Standard test method for measurement of the luminance coefficient under diffuse illumination of pavement marking materials using a portable reflectometer 用便携式反射计测量路面标记材料在漫射照明时发光系数的标准试验方法
By measuring in transmission , rather than in reflection , it overcomes the limitation imposed by cable loss on the use of the switched reflectometer 该方法对传输信号而非反射信号的测量，克服了电缆线损耗引起的对交换反射计的使用限制。
Optical time domain reflectometer ( otdr ) is a kind of the new type optical malfunction measuring equipment that developed in 1980 ' s 光纤时域反射仪( otdr )是八十年代才发展起来的新型光纤故障测试设备，全称是opticaltimedomainreflectometer 。
A sort of strain sensor that is made of cycloidal stretch film piece and microbent modulation construction and a method of distributed optical fiber strain sensor by optical time - domain reflectometer ( otdr ) are brought forward 摘要提出了一种用圆形弹膜片和微弯调制机构进行应力传感，用光时域反射探测( otdr )技术进行测量的分布式光纤应力传感方法。
A computer - based method and computer - readable medium containing computer - executable instructions for assimilating data collected by a time domain reflectometer and displaying more than two waves representing reflections of a pulse on conductors is provided 提供了基于计算机算法及可被计算机读出的包含着计算机可执行指令的媒体，用以接收由时域反射计收集的信息，显示导体内一个脉冲反射的两个以上的波形。
Finally , we rebuild a soft x - ray reflectometer in 8 - 30nm region by replacing its metal target with low - debris kr and xe aerosol spray targets . reflectivity of soft x - ray multilayer mirrors are measured by the new reflectometer , and the results show the accuracy is about 2 % % 最后，用低碎屑液体微滴喷射靶lpp光源代替污染严重的金属靶lpp光源，改建了一台波段范围8 30nm的软x射线反射率计，并对软x射线多层膜的反射率进行了大量测量，反射率测量重复性达到2 。
