Measurement of Sr/Ca Ratio in Bones as a Temperature Indicator
Sr/Ca ratio Internal body temperature Teeth and bones
2010/10/13
The purpose of this work is to correlate Sr/Ca ratio with internal body temperature from teeth and bones.Results obtained in exploratory measurements using human, bovine and swine teeth indicated some...
采用高温固相法合成Sr4-xCaxSi3O8Cl4:Eu2+荧光材料，利用Van Uitert公式讨论Sr4-xCaxSi3O8Cl4:Eu2+中yEu2+的晶格环境和发光特性，确定晶体中有蓝色和黄绿色两种发光中心，并讨论了它们与光谱结构的对应关系。当0＜x＜0.5，Ca2+固溶入Sr4Si3O8Cl4基质晶格，Eu2+占据八配位Sr2+格位，晶体主要产生蓝色中心的蓝绿色发射;当0.5＜x＜2，较...
