运动场表面.镜面反射率的测定 - Surfaces for sports areas - determination of specular reflectance ; german version en 13745 : 2004
运动区域用表面.镜面反射率的测定 - The reflectivity value obtained by calculating the difference between the inclusion and exclusion of specular reflection is a direct measurement of surface gloss
通过计算镜面反射率的内含和外延的不同获得的反射率的值是直接测量表面光泽的结果。 - Aluminium and aluminium alloys - anodizing - part 11 : measurement of specular reflectance and specular gloss of anodic oxidation coatings at angles of 20 o , 45 o , 60 o or 85 o
铝和铝合金.阳极化.第11部分:以20度45度60度或85度角度测定阳极氧化层的镜面反射率和镜面光泽 - The conclusions are as follows : the ultrasonic intensity is proportion to the laser intensity ; the ultrasonic induced by a laser line source has much more advantages than by a laser point source , such as stronger energy , higher snr , more directivity and shape ; the intensity of cfpi ' s output signal is linear with ultrasonic vibration velocity , and is effected by incidence angle and scattered angle ; snr will increase by reducing cfpi ' s bandwidth , reducing incidence angle , increasing cavity ' s length and reflectivity
在分析点光源激励声表面波机理的基础上，求出了线光源激励的超声振动的位移表达式，发现线光源激励的近场区表面波具有波形好，信噪比高，指向性好，幅度强等特点。通过理论推导，得出共焦fabry - perot干涉仪的输出光强除了与样品表面的振动速度成正比，并与入射角和散射角有关；适当减小cfpi的带宽，增加腔长，增大镜面反射率，或者减小检测入射角都可以提高系统的信噪比。
