An innovative, uniaxial ductile fiber-reinforced polymer (FRP)
fabric has been researched, developed, and manufactured (in the
ductility of the developed fabric has been investigated by strengthening and testing
eight concrete beams under flexural load. Similar beams strengthened
with currently available uniaxial carbon fiber sheets, fabrics, and
plates were also tested to compare their behavior with those
strengthened with the developed fabric. The fabric has been
designed so that it has the potential to yield simultaneously with
the steel reinforcement of strengthened beams and hence, a ductile
plateau similar to that for the nonstrengthened beams can be
achieved. The beams strengthened with the developed fabric
exhibited higher yield loads and achieved higher ductility indexes
than those strengthened with the currently available carbon fiber
strengthening systems. The developed fabric shows a more effective
contribution to the strengthening mechanism.

微软推出的专用于VS2005代码编辑器的字体,根据介绍,这种字体使用的是微软在下一代操作系统 Windows Vista 中使用的ClearType 技术。
ClearType不是专门的字体,而是一种显示技术,可以称为"超清晰显示技术",它是专门为液晶显示器用的,可以大大增强所有文字的显示清晰度(包括中文),而且,普通的显示管显示器(阴极射线管显示器)也可以使用。效果大大增强。非常好。
