Need laminating of gilded with gold foil often worry about is easy to clean the first hot stamping and then covered with plastic film, which produce: cyclophos phamide sub-gloss film will destroy the anodized finish, not water soluble glue film covering, or it will cause anodized surface nigrescent, at the same time easy to cause we recreate the stuck to the pictures and texts issued on virtual phenomenon caused by the edge.

需要覆膜加工的烫金，人们常担心金箔容易擦落而先烫印再覆膜，这易造成：①薄膜会破坏电化铝表面光泽性，不宜采用水溶性胶水覆膜，否则会造成电化铝表面发黑，同时极易造成金粉粘在图文边缘造成发虚现象。

Even though noctilucent clouds were sometimes seen in the past., all this extra methane carries more water vapor into the upper atmosphere, where it condenses at much higher altitudes to form more clouds that the sun's rays still strike long after sunset has brought the beginning of night to the surface far beneath them.

虽说过去天空偶尔也出现过夜光云团，但大气层中所含的那些过量的甲烷会将更多的水蒸气带到高层大气中；水蒸气在更高处凝结，会形成更厚的云层，夜幕降临以后很久，这些位于高空的云层下方还在受着太阳光的照射。

In order to increase the practical application of this waster water treating technology, in this text, we tried to improvement the feasible on economy and technology from preparation of photocatalysists, design of reactor and the influence of different reaction conditions etc.A P25 TiO2 film supported on UV light surface was prepared using sol-gel method at 200℃ calcinations temperature, and the photocatalyst has shown a good stability and performance for the photodegradation of orthocresol solution irradiated with UV light of 254nm, when reaction for 30min, the photodegradation still more then 85%.
