简介：这份报纸根据地磁气的垂直部件的每日的振幅最小价值时间的数据从1995～2003在Gansu和它的邻近的区域分析地磁气的低值的排水量的分发特征。除了地磁气的低值的排水量本身的变化规则，在地磁气的低值的排水量和中等强烈的地震的出现之间有更好的关联，这被显示出。看起来是在在从1995～2003的9年里的Gansu的中等强烈的地震前的地磁气的低值的排水量。这结果显示那地磁气的低值的排水量具有为到一些程度的地震预言的有启发性的意义。

简介：HoloceneMegathermal被划分成早、中间、迟了的时期，各由于他们改变趋势的不同气候在过时的文化上有不同影响。这研究基于在金海·莱克，记录的环境进化信息的比较分析黄土高原和Zoige和Gansu-Qinghai区域的过时的地点的空间分发的西方的边。结果证明早、中间的时期向温暖、潮湿在Gansu-Qinghai区域作为主要扇区与农业支持了过时的文化的开发，而且，Yangshao文化繁荣的一个全盛时期出现了。Holocene在Gansu-Qinghai区域在5.9kaBP在冷气候事件以后进入了迟了的时期。后来，气候开始变得冷。然而，在5.84.2kaBP，相对稳定的温暖、潮湿的气候在这个区域为过时的年龄的Majiayao文化的发展创造了条件，因此，它的文化遗产地点的分发向高高度和高纬度膨胀了。从4.2kaBP向前，气候变得冷、干燥，它在Gansu-Qinghai区域的过时的文化上有重要影响，在4.2kaBP附近在文化人物和Qijia文化的空间分发导致一个戏剧的变化。在以后一将近300年冷、干燥的时期，统一过时的耕作文化完全崩溃了。以后，畜牧和耕作和地区性的多重文化的一个工业部门形成了，并且最终导致了原始社会并且开始一个使文明的社会的结束。
