Fortunately, in some special areas of China, there are some thick loess profiles with higher resolution and sedimentary rate, which were formed in the last interglacial.
幸运的是,在中国的一些特殊地理区域,的确存在末次间冰期的一些厚层黄土剖面,其沉积速率与分辨率都特别高。
But, low sedimentary rate in many profiles, especially in S1, and following strong pedogenesis and eluviation would have effect on those climate records.
然而,黄土高原中部大多数剖面由于沉积速率较低(特别是S1地层),加上后期强烈的成壤作用和淋溶作用可能影响其气候记录。
Melt pumping characteristics, velocity and shear rate distribution profiles of the screw assemblies are analyzed and discussed.
分析并比较了组合螺杆的熔体输送特性、速度场和剪切速率场分布规律。
