摘　　要：车身反光标识用逆反射系数测量仪是用来测量车身反光标识反光性能的一种光学测量设备,它能够增强车身的可识别性,让后方车辆及时注意并避让,从而降低交通事故发生率。本文叙述了逆反射测量仪的校准方法,对其示值误差测量结果的不确定度进行了评定。The retroreflection coefficient meter for motor vehicle’s reflecting marking is an optical measuring equipment used to measure the reflective performance of vehicle. It can enhance the identifiability of vehicles so as to make rear vehicles pay attention to avoid collision in time,and reduce the incidence of traffic accidents. The article describes the calibration method of the retroreflection coefficient meters and evaluates its measurement uncertainty of indication error.
