光子密度 meaning in English

photon density

This system employed diffuse photon density wave ( dpdw ) to detect the heterogeneities in biological tissues , and the rows of its laser sources and detectors were placed in a special way which made it possible to employ a simple algorithm for three - dimensional localization of heterogeneities
该系统利用射频光子密度波来探测生物组织内部的异物，采用特殊的光源和接收器排列以应用简单的算法进行异物的3维定位。
The intracavity photon density and initial population inversion density are assumed to be gaussian distributions instead of plan wave assumption , based on this assumption , the rate equations of diode - pumped intracavity - frequency - doubled passively q - switched laser are modified . through solving these space - dependent rate equations numerically , the results under different assumption are compared . 5
将腔内光子密度和初始反转粒子数的平面波近似修正为高斯分布近似，独立地导出描述二极管泵浦内腔倍频-被动调q激光器的速率方程，并通过数值求解该方程比较了两种近似下脉冲特性的不同； 5 .实验验证了2中提出的实验方案，并对实验结果进行了分析。
