摘要： A pressure sensitive paint (24) is coated onto the surface (20) over which a pressure distribution is to be measured. A pressure sensitive paint is a mixture of a silanol-terminated polydimethylsiloxane and methyltriacetoxysilane, and a photoluminescent activeagent such as tris(4,7-diphenyl-1,10-phenanthroline) ruthenium (II) chloride pentahydrate. The binder and active agent are placed into an appropriate amount of a solvent for the binder and the active agent, such as dichloromethane, and applied to a surface (20). In testing of the surface, such as wind tunnel (22) testing, the active agent quantitatively luminesces responsive to the localexternal pressure at the surface.
