Biodegradable polymers have shown great potentials in biomedical field and environment protection.As an inherant property, biodegradability has been widely investigated in terms of weight loss, morphological change and biodegradation rate in order to well control the biodegradation behavior of polymer materials.It has been known that the biodegradation results in the characteristic change of polymer morphology which begins from surface or interior of polymer materials, depending on the biodegradation mechanism.Such kind of biodegradation results in the changes of both morphological and chemical structures of materials, therefore from the viewpoint of tissue engineering,biodegradation-induced morphological change could be regarded as an efficient tool for the surface control of polymer materials as cell growth matrix.

氮氧化物(NOx)是大气污染的主要有害物质之一,氮氧化物有N2O、NO、NO2、N2O3、N2O4和N2O5,总称为NOx,其中污染大气的主要氮氧化物是NO和NO2.大气中的氮氧化物是形成酸雨酸雾的主要污染物,同时破坏臭氧层,形成光化学烟雾,对人体具有致毒作用.因此,在燃烧过程中,必须对氮氧化物的排放进行严格控制.2015年1月1日开始执行的国家标准《炼焦化学工业污染物排放标准》对大气污染物NOx
