三，详细描述：
反光标线亮度，国际上用逆反射系数来表示，单位mcd/lx/m2。其物理意义是：在单位光照条件下，单位面积上产生的亮度值。将仪器置于被测标线的上面，该仪器以数字的形式显示出逆反射系数值，它反映了行车条件下司机对标线反光亮度的客观评价。该仪器由测量主机、电源、充电器、标准板组成。

Three, detailed description:

The brightness of the anti-cursor line, which is expressed in the international reflection coefficient, the unit is mcd / lx / m2. Its physical meaning is: the brightness value generated per unit area under unit lighting conditions. The instrument is placed on top of the marked line, and the instrument displays the value of retroreflective coefficient in digital form, which reflects the objective evaluation of the reflective brightness of the marked line by the driver under driving conditions. The instrument consists of a measurement host, a power supply, a charger, and a standard board.
