这是自2月13日签署协议后六方的外交官第一次在北京会谈，会谈在乐观的气氛中开始。
The worm - like mesoporous materials were synthesized and characterized with tem , x - ray diffraction , nitrogen adsorption / desorption and ft - ir techniques , etc . the results showed that all the samples had larger porediameter than the samples through calcinations under resembled conditions , but the mesopore ordered poorly . ft - ir results showed hexagonal structural character were kept , but xrd , tem results showed that the samples have the structure characteristics of msu - x . it was analysized that all n2 adsorption isotherms of the samples belong to langmuir iv category which is related to mesoporous materials
Ft - ir光谱表征结果显示，经萃取处理后的介孔sio _ 2材料保持了六方的结构特征；经xrd 、 tem进一步分析，证实所合成的介孔氧化硅材料具有msu - x材料的结构特征， xrd谱图表明样品具有短程有序性：所合成的材料低温n _ 2吸附测试结果表明，各样品的n _ 2吸附等温线均与中孔(介孔)特征的第类曲线基本相符；由kelvin公式计算得到的孔径分布曲线说明，介孔材料具有较为集中的孔径分布；各样品的bet比表面积比较高。
