我想你要问的主要是传感方面的区别，拉曼光纤是一种测温模式，是一种分布式光纤测温模式，也就是说测试光纤的任何部分都可以感知温度。光纤光栅是一种准分布传感模式，也就是一种点式的光纤传感模式，只有刻有光栅的光纤部分才可以感知。在我的博客里对这两种光纤传感模式都有介绍，你可以看看。http://hi.baidu.com/fibersensor

In this study， active reforming catalysts for use of gasification of biomass compounds in aqueous medium were developed by depo-sition of platinum on various supports (activated carbon， titanium dioxide， alumina， single-walled and multi-walled carbon nano-tubes， graphene oxide and tungsten oxide-zirconium oxide) using nanotechnological approaches in supercritical carbon dioxide media. The effects of supports and platinum reduction methods have been investigated to optimize the catalytic activity of sup-ported platinum catalyst for hydrogen-rich gas production by aqueous-phase reforming of wheat straw biomass hydrolysates and glucose solution. 展开
