Apostilb是英语单词，没有中文对应的翻译。这个词语是光学领域中用来表示照度衰减速率的单位，通常用于描述物体表面反射光的亮度变化。
例如，在光学测量中，人眼的感知光度随着距离的增加而迅速下降，Apostilb可以用来比较两个不同距离的区域之间的亮度差异。
以下是9个含有Apostilb的例句：
1. The surface of the moon reflects sunlight at about 7 Apostilbs.
月球表面反射的阳光大约是7个Apostilb。
2. The display of the new phone has a peak brightness of 500 Apostilbs.
新手机的显示屏亮度峰值为500个Apostilb。
3. The wall paint has a gloss level of 80 Apostilbs at an angle of 85 degrees.
墙壁漆在85度角度下的光泽度为80个Apostilb。
4. The camera lens has a total light transmission of 95%, resulting in a loss of just 0.5 Apostilbs at the image plane.
相机镜头总光透过率为95％，导致图像平面仅损失0.5个Apostilb。
5. The difference in brightness between two adjacent areas is only 2 Apostilbs, making it difficult to distinguish them visually.
两个相邻区域之间的亮度差仅为2个Apostilb，使得它们在视觉上难以区分。
6. The LED lighting system provides a uniform illumination of 20 Apostilbs across the entire display area.
LED照明系统提供整个显示区域均匀照明为20个Apostilb。
7. The cat's eyes have a light reflectivity of 130 Apostilbs, which is why they shine so brightly in the dark.
猫眼睛的反光度为130个Apostilb，这就是为什么它们在黑暗中如此明亮。
8. The surface of the water has a low reflectivity of only 2 Apostilbs, making it difficult to see objects beneath the surface.
水面反光度只有2个Apostilb，使得难以看清水下物体。
9. The glossy brochure reflects light at about 70 Apostilbs, making it appear very bright and eye-catching.
光泽的宣传册反射光线大约为70个Apostilb，使其看起来非常明亮和引人注目。
