After different sediments ignitions, S was 1.64~2.25 times of that of raw sediment, higher obviously than the sediments without ignition. The aerating pretreatments of sediment and water caused the transformation of bioavailable form to nonavailable form. The bioavailable phosphorus decreased 7.02% and 0.23% respectively compared with that before pretreatment, but the bioavailable phosphorus of the blank test sediment increased 4.85%.

P species, main as Ca-P and organic P forms, showing rego〓 pollution and karst area of lake watershed, inorganic P〓 related to Ca〓, Al〓, Fe〓 content in the overlying water, sediments is not a simple reservoir of dissolved phosphate and particle phosphate, near the interface, near 98% of total P existed as active forms, they may release to overlying water through reduction dissolution, deadsorption in the period of early diagenesis, only 2% of P as fixed forms, which mainly remained in the sediments, sediment was an important resource of nutrients of ovrelying water.

高原湖泊沉积物中的磷以有机磷和Ca-P形式存在为主，反映了高原湖泊流域污染和碳酸盐地区的整体背景，无机磷形式与水体吸附体Ca〓，Al〓和Fe〓的含量有关。底部沉积物不是溶解性磷酸盐和颗粒磷酸盐的长期储存场所，几乎有98%的磷是活性的形态存在，它们通过早期成岩作用在还原条件下还原，溶解和释放又重新回到上覆水体，只有2%的磷以固〓态的形式稳定保存于沉积物中，因此，沉积物为水体营养程度的重要来源。

The fluid sediments imitating the rapidly deposited seabed silts were made in-situ, and an iron plate covered part of the test pit to cut off the effect of the marine hydrodynamics. By field-testing methods, such as static cone penetration test, field vane shear test, the variation of strength is measured at real time, and the marine hydrodynamics' impaction on the consolidation process of the sediments in the Yellow River Estuary was studied.

在黄河三角洲刁口叶瓣潮坪上，开挖2m ×1m×1m 的试坑，现场取土配置黄河口快速沉积形成的流体状堆积物，以铁板部分覆盖试坑隔绝波浪和潮流作用，利用微型贯入、静力触探、十字板剪切试验等原位测试手段，实时测定快速沉积的海床土强度，研究快速沉积的粉质海床土分别在自重条件下以及在波浪和潮波等水动力作用下的固结过程。

Although forest canopy layer could prevent splash erosion effectively, clay was taken away by overland flow and run off easily, the erosion amount became less after removing the forest canopy and surface soil, while the splash erosion still produced in the surface layer; the splash function weakened after having water current, the starting particles were less than bareland, so removing the surface disturbed soil made the erosion amount and clay less, silty sand more than bareland, but unsteady, the wear and tear energy used by raindrop splash and current function for overcoming sediments separating and starting were comparatively large, sediments were very difficult to be started and transported, it explained that forest root systems could increase anti-erosion capability of forest vegetation, make rainfall-current system splash and export finer particles than bareland.

虽然林冠层能有效防止溅蚀的发生，但坡面流还是能带走粘粒部分，粘粒还是容易流失。去除林冠和表层土后，侵蚀量变得更少，但表层还是会被溅蚀，有水流后，溅蚀作用减弱，颗粒起动的比裸地的少，所以，去除表层扰动土后，侵蚀量更少，粉沙多，粘粒比裸地更少一些，但不稳定，雨滴击溅和水流作用用于克服泥沙分离起动损耗的能量较大，很难被起动输移，这说明森林植被根系的作用增加了林地植被的抗蚀力，使降雨一水流系统仅能溅起输出比裸地坡面更细小的泥沙颗粒。

Additionally, the results showed that the Antarctic seal hairs and sediments including seal excrements well preserved the historical information of ancient civilization over the past several thousand years, and the fluctuations of Hg concentration in the seal hairs and the excrement sediments were found to be closely coincided with ancient activities of gold and silver mining

另外，南极海豹毛和生物粪土层中还保存了过去几千年人类文明的历史信息，汞含量的波动与人类冶金文明的盛衰存在明显的响应关系。

REE geochemical characteristics and their systematic changes in the sedimentary section suggest that there existed a process of ingression-regression in this area in the early Cambrian period. The black shale series resulted from the mixing between normal seawater sediments and hot seawater sediments and were deposited under the transitional condition from reduction to semi-reduction and weak oxidation in a shallow-sea clinoform zone of a relatively deep sea environment with dry climate.

稀土元素地球化学特征反映该区早寒武世曾发生过一次明显的海侵-海退过程，黑色岩系为正常海水与热水混合沉积的产物，形成于缺氧还原状态过渡到半还原-弱氧化状态的过程中，沉积环境为干燥气候条件下相对较深的浅海斜坡环境。

The method for measuring resistance parameter of earth body of sediments on surface in deep sea includes steps: in sampling procedure in seabed, closing speed of the perching knife keeps sampling at uniform speed 2cm/s; using current process system of static probing data can analyze resistance data so as to obtain parameters including intensity, compressibility, compaction degree, and thickness state of sediments, and bearing capacity etc.

深海表层沉积物的土体阻力参数的测量方法是在海底取样过程中，该铲刀闭合速度保持2cm/s的匀速取样，用现有的静力触探数据处理系统即可对采集的阻力数据并进行分析，得出沉积物的强度、压缩性、密实度、稠度状态和承载力等参数。

This course covers sediments in the rock cycle, production of sediments at the Earth's surface, physics and chemistry of sedimentary materials, and scale and geometry of near-surface sedimentary bodies, including aquifers.

本课程涉及到岩石循环中的沉积物，在地球表面沉积物的产生，沉积物的物理和化学性质，和近地表沉积体的规模和形状，包括含水层。

If there's no traffic jam, I think it's OK.

如果不塞车的话，我想能行。
