  step edges
It was established that AgCl nucleation on Ag(111) mainly occurs on step edges but low temperature reaction could also start on atomic terraces.
      
The model takes analytically into account the diffusion of adatoms, an incorporation mechanism and an Ehrlich-Schwoebel barrier at step edges.
      
Step edges experience meandering instability under growth conditions if there is a kink barrier suppressing adatom jumps around kink sites.
      
It is found that clusters of diameter smaller than the Pt terrace width of 2?nm are aligned along the step edges of the Pt(997), thus forming linear cluster chains.
      
If the cluster diameter is larger than the terrace width then the alignment along the step edges is not observed and rather large agglomerates are found which are randomly distributed over the surface.

Si(100) surface was observed with UHV-STM. STM images of clean Si (100) surface were obtained. Two types of step edges in the STM images were analyzed through the formation of the Chadi mode and the anisotropic diffusion of surface atoms. The STM image of Si (100) surface showed the existence of many defects. The position of the defects could be determined from the STM image with positive or negative sample bias in the same area.

The adsorption and dissociation of hydrogen on stepped surface (511) of nickel are studied with the embedded-atom model (EAM) method. The adsorption energy, the length of the adsorption bond and the adsorption height for a single hydrogen atom are calculated. Three kinds of stable sites are found for hydrogen adsorption. There are the double-fold bridge site B on the step edge, the three-fold hollow site H3′ on the step surface and the four-fold hollow sites H1 and H2 on the terrace surface. Compared with a...

The adsorption and dissociation of hydrogen on stepped surface (511) of nickel are studied with the embedded-atom model (EAM) method. The adsorption energy, the length of the adsorption bond and the adsorption height for a single hydrogen atom are calculated. Three kinds of stable sites are found for hydrogen adsorption. There are the double-fold bridge site B on the step edge, the three-fold hollow site H3′ on the step surface and the four-fold hollow sites H1 and H2 on the terrace surface. Compared with a hydrogen atom adsorbed on low-index (001) surface, there are two other adsorption sites near the step: the two-fold bridge site B on the step edge and the three-fold hollow site H3′ on the step surface. At the same time, the absorbability of the hydrogen atom at the site H1 is intensified. The results show that hydrogen adsorption on Ni (511) is affected by the existence of the step. The active barriers, adsorption energy and corresponding bond length for dissociation of a hydrogen molecule on the stepped surface are presented. The results show that the dissociation is easier at the bottom of the step. It is shown that the steps are the active sites for hydrogen adsorption and dissociation.

应用EAM模型研究了氢在Ni(511)面的吸附和解离.首先计算了单个氢原子在Ni(511)面上的吸附能、吸附键长及吸附高度,发现氢在Ni(511)面上有三种相对稳定的吸附位,即台阶棱上的二重桥位B、台阶面上的三重洞位H3′以及平台面上的四重洞位H1和H2.与Ni(001)低指数面相比,明显的增加了台阶棱上的二重桥位B以及台阶面上的三重洞位H3′,并且H1位的吸附性也有所增强,说明台阶的存在影响了氢在Ni(511)表面的吸附性,使台阶附近的吸附位增多且吸附性增强;然后计算了氢分子在台阶表面上解离吸附时的活化势垒、吸附能、氢镍之间键长及氢氢之间的距离,计算结果表明台阶底部更易于使氢分子解离,台阶附近是氢吸附和解离的活性部位.

Adjusting-velocity signal of electromotor is picked up from robot visual picture with a serial of methods.Firstly the key place of visual picture is divided up and valley signal in gray straight-square picture is regarded as threshold,in order to differentiate horizontal and upright surface.Secondly small blobs are cleared up with morphological method and the nearest step slope is selected on basis of middle value.Finally according to step slope,velocities of robot left and right wheels are controlled,for adjusting mobile robot pose.The method is characteristic of good repetition,real-time and easy use.

采用了一系列方法从机器人视觉图像中提取出可供电机调速的信号。先对视觉图像关键部位进行图像分割;随后用灰度直方图中谷底信号作阈值,区分出台阶水平面与竖直面;再用形态学方法消除小斑点;然后采用选取中间值的方法得到台阶斜率;最后用提取出的台阶棱线斜率来控制机器人左右轮的速度,达到调整移动机器人姿态的目的。该方法具有重复性好、实时性强、易使用的特点。
