验光检测结果FAR PD和NEAR PD分别表示远视瞳孔间距和近视瞳孔间距。1. 远视瞳孔间距是指测量者用瞳孔所在中心到鼻梁两边瞳孔间中心的水平距离来表示，通常是针对远距离的视力测试，例如开车等。2. 近视瞳孔间距是指测量者用瞳孔所在中心到鼻梁两边瞳孔间中心的水平距离来表示，通常是针对近距离的视力测试，...
FARPD指的是患者在看远处物体时的瞳孔距离，NEARPD指的是患者在看近处物体时的瞳孔距离。如果FARPD和NEARPD的值相差较大，那么患者可能需要配制双光度镜片或者渐进式镜片，以便在看远处和近处时都能够得到清晰的视觉效果。
What do Far PD/Distance PD & Near PD mean?When we talk about PD (Pupillary Distance), we need to distinguish between:Far PD/Distance PD: it is used for single vision eyeglasses and refers to the distance between the centers of the pupils, when the user is looking at a distance. ...
received echoes from the microphone signal SNR:(Signal-to-noise Ratio) 信噪比(訊噪比),是科学和工程中所用的一种度量,用于比较所需信号的强度与背景噪声的强度。其定义为信号功率与噪声功率的比率,以分贝(dB)为单位表示。大于比率1:1(高于0分贝)表示信号多于噪声FarEnd andNearEnd Double Talk (DT ...
We report two-dimensional near-field imaging experiments of the 11.9-nm Sn X-ray laser that were performed with a set of novel Mo/Y multilayer mirrors having reflectivities of up to 40% at normal and at 45掳 incidence. Second-moment analysis of the X-ray laser emission was used to ...
