Highest in the world of China's reserves of lead, but the growing phenomenon of Lead Mine shortage of resources, the development of Secondary Lead Industry can reduce the native lead ore extraction, production and regenerated lead directly from lead waste recycling, do not like the production of primary lead through mining, as , ore dressing and other processes, Secondary Lead production costs lower than 38% of native lead.

最高的铅中国的外汇储备世界，但铅矿资源短缺现象日益严重，对再生铅工业的发展，可以减少原生铅矿石开采，生产和再生铅铅废物回收，直接，不喜欢通过采矿生产作为，选矿和其他进程，再生铅生产成本低于38％的原生铅的主要领导。

In the experiments, some facters such as the proportion of tetraethyl orthosilicate to coupling agents and distilled water to tetraethyl orthosilicate,the concentration of ammonia,reaction time and reaction temperature were controlled.

研究了正硅酸乙酯与偶联剂的比例、水硅比、氨水用量、反应温度与反应时间等因素对包覆效果的影响，其中重点讨论了偶联剂的添加方式对成膜效果的影响。

Metal/ oxide composite aerogels can be used as catalysts because of their high specific surface area. In this paper, Co-rich Co/SiO2 composite aerogels in which mass fraction of Co can reach 66%were firstly prepared by sol - gel process of Co-containing tetraethyl orthosilicate. The influence of H2O, catalyst, solvent and composition of Co-containing tetraethyl orthosilicate on the sol-gel process are discussed.

本工作首次采用含钴硅酸乙酯进行溶胶～凝胶反应来制备高钴含量的纳米级Co/SiO2复合气凝胶，制备的Co/SiO2复合气凝胶中n：n的比例最高可达2：1，且复合气凝胶中的Co含量可在小于66％的范围内任意调节，并系统研究了水量、催化剂浓度、溶剂量及含钴硅酸乙酯的组成对溶胶-凝胶过程的影响。

tetraethyl lead：四乙铅

尽管人们担心存在健康威胁,但四乙铅(tetraethyl lead)还是被加进美国销售的汽油当中. 在接下来的几十年间,空气中的铅将毒害土壤、水和食物. 铅会遗留在人骨中,并对儿童大脑造成先天性损坏. 最初人们生产聚氯联二苯(PCB)是用于电子变压器、液压机液体、增塑剂和黏合剂.

tetraethyl lead：四乙基铅

四乙基铅 (tetraethyl lead) 提一种是在汽油中加入抗爆剂,另一种方法是采用含有高辛烷值烃类成分的汽油炼制工艺. 在众多种类的抗爆剂中,人们发现四乙铅的抗爆效果特别显著,只要少量的四乙铅就能大大提高汽油的辛烷值,因此,从 1921年起,
