简介：当世界都在朝向电动化、零排放之际,摩托车自然也要顺应这一潮流.宝马趁着在意大利举办的埃斯特庄园优雅竞赛(Concorsod'EleganzaVillad'Este),展现了他门的全新概念力作零排放的电动摩托车——ConceptLink.跟宝马MotorradVisionNext100Concept相比,这款车要现实得多,更有可能在不久的将来实现,灵巧的它尤其适合在城市市中心驾驶.ConceptLink很难归类,它的造型相当紧凑,车身低矮且拉长,座位平整,不管是从侧面还是从后侧,都可以很轻松地奇上去.它的座位可以调节成两人座,可以是更为动感的单人坐骑,也可以是更为实用的两人坐骑.它的座椅下有存储空间,可以很容易地用滑门打开,既满足了驾驶乐趣,又满足了功能需要.它的车身颜色采用了金属钛和哑光黑,哑光黑区域是动力机构的所在处.

简介：引言AJAX是AsynchronousJavaScript＋XML的缩写。可是如果直接照字面把它翻译成“异步JavaScfipt＋XML”，还是难以直接理解其本意。实际上AJAX作为WEB开发技术的补充，优于传统WEB程序之处在于，它更强调用户体验。而这种体验的改善，是通过减少页面刷新，减少无必要的页面提交等途径来获得的。在其背后的关键是早已成熟的JavaScfipt（当然，VBScript也可以，只是其洳览器兼容性不好）和XmlHttp技术。
