针对温度传感应用研究了(Ba,Sr)_2SiO_1:Eu^(2+)绿色荧光粉荧光光谱的温度特性。在波长405 nm激光的激发下,将样品从室温加热到185℃,在该温度区间内每间隔10℃记录其稳态发射光谱。使用两种新型传感方法,发射谱带的重心波数位置和不同波长的发射强度比得出对应的温度传感方程,并与峰值波长位置随温度的频移变化以及随温度升高发射谱带的展宽情况作了对比分析和讨论,对各温度传感机制和精度作了简要比较、讨论。结果表明,该荧光粉具有多种优秀的点温度传感能力,尤其两种新型温度传感方法具有良好的实用性几与已有传感方法很好地兼容,该荧光材料作为温度敏感材料有较好的应用前景。

理解逻辑后承多元论

河北学刊 2022年第2期42卷 69-78页

作者：王洪光北京大学哲学系北京100871

主张逻辑的多元性,是一个极具争议的逻辑哲学立场。后承多元论是近来最为显著的逻辑多元论学说,它主张逻辑的多元性来自逻辑后承的多元性。本文首先考虑并排除了两类典型的针对逻辑多元论的整体性反驳;其次阐述了直觉性的、非形式的后... 详细信息

主张逻辑的多元性,是一个极具争议的逻辑哲学立场。后承多元论是近来最为显著的逻辑多元论学说,它主张逻辑的多元性来自逻辑后承的多元性。本文首先考虑并排除了两类典型的针对逻辑多元论的整体性反驳;其次阐述了直觉性的、非形式的后承概念的未确定性,以及毕奥和雷斯托尔以此为动机所提出的后承多元论;然后考虑了这个理论的一个直接但饱受质疑的结果,即存在两个不同的经典逻辑后承,尤其说明这个结果在处理逻辑哲学难题时的用处;最后再次回到后承概念的未确定性,探讨了对它的两种理解:含混性和歧义性。
