质量磁化率 meaning in Chinese
mass susceptibility
Examples
- With the widespread and profound impacts of global change on the natural elements and progress , the society and economy , and even the human activities , the study of global change has become one of the most active frontiers in the current earth science research field . especially , climatic and environmental changes of holocene and human history is a very important time scale of the study of global change . however , the geographic surroundings and the natural environment of the southern margin of tarim basin , which lies in the hinterland of eurasia continent , are so special that it is difficult to obtain the proxies indicating its environmental evolution
在多年来前人研究成果的基础上，本文通过尼雅剖面年代分辨率可达10a的沉积物质量磁化率、碳酸盐碳同位素、粒度等气候替代性指标及约特干剖面的地球化学元素、孢粉等气候指标信息的结果分析，并结合达木沟、塔格勒等剖面的成果及相关资料，得出以下结论： ( 1 ) 、南疆塔里木盆地南缘中全新世6 . 7 3 . 0kab . p .以气候温暖偏干的荒漠环境为总体特征。 - O curve of dsdp607 v30 - 97 show that loess began to deposit on the terrace of the yellow river about 1 . 20 ma b p , and passed thirteen climatic changes from drier and cooler to warmer and wetter later . the turn of sedimentation from alluvium to loess , an event of transformation from accumulation to down - cut of the yellow river , indicates a sharp tectonic uplift occurred around 1 . 2 ma b p . key words : loess - paleosol ; susceptibility ; climatic changes ; tectonic movement ; yellow river ; yangfan section
通过对杨范剖面黄土地层岩性特征沉积结构质量磁化率和频率磁化率的分析及与深海氧同位素曲线的对比，划分了剖面地层，初步确定了黄土沉积始于1 . 20 ma b p ,黄土沉积以来该区发生了13次大的干冷暖湿气候变化沉积转型指示河流强烈加积转变为河流侵蚀，代表约在1 . 20 ma b p发生过一次强烈的构造抬升事件。
