在室温下，以掺Yb3+的MCM-41作为主体，“热处理”后的Tb(aspirin)3phen作为发光客体，将其进行组装，通过XRD和N2-吸附脱附和IR对组装体的结构和物理性质进行了研究。利用激发和发射光谱分析了组装体的光致发光性能和主客体关系。采用了一种新型的掺杂方法“直接焙烧法”，用以避免在试样合成中掺杂离子的损失。在Yb/MCM-41和Tb(aspirin)3phen-Yb/MCM-41的X...
在室温下，乙二胺环境中合成了高度有序的介孔材料MCM-41，并将经热处理的发光客体Tb(aspirin)3phen 组装进其孔道，通过激发发射光谱对其光致发光性能进行了研究。结果表明，Tb(aspirin)3phen 240～375 nm区间的宽激发峰归属于配体aspirin羰基n→π*跃迁、苯环π→π*跃迁，和phen的杂菲基团吸收，Tb3+的特征发射是由于Antenna效应引起的。相对于纯Tb...

Since it is proposed that reactive oxygen species (ROS) is involved in the pathogenesis of various diseases, low-molecular weight superoxide dismutase (SOD) mimetic complexes have been intensively stu...
在室温下，将MCM41和热处理后的发光客体Eu(aspirin)3phen进行组装，通过XRD、N2吸脱附和PL等表征技术对组装体进行了研究，考察其光致发光性能。结果表明：Eu(aspirin)3phen进入MCM-41孔道后，充当了“二次模板剂”，使MCM-41的骨架有序性增加。经热处理后Eu(aspirin)3phen与MCM41组装后，组装体的发光强度与相应Eu(aspirin)3ph...

新疆蒙古族对糖精和乙酰水杨酸尝味能力的分析Analysis of Saccharin and Aspirin Tasting Ability among Mongolians of Xinjiang
新疆蒙古人 糖精 乙酰水杨酸 味盲率 基因频率
2007/12/29
对710名（男328人，女382人）新疆蒙古族进行了糖精和乙酰水杨酸尝味能力的检测分析。结果表明，蒙古人群中的糖精味盲率为4.648%,没有尝味能力的隐性基因频率为0.2156，具有尝味能力的显性基因频率为0.7844，平均尝味阈值为8.009±1.34（0.108mol/L）。乙酰水杨酸的尝味阈值分布出现了非常明显的双峰一谷分布，表明该性状是单基因决定的性状，谷底7号液（3.00×10-4 mo...
