源气体流量比对F-DLC薄膜结构的影响

以高纯石墨作靶，CHF3/Ar作源气体采用反应磁控溅射法制备出了氟化类金刚石（F-DLC）薄膜。拉曼光谱表明，CHF3相对流量的增加会引起薄膜的D峰与G峰强度之比I（D）/I（G）减小，晶粒增大，芳香环结构出例下降。红外吸收光谱分析证实了这些推论，指出这是由于薄膜中氟含量上升的结果。     

Composition and structure of Ti-C／DLC graded composite filmsc

The Ti-C→DLC gradient composite films were characterized systematically. The elemental depth profile and elemental chemical state evolution were determined by X-ray photoelectron spectroscopy (XPS). The transmission electron microscope (TEM) and high-resolution transmission electron microscopy (HRTEM) were used to study the structure of interracial zone between DLC film and Ti-C layers. Results show that there are composition transition zone between DLC film and either Ti-C layer or steel substrate on condition that pre-deposited Ti layers on the steel substrate then plasma based bias deposited DLC films. In Ti-C graded layer, the chemical state of titanium and carbon are changed gradually.The structures of zone in Ti-C layer near the DLC film is consisted of random oriented nanocrystaUines TiC dispersed in amorphous DLC matrix. The structure of the zone between DLC film and Ti-C graded layer is gradually changed too.     

小编寄语

努力工作,拼命玩！《边境之地2》的欢乐联机之旅还在继续中,《生化危机6》的联机热潮已经到来,幸好10月中下旬暂时没什么联机大作,不然真是没时间打了。（谜之声：《边境之地2》的机械萝DLC已经出了,     

自由竞速与气候变化

说起“《极限竞速地平线》系列”的特点,就在于它是一款开放世界的自由驾驶体验游戏。玩家可以在风景如画的世界当中自由驰骋。作为系列的第二作,本作将延续系列传统。玩家可以在世界中自由地进行探索。在这个过程中。还能参加到赛事以及一些特殊比赛当中。作为游戏的新要素,本作存在着名为“目标清单《Bucket Listr’的要素。这是一个挑战要素。玩家可以挑战意大利或者是法国的清单以解锁更多的游戏要素。而这项要素会随着今后的DLC不断填充。确保游戏有足够的耐玩度让玩家继续沉浸其中。同时基本的游戏要素上。有超过700项以上的赛事。包括赛车类、探索类等等。所以玩家在自由游戏的同时。也能有一定的目标去推进游戏发展。
