温度响应相变材料(PCMs)的微区黏度和自由体积等性质在熔点附近会发生可逆且快速的变化,这种变化可以放大荧光探针的响应性.本文合成了2个对高黏度具有比率响应发光的新型三芳基硼化合物4-(1-{4-[双(4-溴-2,3,5,6-四甲基苯基)硼烷基]-2,3,5,6-四甲基苯基}哌啶-4-基)吗啉(MPDB1)和4,4-({[(4-溴-2,3,5,6-四甲基苯基)硼烷二基]双(2,3,5,6-四甲基-4,1-亚苯基)}双(哌啶-1,4-二基))二吗啉(MPDB2),并将其与相变材料结合,制备了高灵敏度比率荧光温度计.由于化合物的高黏度响应性质,其在相变材料中的温度荧光响应范围低于体系熔点,因此得到在量程范围内为纯固体的相变材料荧光温度计,具有良好的加工性.作为黏度探针,一取代的MPDB1的荧光响应范围为100~3000 mPa·s,灵敏度高;而二取代的MPDB2则在100~46000 mPa·s的黏度区域有荧光响应,覆盖范围广.作为温度探针,MPDB1-聚乙二醇20000(PEG20000)体系的荧光温度响应区间为-10~50℃,最大相对灵敏度(Sr)为3.5%(10℃),绝对灵敏度(sa)为4.6%(30℃),灵敏度较高,且其温度测量范围可以通过取代基数目和选用不同熔点的聚乙二醇介质调整,具有较强的适用性.

元代安西王府属官设置,反映了安西王统治秦蜀地区的情况,也可由此审视元朝分封制度及王府设置情形。王相府为安西王政务机关及秦蜀地区最高军政机构,王相身兼辅佐安西王及行使地方权力双重职能。安西王府文职属官名称多袭自金朝,任职者... 详细信息

元代安西王府属官设置,反映了安西王统治秦蜀地区的情况,也可由此审视元朝分封制度及王府设置情形。王相府为安西王政务机关及秦蜀地区最高军政机构,王相身兼辅佐安西王及行使地方权力双重职能。安西王府文职属官名称多袭自金朝,任职者多为地方儒士;武职属官多系从征秦蜀军帅家族成员。此外,王府尚有奥鲁赤、医药提举、掌祠事、经籍官、司天台判等特定职事设置。安西王府属官设置在地方层面复制朝廷的基本功能,是安西王特殊权力的体现。安西王府具有人才储备功能,王府属官不仅负责王府及其领地事务,也可出任地方官。至嗣王阿难答时期,王府属官任免受到中央乃至行省牵制,折射出安西王权力的升降。

清代商民路票档案,是汉蒙民族长期交往交流交融过程中形成的珍贵史料。商民路票档案中的商人身份、货物种类和商队成员信息,对研究清代汉蒙民族交往交流交融具有不可替代的历史价值。然而,至今尚未发现对其进行整理研究的论著,需要挖掘和利用。论文选取清代阿拉善和硕特旗境内商民路票档案,对商民改用蒙古名字现象进行历史性考察,分析了从行商向坐商转变的过程中表现出来的汉蒙民族交往交流交融的不同形式和内容,揭示了汉蒙民族在商业贸易领域交往交流交融的阶段性特征。商民在行商阶段改用蒙古名字,是商民在蒙古族人聚居地区生存和发展的需要,也是该阶段汉蒙民族交往交流交融的具体体现。在汉蒙贸易双方互相认同和接纳时,双方关系发生了根本性转变。蒙古族人开始学会经商,出现汉蒙民众合伙经营贸易的新形式。早期商民的蒙古化和蒙古族人日趋汉化的现象,都是汉蒙民族之间的相互认同和相互交融的表现。
