相应准晶胞周期是原周期的一半,即有α′=1.232nm,相应的化学式简化为Nal2[(Al0.5Si0.5)24O48]·27H2O。
