建立了压敏漆动态特性的两种模型。这两个模型中的第一个是设计模型和补偿器的纯经验方法。第二个模型包含了油漆层上的不稳定压力场对油漆层的影响，并导致发光强度随时间波动的过程的物理过程。在该第二模型中，选择两种不同形式的静态校准。证明了标定对系统动态特性的影响。标称值A =振幅a =压敏漆厚度B =线性Stern-Volmer静态校准的截距c =校准常数D =扩散率E =活化能f =从压力到强度的校准函数g =从强度到压力的校准函数H =传递函数I =积分强度J =每单位厚度的强度j =复数，p i1 K =相对于表面条件的每单位厚度的强度误差M =模型阶数m =相对于表面条件的氧浓度差n =氧浓度P =压力T =温度t =时间x =距基底的距离® =模态ε =本征值ae =溶解度？=时间常数A =相位9 =空间本征函数！=频率
Two models for the dynamic behavior of pressure-sensitive paints are developed. The e rst of the two models is a purely empirical approach to designing a model and compensator. The second model presented encompasses the physics of the process by which an unsteady pressure e eld over the paint layer affects the layer and causes an intensity of e uorescence that is e uctuating in time. Within this second model, two different forms for the static calibration are chosen. The effect of the calibration on the system dynamics is demonstrated. Nomenclature A = amplitude a = pressure-sensitive paint thickness b = intercept of linear Stern ‐Volmer static calibration c = calibration constants D = diffusivity E = activation energy f = calibration function from pressure to intensity g = calibration function from intensity to pressure H = transfer function I = integrated intensity J = intensity per unit thickness j = the complex number, p i1 K = intensity error per unit thickness relative to surface condition M = model order m = oxygen concentration difference relative to surface condition n = oxygen concentration P = pressure T = temperature t = time x = distance from substrate ® = modal states ¸ = eigenvalues ae = solubility ? = time constant A = phase 9 = spatial eigenfunctions ! = frequency
