The increasing of soil Bray-1 phosphorus was significantly correlated to the dissolved labile phosphorus (p 0.001), and the phosphorus leaching loss under the precipitation of two-times of normal precipitation is more than 3.6 times than that of normal precipitation.

生物固形物的施用会造成表层0-10 cm土壤Bray-1磷的累积，由於土壤中Bray-1磷浓度与洗出液中溶解性反应磷的流失量有显著相关(p 0.001)，且两倍雨量淋洗下洗出液中磷的流失量是正常雨量下的3.6倍，因此，生物固形物的施用仍须考量磷流失的风险。

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。

REE tracing results show that the Bering Sea and Chukchi Sea surface sediments primarily from neighboring mainland . Contrasting with China loess, the average crust results show that the Arctic region is in a dry and cold climate of physical weathering to the Lords environment.

稀土元素物源示踪结果显示，楚科奇海与白令海表层沉积物主要来源于周边大陆；与中国黄土、地壳平均值的对比结果显示，北极地区是处于干冷气候下的以物理风化为主的环境中。

The occurrence percentage of GAB in surficial layer of sediment was higher than that in the other layers. The occurrence percentage, abundance and its variation of GAB in Bering Sea were higher than that in the Chukchi Sea respectively.
