你的作品呢

女人是个好女人，秀丽，贤慧，聪颖，而且还有一张烫金的文学学士证书。像所有女人一样，她恋爱，结婚，生子，一切都很平常。她的丈夫在研究所工作，担任了一个研究课题组的组长。为了丈夫的事业，她担任起了相夫教子的全部重担，包揽了所有的家务。丈夫在研究领域有了成果，在圈内也很有名气。每当听到别人赞扬他的丈夫，她的喜悦之情便溢于言表。她认为丈夫就是她的作品———一篇很有内涵的小说。她准备创作自己的第二件作品———他们的孩子。就在这一年，她遭遇了失业，她所在那家单位因为经营不善，破产了。她连工资都没有了。于是，…     

Studies of Several Systems with Air Electrode Electro-Synthesizing H2O2 on the Spot for Degrading Aniline in Aqueous

A gas diffusion electrode (air electrode) with a high current efficiency of electro-synthesizing H2O2 using O2 in air was prepared. The several systems with air electrode as cathode of electro-synthesizing H2O2 on the reaction spot for degrading aniline in aqueous--electro-Fenton system, photo-excitation electro-H2O2 system and photo-electro-Fenton system, were developed. The rates of decomposition of H2O2 and mineralization of aniline were experimentally measured respectively under different conditions, and the results indicated there has an excellent parallel relation between decomposition rate of H2O2 and mineralization rate of aniline. Especially, photo-electro-Fenton system, where H2O2 is decomposed the fastest, is the best system of oxidizing and degrading organic toxicants. Compared photo-electro-Fenton system with photo-Fenton system, important role is revealed in the interface of air electrode. In this paper, the mineralization mechanism of aniline in the photo-electro-Fenton system was also discussed.
