| 摘 要： | Stern-Volmer关系式建立了荧光光强与表面压力之间的函数关系,是光学压敏涂料测压技术的理论基础和核心。从光化学的基本理论和基本模型出发,推导和整理出多种形式的Stern-Volmer关系式,并简要评价分析了每种形式的特点及适用范围,同时,基于Stern-Volmer关系式衍生式,研究分析了压力测量值偏差、最优测压范围和压力灵敏度等压敏涂料特性参数的规律特点以及对PSP测量的影响,得出了一些对PSP测压技术工程应用具有重要参考意义的结论。

| Abstract: | The Stern-Volmer relation is the core and theoretical basis of PSP technique,which describes the quantitative function of the luminescent intensity versus surface pressure.Various forms of the Stern-Volmer relationship based on essential photochemical philosophy and model have been derived as well as the discussion on the properties and limits of the derived equations.Further analyses on relative deviation of measured surface pressure,optimal pressure range for measurement and pressure sensitivity for given PSP formulation have been conducted according to these diverse expressions of Stern-Volmer relationship.At last,several conclusions drawn herein imply a essential reference for engineering application of PSP technique. |
