By field-testing methods, such as static cone penetration test, field vane shear test, and pore water piezometer test, the variation of strength and the pore water pressure are measured at real time, and the marine hydrodynamics' impaction on the consolidation process of the sediments in the Yellow River Estuary was studied. It is shown that the self-consolidated sediments have a very fast consolidation rate, under self-consolidation, in 72h, the consolidation degree reaches 37% and about 142h the pore water pressure disperse over, while under the hydrodynamics, in 72h the consolidation degree reaches 52% and about 195h the pore water pressure disperse over.

The main achievements could be summarized as follows.1. The basic stress-strain characteristics and related physical mechanisms for sands under cyclic rotation of principal stress axes were investigated based on three kinds of drained tests including fixed principal stress axes, cyclic rotation of principal stress axes with magnitudes of principal stresses kept constant, and cyclic changes of principal stresses in both their axes and magnitudes. The main deformation behavior of sands with inherent anisotropy under cyclic rotation of principal stress axes with magnitudes of principal stresses kept constant was obtained in the following.

Based on the rigorous analysis of the kinetic process of both primary and secondary electrons, the related surface charges were analyzed, and the energy gain of emitted electrons was proportional to the square of the ratio between the tangential and normal component of electric field. In this process, the image force of mirror charges would result in an energy loss. Meanwhile, the effect of field alternation of power frequency ac voltage on electron movement could be ignored.

在前人工作的基础上，进一步严格推导了场致一次发射电子和二次电子的运动方程，分析了电子发射引起的绝缘材料表面带电，表明电子发射后的能量增益正比于场强的切向与法向分量比值 F /// F ^的二次方；同时考虑了在电子发射和运动过程中电荷镜像力的作用，并探讨了交流电压下表面带电的情形，认为当考虑电荷镜像力的作用时，电子的能量增益可能变小，而工频交流电压下电场交变对电子运动的影响可以忽略。

With the rapid development of the engineering actions in the highland with particular stratigraphic sequence, because of the buildings at the back of the sliding body and the cutting slope at the front, the pushing force of rock and soil in slope increased, but the anti-sliding force weakened. On the other hand, during the rainfall surface water immerged into the layer interface of the diatomite along the unloading cranny, resulting in the diatomite becoming soft after absorbing water and its shear strength lowered. At the time, the water level went up, the dynamic water pressure and uplift pressure increased, the anti-sliding force continued to reduce. Therewithal, the landslides occurred along sliding surfaces with small tilt angle.

在丘陵区此独特的层序地层近年来随着人类工程活动强度的增大，滑体后缘建筑，前缘切坡，造成下滑力增加，抗滑力减弱；另一方面在降雨的作用下，地表水体沿着卸荷裂隙通道浸入到下伏硅藻土层界面，硅藻土吸水软化，抗剪强度减弱，同时地下水水位上升，动水压力和扬压力加大，抗滑力进一步降低，于是产生了低倾角滑面滑坡。

The plasmid of pEGFP-N1 was preserved in our laboratory.②The rat vibrissa follicles were dissected under a stereomicroscope. The dermal sheath was moved by incubated in dispase. The bulge regions of the hair follicles in anagen phase were carefully cut between the arrector pili muscle and the sebaceous gland, and then incubated with a mixture of trypsin and EDTA.
