4 . a novel amperometric sensor has been constructed for the determination of h2o2 . it was based on catalyzing electroreduction of hydrogen peroxide by metal hexacyanoferrate , which were electrodeposited on gold wire electrodes , under a certain potential 利用循环伏安法，在金电极表面电化学沉积一层铁氰酸镍膜（ nihcf ） ，在一定电位条件下，它能快速催化还原过氧化氢，其响应电流与过氧化氢的浓度呈线性关系。
Contained within the egg is a detachable surprise - - a basket of delicate spring flowers , each carved from a single piece of white quartz fashioned with gold wire stem and stamens , jade leaves and green garnet centers 彩蛋的里面还另有玄妙，让人叹为观止：在这枚小小的水晶蛋里面还有一个盛满精美花朵的花篮，每一朵花都是由一块白色的石英雕刻而成的，花茎和花蕊由金线制成，叶子由玉石制成，而叶子的中心则是绿色的石榴石。
The whole process of copper wire ball bonding and gold wire ball bonding were compared and analyzed , and a central composite design of experiment ( doe ) approach was applied to optimize the parameters of free air ball formation process and bonding process , separately 本文首先对比分析了铜丝球键合和金丝球键合的全过程,采用实验设计分别对烧球工艺参数和键合工艺参数进行了优化。在此优化参数下,获得了连接良好的铜丝球键合点和金丝球键合点。
