采用3种纳米材料构建了一种新型的催化发光(CTL)传感器阵列,并测得10种化妆水在该传感器阵列上的CTL响应曲线。结果表明,不同化妆水在同一种纳米材料表面的CTL响应曲线存在差异;同一种化妆水在不同纳米材料表面的CTL响应曲线也不相同。通过动态时间规整算法(DTW)求算未知样的CTL响应曲线和化妆水模板CTL响应曲线之间的距离,建立三维坐标系,并检验DTW距离的限值,10种化妆水被正确识别。
A novel cataluminescence(CTL) sensor array was constructed with 3 types of nano-materials, and the CTL profiles of ten toners were obtained. The work suggested that different toner's CTL profiles on the same nano-material surface were different while the same kind of toner's CTL profiles on different nano-materials surfaces were also different. By using dynamic time warping(DTW) to calculate the distance between the test and the standard CTL profiles, exhibiting the DTW distance in a three- dimensional coordinate system, examining the DTW distance limit, ten kinds of toner were successfully identified.
