腐蚀

The optimized device process of p-n Alo.85Gao.15As/GaAs solar cells have been investigated. AuBe/Au and AuGeNi/Au were evaporated and metallized to form ohmic contacts of front grids and back electrodes, respectively. Heavily-doped GaAs cap layers were removed by the NH4OH:H202:H3P04:H20 selective etching solution.

分别采用真空蒸发AuBe/Au和AuGeNi/Au并合金化形成欧姆接触制作太阳电池正面栅线和背面电极；采用NH_4OH：H_2O_2：H_3PO_4：H_2O体系的选择性腐蚀液去除高掺杂的GaAs接触层；采用真空蒸发技术制备ZnS/MgF_2双层复合减反射膜。

Because in industry expandable graphite is mostly used as seal material and extensively applied in high-tech domains, such as nuclear power plant, avigation and petroleum industry, then often erodes the metal material which connected with it and loses seal , so the sulfur content of the expandable graphite is an important target to achieve , at the same time the industry manufacture need the greater volume .

因为可膨胀石墨在工业上主要被用作密封材料被广泛用在核电站、航空、石油工业等高科技领域，这样，其作为高级密封材料时，常腐蚀与其接触的金属材料，造成密封失效。所以含硫量是一项很重要的指标，同时较大的膨胀体积也是工业生产所需要的。

First,skin regions are detected based on YCbCr model of skin color;each block is morphologically processed in order to smooth out the biconvex and small backdate and to fill holes.Then,skin regions are segmented.At last,a disk template is used to find the location of eye and mouth.

方法首先根据YCbCr肤色模型检测出肤色区域；用数学形态学的膨胀和腐蚀方法进行肤色处理，平滑了边界，同时消除了肤色块的连通；再利用圆盘结构元素对人脸区域做闭运算，从而得到人眼和嘴的位置。
