以经部分硝化和还原的低分子量聚苯乙烯为母链，利用其胺基和丙烯酰基异硫氰酸酯加成，合成了一种新型有机高分子型PVC 热稳定剂——丙烯酰基硫脲接枝聚苯乙烯，其结构经IR和元素分析表征。

On the basis of atmospheric corrosion analysis and on the premise of unaltered originappearance of metal antiquity, a novel systematic technology of rust stabilized conversion and corrosioninhibition for archeological iron was developed in this thesis. Model occulted corrosion cell was used to studythe formation of bronze powder rust, its characteristics of pit corrosion and effect factors. The filmingtreatment of azoles composite corrosion inhibitors was used to prevent silver tarnishing, and its anti-tarnishingmechanism was proposed by measurement of electrochemical techniques and Surface-enhanced Ramanscattering.

在不改变文物原状的前提下，本文基于对金属质文物大气腐蚀过程的分析，发展了一种新的铁器文物表面锈层稳定转化与缓蚀保护的系统处理方法，用&模拟闭塞电池&的方法研究青铜器文物&粉状锈&的形成、点蚀特征和影响因素，采用唑系复合缓蚀剂成膜处理技术防止银器文物变色，利用电化学方法、SERS等方法研究并提出了唑系复合缓蚀剂防银变色的作用机理。

The second consideration is properly connecting the ends of the aluminum magnet wire. The reason for this goes back to your high school chemistry course. You may remember that aluminum oxidizes much faster than other metals—in fact, if exposed to air, powdered aluminum will completely oxidize in a few days, forming a fine white powder.

第二个需要考虑的是铝漆包线的正确的端接，其原因你可以回忆一下你高中的的化学课程，你应该还记得铝比是其他金属更容易氧化的，如果暴露在空气中，铝粉会在几天内完全氧化，变成了很细的白色粉末。
