This is not surprising, given the closer proximity of Pengyang to the Asian inland dust sources; The average content of calcium carbonateis of Pengyang section is not only higher than that of central loess plateau, but also higher the west of Chinese Loess Plateau, which reflected Pengyang loess had been deposited by near Liupanshan\'s substances that contained more calcium carbonateis; The content of diffluent element of 10m depth in the section increased fast, which indicated that the modern eluviation and the leaching depth of loess may be stronger than our guess; The soil growth index can reflect the intensity of soil forming and the climatic changes; The "abrupt chang" of glacial and interglacial period was caused by strong soil-forming processes that enlarged the discrepancy of granularity between loess and paleosol. However, the magnetic susceptibility nearly cannot reflect the existence of S_8 and the magnetic susceptibility of S_7 is highest in the whole section, which is inconsistent with other studies that S_5 has the highest magnetic susceptibility.Thin-section examination shows that the micro-texture of the soil layers is divided into both cementing texture in S_7, S_5 and S_1, and granular texture in all others.
与其它剖面相比,彭阳剖面粒度总体上要比东部的洛川、西安,甚至西部的兰州、新疆东湾要粗;CaCO_3平均含量不仅高于黄土高原中部,也高于高原西部,反映出本剖面富含碳酸盐的六盘山近源沉积起到了很重要的作用;易溶元素含量在剖面10m处快速升高,淀积特征明显,反映出黄土受现代淋溶成土作用影响较大,黄土直立、疏松、多孔特性和高温与多雨组合的气候特点,使得元素淋溶、淀积的强度和深度超出了传统的认识和判断;烧失量与其它指标相比,不仅能区分冰期、间冰期;而且能够区分出次一级的冰阶、间冰阶,有较高的分辨率;土壤发育指数、红度能够反映土壤强度差异,是反映气候波动的较好指标;然而,磁化率不能反映古土壤S_8的存在,且S_7的磁化率在全剖面中最高,这与大多剖面S_5磁化率最高的特点不一致。4。

The time of the pedogenic process was in the last ice age, therefore this area was colder and drier in climate and lower in sea level than today. The main chemical process in the soil was oxidation, a period of the formation of oxide minerals such as limonite. With the deposition and covering of the marine facies layer in the postglacial period, the soil turned into diagenetic process. Consequently the chemical process in the soil was dominated by reduction and this process was the main development period for nodules of iron-manganese carbonate to form.
成土期处于末次冰期低海面、气候寒冷干燥期,土壤的化学过程是以氧化作用为主,是褐铁矿等氧化性矿物形成时期;冰后期海相层的沉积覆盖使土壤层进入成者阶段,土壤层的化学过程以还原作用为主,成岩过程是铁锰碳酸盆结核的主要生成期。

Ice/ridge geometric parameters is established, and from computational analysis it is found that the unmonotonous variations of drag coefficient with ice concentration that frequently observed in sea ice field investigation mostly result from the influence of form drag from ice edge.
通过将原型条件下的冰-水总拖曳力考虑成表面摩拖曳力、冰侧形拖曳力和冰脊形拖曳力三部分,建立了冰-水总拖曳系数同海冰和冰脊几何形态参数之间的定量关系,并由计算分析发现现场观测到的拖曳系数随密集度的非单调变化就是冰侧形拖曳力分量作用的重要体现。
